Abstract
BACKGROUND AND OBJECTIVES Whether patent foramen ovale (PFO) closure benefits older patients with PFO and cryptogenic stroke is unknown because randomized controlled trials (RCTs) have predominantly enrolled patients younger than 60 years of age. Our objective was to estimate anticipated effects of PFO closure in older patients to predict the numbers needed to plan an RCT. METHODS Effectiveness estimates are derived from major observational studies (Risk of Paradoxical Embolism [RoPE] Study and Oxford Vascular Study, together referred to as the "RoPE-Ox" database) and all 6 major RCTs (Systematic, Collaborative, PFO Closure Evaluation [SCOPE] Consortium). To estimate stroke recurrence risk, observed outcomes were calculated for patients older than 60 years in the age-inclusive observational databases (n = 549). To estimate the reduction in the rate of recurrent stroke associated with PFO closure vs medical therapy based on the RoPE score and the presence of high-risk PFO features, a Cox proportional hazards regression model was developed on the RCT data in the SCOPE database (n = 3,740). These estimates were used to calculate sample sizes required for a future RCT. RESULTS Five-year risk of stroke recurrence using Kaplan-Meier estimates was 13.7 (95% CI 10.5-17.9) overall, 14.9% (95% CI 10.2-21.6) in those with high-risk PFO features. Predicted relative reduction in the event rate with PFO closure was 12.9% overall, 48.8% in those with a high-risk PFO feature. Using these estimates, enrolling all older patients with cryptogenic stroke and PFO would require much larger samples than those used for prior PFO closure trials, but selectively enrolling patients with high-risk PFO features would require totals of 630 patients for 90% power and 471 patients for 80% power, with an average of 5 years of follow-up. DISCUSSION Based on our projections, anticipated effect sizes in older patients with high-risk features make a trial in these subjects feasible. With lengthening life expectancy in almost all regions of the world, the utility of PFO closure in older adults is increasingly important to explore.

Abstract
BACKGROUND We investigated outcomes in patients with intracerebral haemorrhage (ICH) according to prior anticoagulation treatment with Vitamin K antagonists (VKAs), direct oral anticoagulants (DOACs) or no anticoagulation. METHODS This is an individual patient data study combining two prospective national stroke registries from Switzerland and Norway (2013-2019). We included all consecutive patients with ICH from both registries. The main outcomes were favourable functional outcome (modified Rankin Scale 0-2) and mortality at 3 months. RESULTS Among 11 349 patients with ICH (mean age 73.6 years; 47.6% women), 1491 (13.1%) were taking VKAs and 1205 (10.6%) DOACs (95.2% factor Xa inhibitors). The median percentage of patients on prior anticoagulation was 23.7 (IQR 22.6-25.1) with VKAs decreasing (from 18.3% to 7.6%) and DOACs increasing (from 3.0% to 18.0%) over time. Prior VKA therapy (n=209 (22.3%); adjusted ORs (aOR), 0.64; 95% CI, 0.49 to 0.84) and prior DOAC therapy (n=184 (25.7%); aOR, 0.64; 95% CI, 0.47 to 0.87) were independently associated with lower odds of favourable outcome compared with patients without anticoagulation (n=2037 (38.8%)). Prior VKA therapy (n=720 (49.4%); aOR, 1.71; 95% CI, 1.41 to 2.08) and prior DOAC therapy (n=460 (39.7%); aOR, 1.28; 95% CI, 1.02 to 1.60) were independently associated with higher odds of mortality compared with patients without anticoagulation (n=2512 (30.2%)). CONCLUSIONS The spectrum of anticoagulation-associated ICH changed over time. Compared with patients without prior anticoagulation, prior VKA treatment and prior DOAC treatment were independently associated with lower odds of favourable outcome and higher odds of mortality at 3 months. Specific reversal agents unavailable during the study period might improve outcomes of DOAC-associated ICH in the future.

Abstract
BACKGROUND AND OBJECTIVES Cerebral small vessel disease (SVD) is the major cause of intracerebral hemorrhage (ICH). There is no comprehensive, easily applicable classification of ICH subtypes according to the presumed underlying SVD using MRI. We developed an MRI-based classification for SVD-related ICH. METHODS We performed a retrospective study in the prospectively collected Swiss Stroke Registry (SSR, 2013-2019) and the Stroke InvestiGation in North And central London (SIGNAL) cohort. Patients with nontraumatic, SVD-related ICH and available MRI within 3 months were classified as Cerebral Amyloid angiopathy (CAA), Deep perforator arteriopathy (DPA), Mixed CAA-DPA, or Undetermined SVD using hemorrhagic and nonhemorrhagic MRI markers (CADMUS classification). The primary outcome was inter-rater reliability using Gwet's AC1. Secondary outcomes were recurrent ICH/ischemic stroke at 3 months according to the CADMUS phenotype. We performed Firth penalized logistic regressions and competing risk analyses. RESULTS The SSR cohort included 1,180 patients (median age [interquartile range] 73 [62-80] years, baseline NIH Stroke Scale 6 [2-12], 45.6% lobar hematoma, systolic blood pressure on admission 166 [145-185] mm Hg). The CADMUS phenotypes were as follows: mixed CAA-DPA (n = 751 patients, 63.6%), undetermined SVD (n = 203, 17.2%), CAA (n = 154, 13.1%), and DPA (n = 72, 6.3%), with a similar distribution in the SIGNAL cohort (n = 313). Inter-rater reliability was good (Gwet's AC1 for SSR/SIGNAL 0.69/0.74). During follow-up, 56 patients had 57 events (28 ICH, 29 ischemic strokes). Three-month event rates were comparable between the CADMUS phenotypes. DISCUSSION CADMUS, a novel MRI-based classification for SVD-associated ICH, is feasible and reproducible and may improve the classification of ICH subtypes in clinical practice and research.

Abstract
OBJECTIVE Sex differences regarding the safety and efficacy of carotid revascularization in carotid artery stenosis have been addressed in several studies with conflicting results. Moreover, women are underrepresented in clinical trials, leading to limited conclusions regarding the safety and efficacy of acute stroke treatments. METHODS A systematic review and meta-analysis was performed by literature search including four databases from January 1985 to December 2021. Sex differences in the efficacy and safety of revascularization procedures, including carotid endarterectomy (CEA) and carotid artery stenting (CAS), for symptomatic and asymptomatic carotid artery stenoses were analyzed. RESULTS Regarding CEA in symptomatic carotid artery stenosis, the stroke risk in men (3.6%) and women (3.9%) based on 99,495 patients (30 studies) did not differ (P = .16). There was also no difference in the stroke risk by different time frames up to 10 years. Compared with men, women treated with CEA had a significantly higher stroke or death rate at 4 months (2 studies, 2565 patients; 7.2% vs 5.0%; odds ratio [OR], 1.49; 95% confidence interval [CI], 1.04-2.12; I2 = 0%; P = .03), and a significantly higher rate of restenosis (1 study, 615; 17.2% vs 6.7%; OR, 2.81; 95% CI, 1.66-4.75; P = .0001). For CAS in symptomatic artery stenosis, data showed a non-significant tendency toward higher peri-procedural stroke in women, whereas for asymptomatic carotid artery stenosis, data based on 332,344 patients showed that women (compared with men) after CEA had similar rates of stroke, stroke or death, and the composite outcome stroke/death/myocardial infarction. The rate of restenosis at 1 year was significantly higher in women compared with men (1 study, 372 patients; 10.8% vs 3.2%; OR, 3.71; 95% CI, 1.49-9.2; P = .005). Furthermore, CAS in asymptomatic patients was associated with low risk of a postprocedural stroke in both sexes, but a significantly higher risk of in-hospital myocardial infarction in women than men (8445 patients, 1.2% vs 0.6%; OR, 2.01; 95% CI, 1.23-3.28; I2 = 0%; P = .005). CONCLUSIONS A few sex-differences in short-term outcomes after carotid revascularization for symptomatic and asymptomatic carotid artery stenosis were found, although there were no significant differences in the overall stroke. This indicates a need for larger multicenter prospective studies to evaluate these sex-specific differences. More women, including those aged over 80 years, need to be enrolled in randomized controlled trials, to better understand if sex differences exist and to tailor carotid revascularization accordingly.

Abstract
BACKGROUND Ischaemic stroke may occur despite antiplatelet therapy (APT). We aimed to investigate frequency, potential causes and outcomes in patients with ischaemic stroke despite APT. METHODS In this cohort study, we enrolled patients with imaging-confirmed ischaemic stroke from the Swiss Stroke Registry (01/2014-07/2022). We determined the frequency of prior APT, assessed stroke aetiology (modified TOAST classification) and determined the association of prior APT with unfavourable functional outcome (modified Rankin Scale score 3-6) and recurrent ischaemic stroke at 3 months using regression models. RESULTS Among 53,352 patients, 27,484 (51.5%) had no prior antithrombotic treatment, 17,760 (33.3%) were on APT, 7039 (13.2%) on anticoagulation and 1069 (2.0%) were on APT + anticoagulation. In patients with a history of ischaemic stroke/TIA (n = 11,948; 22.4%), 2401 (20.1%) had no prior antithrombotic therapy, 6594 (55.2%) were on APT, 2489 (20.8%) on anticoagulation and 464 (3.9%) on APT + anticoagulation. Amongst patients with ischaemic stroke despite APT, aetiology was large artery atherosclerosis in 19.8% (n = 3416), cardiac embolism in 23.6% (n = 4059), small vessel disease in 11.7% (n = 2011), other causes in 7.4% (n = 1267), more than one cause in 6.3% (n = 1078) and unknown cause in 31.3% (n = 5388). Prior APT was not independently associated with unfavourable outcome (aOR = 1.06; 95% CI: 0.98-1.14; p = 0.135) or death (aOR = 1.10; 95% CI: 0.99-1.21; p = 0.059) at 3-months but with increased odds of recurrent stroke (6.0% vs 4.3%; aOR 1.26; 95% CI: 1.11-1.44; p < 0.001). CONCLUSIONS One-third of ischaemic strokes occurred despite APT and 20% of patients with a history of ischaemic stroke had no antithrombotic therapy when having stroke recurrence. Aetiology of breakthrough strokes despite APT is heterogeneous and these patients are at increased risk of recurrent stroke.

Abstract
When acute vertigo occurs, the challenge for the medical practitioner lies in the focused assessment to find the cause of its symptoms. Especially in the case of central pathology, a fast diagnosis is essential for therapy. The head impulse, nystagmus, test of skew (HINTS) protocol and the additional video head impulse test (VHIT) can distinguish between central and peripheral vestibular causes in the acute setting and thus help to set the right path for further evaluation and treatment. In this case, a patient with acute onset of vertigo presented with an unusual pattern in the VHIT. Binocular eye tracking showed a disconjugate horizontal vestibulo-ocular reflex (VOR) with severe loss or gain for the adducting eye yet with a lack of corrective saccades. The abducting eye produced a pattern of mild VOR gain loss yet with pronounced corrective saccades. Together with clinical findings that were compatible with internuclear ophthalmoplegia, a probable central lesion in the medial longitudinal fasciculus (MLF) region was suspected. The patient was sent to a tertiary hospital, where the initial MRI was negative, but due to additional neurological symptoms occurring later, multiple lesions in the cervical spine and cerebellum were detected. The hypothesis of an inflammatory demyelinating disease of the central nervous system (CNS) was made. A further workup led to the final diagnosis of neurosarcoidosis. In a retrospective neuroradiologic assessment, an alteration compatible with a non-active demyelinating lesion in the MLF was detected on secondary imaging as a probable cause of the initial pathophysiologic finding. In this report, we aimed to highlight the unusual case of a disconjugate VOR as a distinctive VHIT pattern hinting toward a central cause of acute vertigo that clinicians should be aware of.

Abstract
AIM To compare safety and functional outcomes of intravenous thrombolysis (IVT) between females and males with acute ischaemic stroke (AIS) in relation to preadmission use of antiplatelets. METHODS Multicentre cohort study of patients admitted from 1 January 2014 to 31 January 2020 to hospitals participating in the Swiss Stroke Registry, presenting with AIS and receiving IVT. Primary safety outcome was in-hospital symptomatic intracerebral haemorrhage (sICH). Primary functional outcome was functional independence at 3 months after discharge. Multivariable logistic regression models were fitted to assess the association between sex and each outcome according to preadmission use of antiplatelets. RESULTS The study included 4996 patients (42.51 % females, older than males, median age 79 vs 71 years, p < 0.0001). Comparable proportions of females (39.92 %) and males (40.39 %) used antiplatelets before admission (p = 0.74). In total, 3.06 % females and 2.47 % males developed in-hospital sICH (p = 0.19), with similar odds (adjusted odds ratio, [AOR] 0.93, 95 % confidence interval, [CI] 0.63-1.39). No interaction was found between sex and preadmission use of either single or dual antiplatelets in relation to in-hospital sICH (p = 0.94 and p = 0.23). Males had higher odds of functional independence at 3 months (AOR 1.34, 95 % CI 1.09-1.65), regardless of preadmission use of antiplatelets (interaction between sex and preadmission use of either single or dual antiplatelets p = 0.41 and p = 0.58). CONCLUSION No sex differences were observed in the safety of IVT regarding preadmission use of antiplatelets. Males showed more favourable 3-month functional independence than females; however, this sex difference was apparently not explained by a sex-specific mechanism related to preadmission use of antiplatelets.

Abstract
Introduction:
Endovascular treatment (EVT), in particular mechanical thrombectomy, has dramatically improved the clinical outcome of patients with large vessels occlusion (LVO) of the anterior circulation. In contrast, the benefits of EVT cannot be applied to lacunar strokes (LS). The absence of a LVO in LS has been historically associated with a more favorable outcome, but in the new era of EVT, this assumption may not be correct anymore. We aimed to test the general assumption that LS have a better prognosis than other stroke subtypes, and analyze the outcome of LS treated with IVT as compared to strokes with LVO treated with IVT and/or mechanical thrombectomy in the multicentric Swiss Stroke Registry.
Methods:
retrospective propensity score matching analysis of patients from the Swiss stroke registry (SSR) with lacunar stroke treated with thrombolysis versus LVO of the medial cerebral artery treated with EVT (with or without thrombolysis). Primary endpoint was a shift analysis of mRs at 90 days after stroke. Secondary outcomes were favorable functional outcome (mRS 0-1), independence (mRS 0-2), survival with high disability (mRS 3-5) and mortality (mRS 6) at 90 days.
Results:
From 13'227 patients, the propensity score method matched (sex, age, NIHSS, time to treatment, prior anticoagulation, pre-stroke modified Rankin Score, mRs) 538 patients (269 in each group. There was no difference between groups in mRs shift analysis at 90 days after stroke (OR=0.99, 95%CI=0.73-1.35, p=0.952). There was also no significant difference in mRS 0-1 (59.9% vs 55.8% respectively; OR=0.79, 95%CI=0.55-1.16, p=0.75). LS+IVT patients showed a non-significant trend towards mRS 3-5 (OR=1.23, 95%CI=0.78-1.94, p=0.38), while patients treated with EVT had a slightly, non-significant, higher mortality (6.3% vs 1.9%, p=0.38).
Conclusions:
Lacunar strokes - which cannot directly benefit from thrombectomy therapy - when treated with IVT and matched on key prognostic variables, seem to have similar outcomes as LVO strokes treated with EVT. This observation confirms that lacunar stroke is not a benign entity and therefore suggests that reperfusion therapy should be addressed with the same intensity as LVO stroke.

Abstract
Background and Purpose Knowledge about different etiologies of non-traumatic intracerebral hemorrhage (ICH) and their outcomes is scarce.Methods We assessed prevalence of pre-specified ICH etiologies and their association with outcomes in consecutive ICH patients enrolled in the prospective Swiss Stroke Registry (2014 to 2019). Results We included 2,650 patients (mean±standard deviation age 72±14 years, 46.5% female, median National Institutes of Health Stroke Scale 8 [interquartile range, 3 to 15]). Etiology was as follows: hypertension, 1,238 (46.7%); unknown, 566 (21.4%); antithrombotic therapy, 227 (8.6%); cerebral amyloid angiopathy (CAA), 217 (8.2%); macrovascular cause, 128 (4.8%); other determined etiology, 274 patients (10.3%). At 3 months, 880 patients (33.2%) were functionally independent and 664 had died (25.1%). ICH due to hypertension had a higher odds of functional independence (adjusted odds ratio [aOR], 1.33; 95% confidence interval [CI], 1.00 to 1.77; <i>P</i>=0.05) and lower mortality (aOR, 0.64; 95% CI, 0.47 to 0.86; <i>P</i>=0.003). ICH due to antithrombotic therapy had higher mortality (aOR, 1.62; 95% CI, 1.01 to 2.61; <i>P</i>=0.045). Within 3 months, 4.2% of patients had cerebrovascular events. The rate of ischemic stroke was higher than that of recurrent ICH in all etiologies but CAA and unknown etiology. CAA had high odds of recurrent ICH (aOR, 3.38; 95% CI, 1.48 to 7.69; <i>P</i>=0.004) while the odds was lower in ICH due to hypertension (aOR, 0.42; 95% CI, 0.19 to 0.93; <i>P</i>=0.031).Conclusions Although hypertension is the leading etiology of ICH, other etiologies are frequent. One-third of ICH patients are functionally independent at 3 months. Except for patients with presumed CAA, the risk of ischemic stroke within 3 months of ICH was higher than the risk of recurrent hemorrhage.

Abstract
Background and Purpose Central retinal artery occlusion (CRAO) often leads to permanent monocular blindness. Hence, early recognition and rapid re-perfusion is of paramount importance. This study aims to describe prehospital pathways in CRAO compared to stroke and study the knowledge about CRAO. Methods (1) Description of baseline characteristics, prehospital pathways/delays, and acute treatment (thrombolysis/thrombectomy vs. standard of care) of patients with CRAO and ischemic stroke registered in the Swiss Stroke Registry. (2) Online survey about CRAO knowledge amongst population, general practitioners (GPs) and ophthalmologists in Eastern Switzerland. Results Three hundred and ninety seven CRAO and 32,816 ischemic stroke cases were registered from 2014 until 2019 in 20 Stroke Centers/Units in Switzerland. In CRAO, 25.6% arrived at the hospital within 4 h of symptom onset and had a lower rate of emergency referrals. Hence, the symptom-to-door time was significantly longer in CRAO compared to stroke (852 min. vs. 300 min). The thrombolysis/thrombectomy rate was 13.2% in CRAO and 30.9% in stroke. 28.6% of the surveyed population recognized CRAO-symptoms, 55.4% of which would present directly to the emergency department in contrast to 90.0% with stroke symptoms. Almost 100% of the ophthalmologist and general practitioners recognized CRAO as a medical emergency and 1/3 of them considered IV thrombolysis a potentially beneficial therapy. Conclusions CRAO awareness of the general population and physician awareness about the treatment options as well as the non-standardized prehospital organization, seems to be the main reason for the prehospital delays and impedes treating CRAO patients. Educational efforts should be undertaken to improve awareness about CRAO.

Abstract
Objective To examine rates of intravenous thrombolysis (IVT), mechanical thrombectomy (MT), door‐to‐needle (DTN) time, door‐to‐puncture (DTP) time, and functional outcome between patients with admission magnetic resonance imaging (MRI) versus computed tomography (CT). Methods An observational cohort study of consecutive patients using a target trial design within the nationwide Swiss‐Stroke‐Registry from January 2014 to August 2020 was carried out. Exclusion criteria included MRI contraindications, transferred patients, and unstable or frail patients. Multilevel mixed‐effects logistic regression with multiple imputation was used to calculate adjusted odds ratios with 95% confidence intervals for IVT, MT, DTN, DTP, and good functional outcome (mRS 0–2) at 90 days. Results Of the 11,049 patients included (mean [SD] age, 71 [15] years; 4,811 [44%] women; 69% ischemic stroke, 16% transient ischemic attack, 8% stroke mimics, 6% intracranial hemorrhage), 3,741 (34%) received MRI and 7,308 (66%) CT. Patients undergoing MRI had lower National Institutes of Health Stroke Scale (median [interquartile range] 2 [0–6] vs 4 [1–11]), and presented later after symptom onset (150 vs 123 min, p < 0.001). Admission MRI was associated with: lower adjusted odds of IVT (aOR 0.83, 0.73–0.96), but not with MT (aOR 1.11, 0.93–1.34); longer adjusted DTN (+22 min [13–30]), but not with longer DTP times; and higher adjusted odds of favorable outcome (aOR 1.54, 1.30–1.81). Interpretation We found an association of MRI with lower rates of IVT and a significant delay in DTN, but not in DTP and rates of MT. Given the delays in workflow metrics, prospective trials are required to show that tissue‐based benefits of baseline MRI compensate for the temporal benefits of CT. ANN NEUROL 2022;92:184–194

Abstract
Introduction: Rapid treatment of acute ischemic stroke (AIS) depends on sufficient staffing which differs between Stroke Centers and Stroke Units in Switzerland. We studied the effect of admission time on performance measures of AIS treatment and related temporal trends over time. Patients and methods: We compared treatment rates, door-to-image-time, door-to-needle-time, and door-to-groin-puncture-time in stroke patients admitted during office hours (Monday–Friday 8:00–17:59) and non-office hours at all certified Stroke Centers and Stroke Units in Switzerland, as well as secular trends thereof between 2014 and 2019, using data from the Swiss Stroke Registry. Secondary outcomes were modified Rankin Scale and mortality at 3 months. Results: Data were eligible for analysis in 31,788 (90.2%) of 35,261 patients. Treatment rates for IVT/EVT were higher during non-office hours compared with office hours in Stroke Centers (40.8 vs 36.5%) and Stroke Units (21.8 vs 18.5%). Door-to-image-time and door-to-needle-time increased significantly during non-office hours. Median (IQR) door-to-groin-puncture-time at Stroke Centers was longer during non-office hours compared to office hours (84 (59–116) vs 95 (66–130) minutes). Admission during non-office hours was independently associated with worse functional outcome (1.11 [95%CI: 1.04–1.18]) and increased mortality (1.13 [95%CI: 1.01–1.27]). From 2014 to 2019, median door-to-groin-puncture-time improved and the treatment rate for wake-up strokes increased. Discussion and Conclusion: Despite differences in staffing, patient admission during non-office hours delayed IVT to a similar, modest degree at Stroke Centers and Stroke Units. A larger delay of EVT was observed during non-office hours, but Stroke Centers sped up delivery of EVT over time. Patients admitted during non-office hours had worse functional outcomes, which was not explained by treatment delays.

Abstract
Pregnancy, postpartum and menopause are regarded as periods women are more
vulnerable to ischaemic events. There are conflicting results regarding stroke
risk and hormone replacement therapy (HRT) during menopause. Stroke in pregnancy
is generally increasing with serious consequences for mother and child;
therefore, recommendations for acute treatment with intravenous thrombolysis
(IVT) and/or mechanical thrombectomy (MT) are needed. The aim of this guideline
is to support and guide clinicians in treatment decisions in stroke in women.
Following the “Grading of Recommendations and Assessment, Development and
Evaluation (GRADE)” approach, the guidelines were developed according to the
European Stroke Organisation (ESO) Standard Operating Procedure. Systematic
reviews and metanalyses were performed. Based on available evidence,
recommendations were provided. Where there was a lack of evidence, an expert
consensus statement was given. Low quality of evidence was found to suggest
against the use of HRT to reduce the risk of stroke (ischaemic and haemorrhagic)
in postmenopausal women. No data was available on the outcome of women with
stroke when treated with HRT. No sufficient evidence was found to provide
recommendations for treatment with IVT or MT during pregnancy, postpartum and
menstruation. The majority of members suggested that pregnant women can be
treated with IVT after assessing the benefit/risk profile on an individual
basis, all members suggested treatment with IVT during postpartum and
menstruation. All members suggested treatment with MT during pregnancy. The
guidelines highlight the need to identify evidence for stroke prevention and
acute treatment in women in more vulnerable periods of their lifetime to
generate reliable data for future guidelines.

Abstract
Introduction:
This study aimed to evaluate whether patient sex modifies the association between preadmission use of antiplatelet agents (APAs) and safety and efficacy outcomes of intravenous thrombolysis (IVT) in patients with acute ischemic stroke (AIS).
Methods:
Cohort study from the Swiss Stroke Registry of consecutive patients with AIS treated with IVT stratified according to sex and assessed for preadmission use of APAs in multivariate logistic regression models. The primary safety outcome was in-hospital symptomatic intracerebral haemorrhage (sICH). The primary efficacy outcome was functional independence (FI) at 3 months after discharge. Secondary efficacy outcomes included favourable functional outcome (FFO), modified Rankin Scale score shift analysis, survival with high disability or death at 3 months.
Results:
Study cohort included 4996 patients, 2124 women (43%) and 2872 men (57%). Women were older than men (79 vs 71 years,
P
<0.0001). Comparable proportions of women (39.9%) and men (40.4%) used APAs before admission (single or dual,
P
=0.74). Preadmission use of dual APAs was associated with higher odds of in-hospital sICH (adjOR 2.89, 95%CI 1.15-7.29), with a statistically significant trend from single to dual APAs (
P
=0.02). No interaction was found between preadmission use of either single or dual APAs and patient sex (
P
=0.89 and
P
=0.21, respectively). Men had significantly higher chances of 3-month FI (adjOR 1.34, 95%CI 1.09-1.65), better outcomes across all levels of disability and mortality (adjOR 0.86, 95%CI 0.75-0.99). We found no sex differences in FFO and severe disability or death at 3 months after discharge (adjOR 1.15, 95%CI 0.96-1.36 and adjOR 1.11, 95%CI 0.79-1.55, respectively). We found no interaction between patient sex and preadmission use of either single or dual APAs for any of the secondary efficacy outcomes.
Conclusions:
Female sex was associated with more unfavourable 3-month efficacy outcomes than male sex after IVT. Even though preadmission use of dual APAs was associated with increased odds of in-hospital sICH, sex-gender differences in 3-month efficacy outcomes apparently were not explained by a sex-specific mechanism related to preadmission use of APAs.

Abstract
Background and purpose In Switzerland, the COVID‐19 incidence during the first pandemic wave was high. Our aim was to assess the association of the outbreak with acute stroke care in Switzerland in spring 2020. Methods This was a retrospective analysis based on the Swiss Stroke Registry, which includes consecutive patients with acute cerebrovascular events admitted to Swiss Stroke Units and Stroke Centers. A linear model was fitted to the weekly admission from 2018 and 2019 and was used to quantify deviations from the expected weekly admissions from 13 March to 26 April 2020 (the “lockdown period”). Characteristics and 3‐month outcome of patients admitted during the lockdown period were compared with patients admitted during the same calendar period of 2018 and 2019. Results In all, 28,310 patients admitted between 1 January 2018 and 26 April 2020 were included. Of these, 4491 (15.9%) were admitted in the periods March 13–April 26 of the years 2018–2020. During the lockdown in 2020, the weekly admissions dropped by up to 22% compared to rates expected from 2018 and 2019. During three consecutive weeks, weekly admissions fell below the 5% quantile (likelihood 0.38%). The proportion of intracerebral hemorrhage amongst all registered admissions increased from 7.1% to 9.3% (p = 0.006), and numerically less severe strokes were observed (median National Institutes of Health Stroke Scale from 3 to 2, p = 0.07). Conclusions Admissions and clinical severity of acute cerebrovascular events decreased substantially during the lockdown in Switzerland. Delivery and quality of acute stroke care were maintained.

Abstract
Background Most case series of patients with ischemic stroke (IS) and COVID‐19 are limited to selected centers or lack 3‐month outcomes. The aim of this study was to describe the frequency, clinical and radiological features, and 3‐month outcomes of patients with IS and COVID‐19 in a nationwide stroke registry. Methods From the Swiss Stroke Registry (SSR), we included all consecutive IS patients ≥18 years admitted to Swiss Stroke Centers or Stroke Units during the first wave of COVID‐19 (25 February to 8 June 2020). We compared baseline features, etiology, and 3‐month outcome of SARS‐CoV‐2 polymerase chain reaction‐positive (PCR+) IS patients to SARS‐CoV‐2 PCR− and/or asymptomatic non‐tested IS patients. Results Of the 2341 IS patients registered in the SSR during the study period, 36 (1.5%) had confirmed COVID‐19 infection, of which 33 were within 1 month before or after stroke onset. In multivariate analysis, COVID+ patients had more lesions in multiple vascular territories (OR 2.35, 95% CI 1.08–5.14, p = 0.032) and fewer cryptogenic strokes (OR 0.37, 95% CI 0.14–0.99, p = 0.049). COVID‐19 was judged the likely principal cause of stroke in 8 patients (24%), a contributing/triggering factor in 12 (36%), and likely not contributing to stroke in 13 patients (40%). There was a strong trend towards worse functional outcome in COVID+ patients after propensity score (PS) adjustment for age, stroke severity, and revascularization treatments (PS‐adjusted common OR for shift towards higher modified Rankin Scale (mRS) = 1.85, 95% CI 0.96–3.58, p = 0.07). Conclusions In this nationwide analysis of consecutive ischemic strokes, concomitant COVID‐19 was relatively rare. COVID+ patients more often had multi‐territory stroke and less often cryptogenic stroke, and their 3‐month functional outcome tended to be worse.

Abstract
Background:
We determined the frequency of different etiologies of non-traumatic intracerebral hemorrhage (ICH) and their association with clinical characteristics and outcomes.
Methods:
We analyzed data from consecutive ICH patients enrolled in the prospective Swiss Stroke Registry (2014-2019). Etiology of ICH was determined according to prespecified, mutually exclusive categories. We assessed prevalence of ICH etiologies, their association with clinical characteristics, functional independence (modified Rankin Scale 0-2), mortality, recurrent ICH and ischemic stroke at 3 months.
Results:
We included 2584 patients (median age 72y, IQR 64-82, 46.6% female, median NIHSS 10; IQR 3-15). 2037 patients (80%) had hypertension and 553 (22.3%) were on anticoagulants. Distribution of etiologies was as follows: Hypertension (n=1216 patients; 47.1% of all / 56.3% of patients with hypertension), unknown etiology (n=542, 21.0%), antithrombotic therapy (n=225, 8.7% of all / 38% of patients on anticoagulants), cerebral amyloid angiopathy (CAA, n=211, 8.2%), macro-vascular (n=121, 4.7%), other determined etiologies (n=269, 10.4%). Patients with hypertensive ICH had significantly higher NIHSS (median 9; IQR 4-16) and blood pressure levels (median systolic 176; IQR 156-195) on admission. Patients with CAA had significantly lower NIHSS at baseline (median 5; IQR 2-12). Three month follow-up was available for 2109/2584 patients (81.6%). 820 (38.9%) were functionally independent, 658 have died (31.2%). Hypertensive ICH was associated with an increased rate of functional independence (aOR =1.42, 95%CI 1.06-1.90, p=0.02). 5.2% of patients had a cerebrovascular event within 3 months. CAA was associated with a high risk of recurrent ICH (HR 6.95, 95%CI 3.05-15.84, p<0.001). The risk of ischemic stroke (2.2%) was higher than that of ICH (1.5%) in patients with hypertensive ICH.
Conclusions:
In Swiss Stroke Units and Centers, one of two patients has ICH from a different cause than hypertension. The rate of functionally independent patients at 3 months seems higher than mortality. Absolute and relative risks of recurrent ICH and ischemic stroke after recent ICH differ among underlying etiologies.

Abstract
OBJECTIVE The aim was to evaluate, in patients with atrial fibrillation (AF) and acute ischemic stroke, the association of prior anticoagulation with vitamin K antagonists (VKAs) or direct oral anticoagulants (DOACs) with stroke severity, utilization of intravenous thrombolysis (IVT), safety of IVT, and 3-month outcomes. METHODS This was a cohort study of consecutive patients (2014-2019) on anticoagulation versus those without (controls) with regard to stroke severity, rates of IVT/mechanical thrombectomy, symptomatic intracranial hemorrhage (sICH), and favorable outcome (modified Rankin Scale score 0-2) at 3 months. RESULTS Of 8,179 patients (mean [SD] age, 79.8 [9.6] years; 49% women), 1,486 (18%) were on VKA treatment, 1,634 (20%) on DOAC treatment at stroke onset, and 5,059 controls. Stroke severity was lower in patients on DOACs (median National Institutes of Health Stroke Scale 4, [interquartile range 2-11]) compared with VKA (6, [2-14]) and controls (7, [3-15], p < 0.001; quantile regression: β -2.1, 95% confidence interval [CI] -2.6 to -1.7). The IVT rate in potentially eligible patients was significantly lower in patients on VKA (156 of 247 [63%]; adjusted odds ratio [aOR] 0.67; 95% CI 0.50-0.90) and particularly in patients on DOACs (69 of 464 [15%]; aOR 0.06; 95% CI 0.05-0.08) compared with controls (1,544 of 2,504 [74%]). sICH after IVT occurred in 3.6% (2.6-4.7%) of controls, 9 of 195 (4.6%; 1.9-9.2%; aOR 0.93; 95% CI 0.46-1.90) patients on VKA and 2 of 65 (3.1%; 0.4-10.8%, aOR 0.56; 95% CI 0.28-1.12) of those on DOACs. After adjustments for prognostic confounders, DOAC pretreatment was associated with a favorable 3-month outcome (aOR 1.24; 1.01-1.51). INTERPRETATION Prior DOAC therapy in patients with AF was associated with decreased admission stroke severity at onset and a remarkably low rate of IVT. Overall, patients on DOAC might have better functional outcome at 3 months. Further research is needed to overcome potential restrictions for IVT in patients taking DOACs. ANN NEUROL 2021;89:42-53.

Abstract
Background and Purpose: To identify factors associated with prior stroke at presentation in patients with cryptogenic stroke (CS) and patent foramen ovale (PFO). Methods: We studied cross-sectional data from the International PFO Consortium Study (NCT00859885). Patients with first-ever stroke and those with prior stroke at baseline were analyzed for an association with PFO-related (right-to-left shunt at rest, atrial septal aneurysm, deep venous thrombosis, pulmonary embolism, and Valsalva maneuver) and PFO-unrelated factors (age, gender, BMI, hypertension, diabetes mellitus, hypercholesterolemia, smoking, migraine, coronary artery disease, aortic plaque). A multivariable analysis was used to adjust effect estimation for confounding, e.g., owing to the age-dependent definition of study groups in this cross-sectional study design. Results: We identified 635 patients with first-ever and 53 patients with prior stroke. Age, BMI, hypertension, diabetes mellitus, hypercholesterolemia, coronary artery disease, and right-to-left shunt (RLS) at rest were significantly associated with prior stroke. Using a pre-specified multivariable logistic regression model, age (Odds Ratio 1.06), BMI (OR 1.06), hypercholesterolemia (OR 1.90) and RLS at rest (OR 1.88) were strongly associated with prior stroke.Based on these factors, we developed a nomogram to illustrate the strength of the relation of individual factors to prior stroke. Conclusion: In patients with CS and PFO, the likelihood of prior stroke is associated with both, PFO-related and PFO-unrelated factors.

Abstract
BACKGROUND: Plaque vulnerability plays an important role in determining the risk of subsequent cerebrovascular events in patients with carotid stenosis. Plaque morphology magnetic resonance imaging (MRI) can be used to assess plaque vulnerability. We therefore set out to examine the diagnostic accuracy of plaque morphology MRI compared with histopathological findings as gold standard in moderate- to high-grade carotid stenosis at our centre. METHODS A total of 36 patients with moderate- to high-grade carotid stenosis underwent plaque morphology MRI with a multisequence protocol (time of flight sequence, dark blood T1- [native and post-gadolinium] and T2-weighted sequence with fat suppression). The status of the fibrous cap, calcification, lipid-rich necrotic core (LRNC) and intraplaque haemorrhage (IPH) were assessed by means of qualitative MR analysis of plaque characteristics and compared with the histopathological findings. Detection statistics (sensitivity, specificity), chi-squared test, Cohen’s kappa (κ), percentage of agreement and phi coefficient (φ) were determined. RESULTS Carotid stenosis was symptomatic (transient ischaemic attack, amaurosis fugax or ischaemic stroke in the territory of the stenosed carotid artery) in 25 patients (69.5%). Twenty-eight patients (77.8%) had a high-grade and eight patients (12.2%) a moderate-grade stenosis. Significant congruence between MRI and histology was found for plaque calcification (89% histology, 75% MRI, κ = 0.364, p = 0.013), for LRNC (89% histology, 53% MRI, κ = 0.245, p = 0.025) and IPH (75% histology, 53% MRI, κ = 0.314, p = 0.035). In a subgroup of patients with symptomatic stenosis, the agreement for LRNC and IPH was slightly better (LRNC κ = 0.390, p = 0.014; IPH κ = 0.386, p = 0.045). Status of the fibrous cap, essentially ulceration, did not show any significant agreement (κ = 0.032, p = 0.842). There was significant correlation between LRNC on MRI and symptomatic carotid stenosis (φ = 0.339, p = 0.042). CONCLUSION Plaque morphology MRI is capable of identifying the main components of atherosclerotic plaques with moderate to good accuracy as compared with histopathological findings as gold standard. LRNC seems to be a useful marker of plaque vulnerability and warrants its use in clinical decision making.  .

Abstract
Background Primary Sjögren’s syndrome is the second most common rheumatological disorder after rheumatoid arthritis. It typically presents as xerophthalmia and xerostomia in postmenopausal women. Involvement of the central nervous system has been recognized, although its pathogenesis and characteristics are poorly understood. Central nervous system complications are a diagnostic challenge and emphasize the need for systematic screening of patients with new peripheral and central neurological symptoms. Case report We report a case of a 58-year-old Swiss woman presenting with rapidly progressive sensorimotor distal polyneuropathy together with new-onset generalized seizures. Initial magnetic resonance imaging (MRI) of the brain performed after the first seizure showed multiple, bihemispheric, confluent white matter hyperintensities with contrast enhancement. Follow-up imaging 3 days after the initial magnetic resonance imaging demonstrated a fulminant disease progression associated with the serious clinical deterioration of the patient. In light of the results of a minor salivary gland biopsy, autoantibody testing, nerve conduction studies, and cranial magnetic resonance imaging, primary Sjögren’s syndrome with cryoglobulinemia type II was diagnosed. Response to plasmapheresis and subsequent administration of cyclophosphamide was favorable. Conclusion Even though exocrinopathy is the hallmark of Sjögren’s syndrome, systemic symptoms are observed in one-third of patients. There is an urgent need to better characterize the mechanisms underlying different disease phenotypes and to perform randomized controlled trials in order to provide tailored and evidence-based treatment for primary Sjögren’s syndrome.

Abstract
Background Recent randomized controlled trial (RCTs) comparing percutaneous closure with antithrombotic treatment in patients with patent foramen ovale (PFO) and cryptogenic stroke revealed inconsistent results. Indeed, there is still no consensus on the management of these patients, namely closure or medical therapy treatment. Methods To take stock of the PFO management after cryptogenic stroke, we conducted a literature review that included 16 articles dealing with different therapeutic strategies and long-term outcomes of these results. Results The reviewed studies showed great methodological diversity rendering an exhaustive and balanced comparison between studies difficult. Low recurrence rates under prevention regimens, crossovers, procedure- and device-related complications, as well as inappropriate patient selection might explain the inconsistency of trials. However, despite the methodological heterogeneity certain patterns could be detected. It appears that device closure as secondary prevention measure is an effective and safe procedure reducing the recurrence of neurological events in cryptogenic stroke patients <60 years with large PFOs. Standardization of procedures and larger trials are needed to arrive to definitive conclusions. Conclusion In cryptogenic stroke patients <60 years with large PFOs, PFO closure seems to be safe and more effective compared to medical treatment alone. For all other patients group, for example, patients >60 years further trials are needed to clarify the role of PFO closure.

Abstract
BACKGROUND AND PURPOSE Randomized controlled trials have shown that mechanical thrombectomy (MT) plus best medical treatment improves outcome in stroke patients with large-vessel occlusion in the anterior circulation. Whether direct MT is equally effective as bridging thrombolysis (intravenous thrombolysis plus MT) in intravenous thrombolysis eligible patients remains unclear. METHODS We compared clinical and radiological outcomes at 3 months in 249 bridging patients with 111 patients receiving direct MT for large-vessel occlusion anterior circulation stroke from 2 prospective registries (study period Essen: June 2012 to August 2013, Bern February 2009 to August 2014). We matched all patients from the direct MT group who would have qualified for intravenous thrombolysis with controls from the bridging group, using multivariate and propensity score methods. Subgroup analyses for internal carotid artery occlusions were performed. RESULTS Baseline characteristics did not differ between the direct MT group and bridging cohort, except for higher rates of coronary heart disease (P=0.029) and shorter intervals from onset to endovascular therapy (P<0.001) in the MT group. Functional outcome, mortality, and intracerebral hemorrhage did not differ, neither in univariate nor after multivariate and propensity score matching. However, in patients with internal carotid artery occlusion, mortality in the direct cohort was significantly lower. CONCLUSIONS In this matched-pair analysis, there was no difference in outcome in patients with large-vessel occlusion anterior circulation stroke treated with direct MT compared with those treated with bridging thrombolysis; however, mortality in patients with internal carotid artery occlusion treated with direct MT was significantly lower than after bridging thrombolysis. Randomized trials comparing direct MT with bridging therapy are needed.

Abstract
Background and purpose Some authors use FLAIR imaging to select patients for stroke treatment. However, the effect of hyperintensity on FLAIR images on outcome and bleeding has been addressed in only few studies with conflicting results. Methods 466 patients with anterior circulation strokes were included in this study. They all were examined with MRI before intravenous or endovascular treatment. Baseline data and 3 months outcome were recorded prospectively. Focal T2 and FLAIR hyperintensities within the ischemic lesion were evaluated by two raters, and the PROACT II classification was applied to assess bleeding complications on follow up imaging. Logistic regression analysis was used to determine predictors of bleeding complications and outcome and to analyze the influence of T2 or FLAIR hyperintensity on outcome. Results Focal hyperintensities were found in 142 of 307 (46.3%) patients with T2 weighted imaging and in 89 of 159 (56%) patients with FLAIR imaging. Hyperintensity in the basal ganglia, especially in the lentiform nucleus, on T2 weighted imaging was the only independent predictor of any bleeding after reperfusion treatment (33.8% in patients with vs. 18.2% in those without; p = 0.003) and there was a non-significant trend for more bleedings in patients with FLAIR hyperintensity within the basal ganglia (p = 0.069). However, there was no association of hyperintensity on T2 weighted or FLAIR images and symptomatic bleeding or worse outcome. Conclusion Our results question the assumption that T2 or FLAIR hyperintensities within the ischemic lesion should be used to exclude patients from reperfusion therapy, especially not from endovascular treatment.

Abstract
OBJECTIVE Spinal CSF leakage causes spontaneous intracranial hypotension (SIH). The aim of this study was to characterize CSF dynamics via lumbar infusion testing in patients with and without proven spinal CSF leakage in order to explore possible discriminators for the presence of an open CSF leak. METHODS This analysis included all patients with suspected SIH who were treated at the authors' institution between January 2012 and February 2015. The gold standard for "proven" CSF leakage is considered to be extrathecal contrast accumulation after intrathecal contrast injection. To characterize CSF dynamics, the authors performed computerized lumbar infusion testing to measure lumbar pressure at baseline (opening pressure) and at plateau, as well as pulse amplitude, CSF outflow resistance (RCSF), craniospinal elastance, and pressure-volume index. RESULTS Thirty-one patients underwent clinical imaging and lumbar infusion testing and were included in the final analysis. A comparison of the 14 patients with proven CSF leakage with the 17 patients without leakage showed a statistically significantly lower lumbar opening pressure (p < 0.001), plateau pressure (p < 0.001), and RCSF (p < 0.001) in the group with leakage. Sensitivity, specificity, and positive and negative predictive values for an RCSF cutoff of ≤ 5 mm Hg/(ml/min) were 0.86, 1.0, 1.0, and 0.89 (area under the curve of 0.96), respectively. The median pressure-volume index was higher (p = 0.003), and baseline (p = 0.017) and plateau (p < 0.001) pulse amplitudes were lower in patients with a proven leak. CONCLUSIONS Lumbar infusion testing captures a distinct pattern of CSF dynamics associated with spinal CSF leakage. RCSF assessed by computerized lumbar infusion testing has an excellent diagnostic accuracy and is more accurate than evaluating the lumbar opening pressure. The authors suggest inclusion of RCSF in the diagnostic criteria for SIH.

Abstract
BACKGROUND AND PURPOSE Intravenous thrombolysis (IVT) within 4.5 hours from symptom onset improves functional outcome in patients with acute ischemic stroke. Its use in patients with previous stroke within the preceding 3 months is contraindicated because of the assumed higher risk of intracranial hemorrhage. In addition, tissue-type plasminogen activator may itself promote neurotoxicity and blood-brain barrier disruption. However, safety and effectiveness of repeated IVT is essentially unknown in patients with early (<3 months) recurrent stroke (ERS), because they were excluded from thrombolysis trials. This article reports the largest case series of repeated IVT in ERS. METHODS We reviewed databases of prospectively collected patient data of 8 European stroke centers for the presence of patients with ERS, who received IVT for both the index stroke and ERS. Demographics, clinical and radiological data, bleeding complications, and functional outcome were analyzed. RESULTS We identified 19 subjects with repeated IVT in ERS. Mean age was 68±12 years, and 37% of them were female. Median interthrombolysis interval was 30 days (interquartile range, 13-50). Functional independence (modified Rankin scale score ≤2) was achieved in 79% of patients after the first and in 47.4% after repeated IV tissue-type plasminogen activator, respectively. There was no symptomatic intracranial hemorrhage. Median final infarct volume after the first IVT was 1.5 cm(3) (interquartile range, 0.5-3.1). CONCLUSIONS Patients with small infarct volumes and robust clinical improvement might be considered for repeated IVT within 3 months. Studies following strict protocols and larger registries incorporating these patients might serve to identify selection criteria for the safe use of repeated IVT in ERS.

Abstract
Background:
In patients with cryptogenic stroke (CS), a patent foramen ovale (PFO) can be incidental or pathogenic. The Risk of Paradoxical Embolism (RoPE) score has been developed to determine the likelihood that a PFO is pathogenic or incidental using clinical variables. We hypothesize that echocardiographic features and conditions promoting paradoxical embolism differ between patients with pathogenic and incidental PFOs.
Methods:
The International PFO Consortium collects clinical, radiological and echocardiographic data of patients with CS and PFO. In the original RoPE score, a value of 0-6 was classified as a low RoPE score and 7-10 as a high score. Since information on cortical versus deep stroke location (one of the items on the RoPE score) was not available, we used two alternative approaches to stratify for PFO pathogenicity. In a first approach, we used a 9-point score and lowered the cut-off for dichotomization by 1 point (RoPE score 0-5 vs 6-9). In a second approach, patients with a RoPE score of 6 were excluded since they could either be classified as low or high RoPE score depending on stroke location. The associations between RoPE stratum and echocardiographic features (atrial septal aneurysm (ASA), right-to-left shunt (RLS) at rest and large RLS) as well as conditions promoting paradoxical embolism (deep vein thrombosis (DVT), pulmonary embolism (PE) and Valsalva maneuver (VM) were studied.
Results:
We analyzed 1044 CS patients with a PFO. Average age was 55 (SD 16) and 635 patients (61%) were male. Preceding VM was more frequent in patients with a high vs low RoPE score in both analyses: 11% vs 5% (OR: 2.1 95%CI 1.3-4.3) and 10% vs 5% (OR: 2.0 95%CI 1.2-3.6). The distribution of ASA (35% vs 34% and 32% vs 34%, in the first and the second analysis respectively), RLS at rest (28% vs 28% and 29% vs 28%), large RLS (67% vs 66% and 65% vs 66%), PE (2% vs 2% and 1% vs 2%), and DVT (4% vs 4% and 3% vs 4%) did not differ by RoPE stratum.
Conclusion:
In patients with CS, preceding VM was significantly associated with pathogenic PFO, while echocardiographic features or conditions promoting paradoxical embolism were not. The formation of a significant right-to-left pressure gradient at the atrial septum level appears to play a substantial role in the pathogenicity of PFO.

Abstract
Background:
A patent foramen ovale (PFO) discovered in patients with cryptogenic stroke (CS) may be incidental or pathogenic. Recently, a Risk of Paradoxical Embolism (RoPE) score has been proposed to stratify patients by their PFO pathogenicity. Based on this score, the probability that a PFO is incidental (rather than pathogenic) increases with advancing age, deep stroke location, or the presence of cardiovascular risk factors (RF). Given that RF accumulate at a later age in women than in men, we hypothesize that there are gender differences in the variables used for RoPE score calculation.
Methods:
The distribution of RF (history of hypertension, diabetes or stroke/TIA, current smoking, and age categories as defined in the original RoPE score publication) was compared by sex in the entire cohort of 1044 CS patients as well as within the groups with low (0-5) and high (7-10) RoPE scores (due to lacking information on cortical versus deep stroke location, we excluded all patients with a RoPE score of 6, since they could be either classified with low or high RoPE score depending on stroke location). Furthermore, for each patient we calculated the age impact ratio (AIR): the points assigned for the corresponding age category divided by the RoPE score. Gender comparisons of AIR were drawn in the entire cohort and within the RoPE score strata.
Results:
Average age was 55.5 years and 635 patients (61%) were male. In the entire cohort, the distribution of age categories and RF as well as AIR did not differ between men and women. In the higher RoPE stratum (PFO likely pathogenic), women were younger than men (median, 38 years vs 45 years, P=0.036). The distribution of RF and the AIR did not differ between sexes. In the lower PFO stratum (PFO likely incidental), men were younger than women (median, 62 years vs 66 years, P=0.011). The AIR was lower in women than in men (mean, 0.24 vs 0.29, P=0.013). There were no gender differences in the distribution of RF.
Conclusions:
There are significant gender differences in age among patients with CS and PFO, with women being younger than men in the higher RoPE stratum and vice versa in the lower RoPE stratum. More women than men are classified as having an incidental PFO because of their advancing age rather than the accumulation of RF.

Abstract
BACKGROUND The aim of this study was to analyze the influence of the location of middle cerebral artery (MCA) occlusion on recanalization, complications and outcome after endovascular therapy. METHODS Four-hundred sixty-four patients with acute MCA occlusions were treated with endovascular therapy. RESULTS Two-hundred ninety-three patients had M1 occlusions, 116 had M2, and 55 had M3/4 occlusions. Partial or complete recanalization was more frequently achieved in M1 (76.8%) than in M2 (59.1%) or M3/4 (47.3%, p < 0.001) occlusions, but favorable outcome (modified Rankin Scale 0-2) was less frequent in M1 (50.9%) than M2 (63.7%) or M3/4 (72.7%, p = 0.018) occlusions. Symptomatic intracerebral hemorrhage (ICH) did not differ between occlusion sites, but asymptomatic ICH was more common in M1 (22.6%) than in M2 occlusions (8.6%, p = 0.003). Recanalization was associated with favorable outcome in M1 (p < 0.001) and proximal M2 (p = 0.003) but not in distal M2 or M3/4 occlusions. CONCLUSIONS Recanalization with endovascular therapy was more frequently achieved in patients with proximal than distal MCA occlusions, but recanalization was associated with favorable outcome only in M1 and proximal M2 occlusions. Outcome was better with distal than proximal occlusions. This study shows that recanalization can be used as a surrogate marker for clinical outcome only in patients with proximal occlusions.

Abstract
BACKGROUND AND PURPOSE Lesion volume on diffusion-weighted magnetic resonance imaging (DWI) before acute stroke therapy is a predictor of outcome. Therefore, patients with large volumes are often excluded from therapy. The aim of this study was to analyze the impact of endovascular treatment in patients with large DWI lesion volumes (>70 mL). METHODS Three hundred seventy-two patients with middle cerebral or internal carotid artery occlusions examined with magnetic resonance imaging before treatment since 2004 were included. Baseline data and 3 months outcome were recorded prospectively. DWI lesion volumes were measured semiautomatically. RESULTS One hundred five patients had lesions >70 mL. Overall, the volume of DWI lesions was an independent predictor of unfavorable outcome, survival, and symptomatic intracerebral hemorrhage (P<0.001 each). In patients with DWI lesions >70 mL, 11 of 31 (35.5%) reached favorable outcome (modified Rankin scale score, 0-2) after thrombolysis in cerebral infarction 2b-3 reperfusion in contrast to 3 of 35 (8.6%) after thrombolysis in cerebral infarction 0-2a reperfusion (P=0.014). Reperfusion success, patient age, and DWI lesion volume were independent predictors of outcome in patients with DWI lesions >70 mL. Thirteen of 66 (19.7%) patients with lesions >70 mL had symptomatic intracerebral hemorrhage with a trend for reduced risk with avoidance of thrombolytic agents. CONCLUSIONS There was a growing risk for poor outcome and symptomatic intracerebral hemorrhage with increasing pretreatment DWI lesion volumes. Nevertheless, favorable outcome was achieved in every third patient with DWI lesions >70 mL after successful endovascular reperfusion, whereas after poor or failed reperfusion, outcome was favorable in only every 12th patient. Therefore, endovascular treatment might be considered in patients with large DWI lesions, especially in younger patients.

Abstract
PURPOSE Assessment of the cerebral blood flow (CBF) is crucial in the evaluation of patients with steno-occlusive diseases of the arteries supplying the brain for prediction of stroke risk. Quantitative phase contrast magnetic resonance angiography (PC-MRA) can be utilised for noninvasive quantification of CBF. The aim of this study was to validate in-vivo PC-MRA data by comparing them with colour-coded duplex (CCD) sonography in patients with cerebrovascular disease. METHODS AND MATERIALS We examined 24 consecutive patients (mean age 63 years) with stenosis of arteries supplying the brain using PC-MRA and CCD. Velocities were measured in a total of 209 stenotic and healthy arterial segments (110 extra- and 99 intracranial). RESULTS Moderate to good correlation of velocity measurements between both techniques was observed in all six extracranial and five out of seven intracranial segments (p <0.05). Velocities measured with CCD sonography were generally higher than those obtained by PC-MRA. Reversal of flow direction was detected consistently with both methods. CONCLUSION PC-MRA represents a robust, standardised magnetic resonance imaging technique for blood flow measurements within a reasonable acquisition time, potentially evolving as valuable work-up tool for more precise patient stratification for revascularisation therapy. PC-MRA overcomes relevant weaknesses of CCD in being not operator-dependent and not relying on a bone window to assess the intracranial arteries.

Abstract
BACKGROUND AND PURPOSE The use of thrombolysis in patients with minor neurological deficits and large vessel occlusion is controversial. METHODS We compared the outcome of patients with low National Institutes of Health Stroke Scale (NIHSS) scores and large vessel occlusions between thrombolysed and non-thrombolysed patients. RESULTS 88 (1.7%) of 5312 consecutive patients with acute (within 24 h) ischaemic stroke had occlusions of the internal carotid or the main stem of the middle cerebral artery and baseline NIHSS scores ≤5.47 (53.4%) were treated without thrombolysis, and 41 (46.6%) received intravenous thrombolysis, endovascular therapy or both. Successful recanalisation on MR or CT angiography at 24 h was more often observed in thrombolysed than in non-thrombolysed patients (78.9% versus 10.5%; p<0.001). Neurological deterioration (increase of NIHSS score ≥1 compared to baseline) was observed in 22.7% of non-thrombolysed versus 10.3% of thrombolysed after 24 h (p=0.002), in 33.3% versus 12.5% at hospital discharge (p=0.015) and in 41.4% versus 15% at 3 months (p<0.001). Symptomatic intracerebral haemorrhage occurred in two (asymptomatic in five) thrombolysed and in none (asymptomatic in three) non-thrombolysed. Thrombolysis was an independent predictor of favourable outcome (p=0.030) but not survival (p=0.606) at 3 months. CONCLUSIONS Non-thrombolysed patients with mild deficits and large vessel occlusion deteriorated significantly more often within 3 months than thrombolysed patients. Symptomatic intracerebral haemorrhages occurred in less than 5% of patients in both groups. These data suggest that thrombolysis is safe and effective in these patients. Therefore, randomised trials in patients with large vessel occlusions and mild or rapidly improving symptoms are needed.

Abstract
Ischaemic stroke (IS) in young adults has been increasingly recognized as a serious health condition. Stroke aetiology is different in young adults than in the older population. This study aimed to investigate aetiology and risk factors, and to search for predictors of outcome and recurrence in young IS patients. We conducted a prospective multicentre study of consecutive IS patients aged 16-55 years. Baseline demographic data, risk factors, stroke aetiology including systematic genetic screening for Fabry disease and severity were assessed and related to functional neurological outcome (modified Rankin Scale, mRS), case fatality, employment status, place of residence, and recurrent cerebrovascular events at 3 months. In 624 IS patients (60% men), median age was 46 (IQR 39-51) years and median NIHSS on admission 3 (IQR 1-8). Modifiable vascular risk factors were found in 73%. Stroke aetiology was mostly cardioembolism (32%) and of other defined origin (24%), including cervicocerebral artery dissection (17%). Fabry disease was diagnosed in 2 patients (0.3%). Aetiology remained unknown in 20%. Outcome at 3 months was favourable (mRS 0-1) in 61% and fatal in 2.9%. Stroke severity (p < 0.001) and diabetes mellitus (p = 0.023) predicted unfavourable outcome. Stroke recurrence rate at 3 months was 2.7%. Previous stroke or TIA predicted recurrent cerebrovascular events (p = 0.012). In conclusion, most young adults with IS had modifiable vascular risk factors, emphasizing the importance of prevention strategies. Outcome was unfavourable in more than a third of patients and was associated with initial stroke severity and diabetes mellitus. Previous cerebrovascular events predicted recurrent ones.

Abstract
Background and purpose:
Recurrent ischemic stroke in patients with CS and PFO has been proposed as a marker of increased risk for paradoxical embolism. It is unclear, whether the excess risk is driven by specific features of the PFO (right-to-left shunt (RLS) size, RLS at rest, associated atrial septum aneurysm (ASA)) or the presence of vascular risk factors (vRF). We compare the prevalence of vRF, TEE features, and baseline medications in PFO patients with first-ever versus multiple CS.
Methods:
From September 2008 to March 2013, the International PFO Consortium enrolled 993 patients with ischemic stroke or transient ischemic attack (TIA) and newly diagnosed PFO. In this analysis of baseline data, we included 386 patients with first-ever CS and no radiological evidence of prior cerebral ischemia (first-ever CS group, mean age, 52y) as well as 71 patients with recurrent CS and multiple ischemic lesions on CT and/or MRI (multiple CS group, mean age, 59y). Patients with TIA as index event, those with first-ever CS but additional “silent” ischemic lesions on imaging as well as those with recurrent CS without radiological findings of prior cerebral ischemia were excluded. We used nonparametric tests for independent samples and the Bonferroni correction for multiple comparisons.
Results:
Age > 55y (63% vs. 44%, P=0.001), hypertension (52% vs. 30%, P=0.001), hyperlipidemia (64% vs. 44%, P=0.003), and coronary artery disease (15% vs. 3%, P=0.001) were significantly more frequent in the multiple CS than in the first-ever CS group. The frequencies of male gender, current smoking, diabetes, migraine with or without aura, associated ASA, RLS size, and RLS at rest did not differ between groups. At baseline, patients with multiple CS were more likely to be on antiplatelets (50% vs. 18%), antihypertensive (51% vs. 22%) or lipid lowering drugs (44% vs. 10%, P=0.001 for each comparison) than patients with first-ever CS. The frequency of anticoagulant treatment did not differ between groups.
Conclusions:
In patients with CS, vRF but not specific PFO features were associated with recurrent cerebral ischemic events. The ongoing prospective part of the International PFO Consortium will likely shed light upon the role of vRF control for secondary stroke prevention in patients with PFO.

Abstract
OBJECTIVE We examined the influence of clinical, radiologic, and echocardiographic characteristics on antithrombotic choice in patients with cryptogenic stroke (CS) and patent foramen ovale (PFO), hypothesizing that features suggestive of paradoxical embolism might lead to greater use of anticoagulation. METHODS The Risk of Paradoxical Embolism Study combined 12 databases to create the largest dataset of patients with CS and known PFO status. We used generalized linear mixed models with a random effect of component study to explore whether anticoagulation was preferentially selected based on the following: (1) younger age and absence of vascular risk factors, (2) "high-risk" echocardiographic features, and (3) neuroradiologic findings. RESULTS A total of 1,132 patients with CS and PFO treated with anticoagulation or antiplatelets were included. Overall, 438 participants (39%) were treated with anticoagulation with a range (by database) of 22% to 54%. Treatment choice was not influenced by age or vascular risk factors. However, neuroradiologic findings (superficial or multiple infarcts) and high-risk echocardiographic features (large shunts, shunt at rest, and septal hypermobility) were predictors of anticoagulation use. CONCLUSION Both antithrombotic regimens are widely used for secondary stroke prevention in patients with CS and PFO. Radiologic and echocardiographic features were strongly associated with treatment choice, whereas conventional vascular risk factors were not. Prior observational studies are likely to be biased by confounding by indication.

Abstract
OBJECTIVE To examine predictors of stroke recurrence in patients with a high vs a low likelihood of having an incidental patent foramen ovale (PFO) as defined by the Risk of Paradoxical Embolism (RoPE) score. METHODS Patients in the RoPE database with cryptogenic stroke (CS) and PFO were classified as having a probable PFO-related stroke (RoPE score of >6, n = 647) and others (RoPE score of ≤6 points, n = 677). We tested 15 clinical, 5 radiologic, and 3 echocardiographic variables for associations with stroke recurrence using Cox survival models with component database as a stratification factor. An interaction with RoPE score was checked for the variables that were significant. RESULTS Follow-up was available for 92%, 79%, and 57% at 1, 2, and 3 years. Overall, a higher recurrence risk was associated with an index TIA. For all other predictors, effects were significantly different in the 2 RoPE score categories. For the low RoPE score group, but not the high RoPE score group, older age and antiplatelet (vs warfarin) treatment predicted recurrence. Conversely, echocardiographic features (septal hypermobility and a small shunt) and a prior (clinical) stroke/TIA were significant predictors in the high but not low RoPE score group. CONCLUSION Predictors of recurrence differ when PFO relatedness is classified by the RoPE score, suggesting that patients with CS and PFO form a heterogeneous group with different stroke mechanisms. Echocardiographic features were only associated with recurrence in the high RoPE score group.

Abstract
Elderly patients generally experience less favorable outcomes and higher mortality after acute stroke than younger patients. The aim of this study was to analyze the influence of age on outcome and safety after endovascular therapy in a large cohort of patients aged between 20 and 90 years. We prospectively acquired data of 1,000 stroke patients treated with endovascular therapy at a single center. Logistic regression analysis was performed to determine predictors of outcome and linear regression analysis to evaluate the association of age and outcome after 3 months. Younger age was an independent predictor of favorable outcome (OR 0.954, p < 0.001) and survival (OR 0.947, p < 0.001) in multivariate regression analysis. There was a linear relationship between age and outcome. Ever increase in 26 years of age was associated with an increase in the modified Rankin Scale of 1 point (p < 0.001). However, increasing age was not a risk factor for symptomatic (p = 0.086) or asymptomatic (p = 0.674) intracerebral hemorrhage and did not influence recanalization success (p = 0.674). Advancing age was associated with a decline of favorable outcomes and survival after endovascular therapy. This decline was linear from age 20 to 90 years, but was not related to lower recanalization rates or higher bleeding risk in the elderly. The efficacy of endovascular stroke therapy seems to be preserved also in the elderly and other factors than efficacy of endovascular therapy such as decreased plasticity are likely to explain the worse outcome with advancing age.

Abstract
Object
The risk of recurrence of cerebrovascular events within the first 72 hours of admission in patients hospitalized with symptomatic carotid artery (CA) stenoses and the risks and benefits of emergency CA intervention within the first hours after the onset of symptoms are not well known. Therefore, the authors aimed to assess 1) the ipsilateral recurrence rate within 72 hours of admission, in the period from 72 hours to 7 days, and after 7 days in patients presenting with nondisabling stroke, transient ischemic attack (TIA), or amaurosis fugax (AF), and with an ipsilateral symptomatic CA stenosis of 50% or more, and 2) the risk of stroke in CA interventions within 48 hours of admission versus the risk in interventions performed after 48 hours.
Methods
Ninety-four patients were included in this study. These patients were admitted to hospital within 48 hours of a nondisabling stroke, TIA, or AF resulting from a symptomatic CA stenosis of 50% or more. The patients underwent carotid endarterectomy (85 patients) or CA stenting (9 patients). At baseline, the cardiovascular risk factors of the patients, the degree of symptomatic CA stenosis, and the type of secondary preventive treatment were assessed. The in-hospital recurrence rate of stroke, TIA, or AF ipsilateral to the symptomatic CA stenosis was determined for the first 72 hours after admission, from 72 hours to 7 days, and after 7 days. Procedure-related cerebrovascular events were also recorded.
Results
The median time from symptom onset to CA intervention was 5 days (interquartile range 3.00–9.25 days). Twenty-one patients (22.3%) underwent CA intervention within 48 hours after being admitted. Overall, 15 recurrent cerebrovascular events were observed in 12 patients (12.8%) in the period between admission and CA intervention: 3 strokes (2 strokes in progress and 1 stroke) (3.2%), 5 TIAs (5.3%), and 1 AF (1.1%) occurred within the first 72 hours (total 9.6%) of admission; 1 TIA (1.1%) occurred between 72 hours and 7 days, and 5 TIAs (5.3%) occurred after more than 7 days. The corresponding actuarial cerebrovascular recurrence rates were 11.4% (within 72 hours of admission), 2.4% (between 72 hours and 7 days), and 7.9% (after 7 days). Among baseline characteristics, no predictive factors for cerebrovascular recurrence were identified.
Procedure-related cerebrovascular events occurred at a rate of 4.3% (3 strokes and 1 TIA), and procedures performed within the first 48 hours and procedures performed after 48 hours had a similar frequency of these events (4.5% vs 4.1%, respectively; p = 0.896).
Conclusions
The in-hospital recurrence of cerebrovascular events was quite low, but all recurrent strokes occurred within 72 hours. The risk of stroke associated with a CA intervention performed within the first 48 hours was not increased compared with that for later interventions. This raises the question of the optimal timing of CA intervention in symptomatic CA stenosis. To answer this question, more data are needed, preferably from large randomized trials.

Abstract
BACKGROUND AND PURPOSE Stent retrievers have become an important tool for the treatment of acute ischemic stroke. The aim of this study was to analyze outcome and complications in a large cohort of patients with stroke treated with the Solitaire stent retriever. The study also included patients who did not meet standard inclusion criteria for endovascular treatment: low or high baseline National Institutes of Health Stroke Scale score, ≥80 years of age, extensive ischemic signs in middle cerebral artery territory, and time from symptom onset to endovascular intervention>8 hours. METHODS Consecutive patients with acute anterior circulation stroke treated with the Solitaire FR were analyzed. Data on characteristics of endovascular interventions, complications, and clinical outcome were collected prospectively. Patients who met standard inclusion criteria were compared with those who did not. RESULTS A total of 227 patients were included. Mean age was 68.2±14.7 years, and median National Institutes of Health Stroke Scale score on admission was 16 (range, 2-36). Reperfusion was successful (thrombolysis in cerebral infarction, 2b-3) in 70.9%. Outcome was favorable (modified Rankin Scale, 0-2) in 57.7% of patients who met standard inclusion criteria and 30.3% of those who did not. The rates for symptomatic intracranial hemorrhage were 3.7% and 13.1%, for death 11.4% and 33.8%, and for symptomatic intraprocedural complications 2.5% and 4.8%, respectively. CONCLUSIONS Patients<80 years of age, without extensive pretreatment ischemic signs, and baseline National Institutes of Health Stroke Scale score≤30 had high rates of favorable outcome and low periprocedural complication rates after Solitaire thrombectomy. Successful reperfusion was also common in patients not fulfilling standard inclusion criteria, but worse clinical outcomes warrant further research with a special focus on optimal patient selection.

Abstract
BACKGROUND AND PURPOSE There is some controversy on the association of the National Institutes of Health Stroke Scale (NIHSS) score to predict arterial occlusion on MR arteriography and CT arteriography in acute stroke. METHODS We analyzed NIHSS scores and arteriographic findings in 2152 patients (35.4% women, mean age 66 ± 14 years) with acute anterior or posterior circulation strokes. RESULTS The study included 1603 patients examined with MR arteriography and 549 with CT arteriography. Of those, 1043 patients (48.5%; median NIHSS score 5, median time to clinical assessment 179 minutes) showed an occlusion, 887 in the anterior (median NIHSS score 7/0-31), and 156 in the posterior circulation (median NIHSS score 3/0-32). Eight hundred sixty visualized occlusions (82.5%) were located centrally (ie, in the basilar, intracranial vertebral, internal carotid artery, or M1/M2 segment of the middle cerebral artery). NIHSS scores turned out to be predictive for any vessel occlusions in the anterior circulation. Best cut-off values within 3 hours after symptom onset were NIHSS scores ≥ 9 (positive predictive value 86.4%) and NIHSS scores ≥ 7 within >3 to 6 hours (positive predictive value 84.4%). Patients with central occlusions presenting within 3 hours had NIHSS scores <4 in only 5%. In the posterior circulation and in patients presenting after 6 hours, the predictive value of the NIHSS score for vessel occlusion was poor. CONCLUSIONS There is a significant association of NIHSS scores and vessel occlusions in patients with anterior circulation strokes. This association is best within the first hours after symptom onset. Thereafter and in the posterior circulation the association is poor.

Abstract
Background
The “RoPE Score” is a predictive model created to stratify patients by the likelihood that a patent foramen ovale (PFO) is incidental or pathogenic using clinical variables. We hypothesized that the predictors of recurrent stroke differ between patients with pathogenic and incidental PFOs.
Methods
Patients in the Risk of Paradoxical Embolism (RoPE) database with cryptogenic stroke (CS) and PFO were classified as having a probable pathogenic PFO (RoPE Score of >6, estimated PFO attributable fraction 72-99%, n=646) and others (RoPE Score of <6 points estimated PFO attributable fraction 0-72%, n=678). We tested 15 clinical, 5 radiological, and 3 echo variables for associations with stroke recurrence using Cox survival models with component database as a stratification factor. An interaction with RoPE score was checked for the variables that were significant.
Results
Follow-up was available for 91%, 80%, and 58% at 1, 2, and 3 years. Overall, a higher recurrence risk was associated with an index TIA, not being on a statin at baseline, and having a prior radiological stroke. For the low RoPE score group, older age, male sex, high cholesterol and antiplatelet (vs warfarin) treatment predicted recurrence. For those with high RoPE scores, predictors were prior (clinical) stroke/TIA and 2 echo features: septal hypermobility and a small shunt (<10 bubbles).
Conclusions
Predictors of recurrence differ when PFO relatedness is classified by the RoPE Score. The hypothesis that patients with CS and PFO form a heterogenous group with different stroke mechanisms is supported. Conventional stroke risk factors were strong predictors among patients with lower RoPE scores. Echocardiographic features - including a counterintuitive association between smaller shunts and increased recurrence risk - were uniquely predictive in the high RoPE score group (likely pathogenic PFO).

Abstract
Background
Stroke databanks have consistently found a high ratio of anterior circulation (AC) to posterior circulation (PC) strokes without significant differences when compared for vascular risk factors, stroke etiology, treatments and outcome. One study suggested that there was a deviation from this consistent observation when comparing men and women with cryptogenic stroke (CS) and patent foramen ovale (PFO). We tested these associations using the RoPE database.
Methods
The Risk of Paradoxical Embolism (RoPE) Study is an international collaboration of 12 merged cohort studies of patients with CS and known PFO status (n=3674). This analysis was restricted to those subjects in the RoPE database with index strokes in the AC or PC (excluding both or unknown) from the 7 databases that had data for CS with, and without, PFO. We compared the effect of sex on infarct location among patients with versus without PFO. We used generalized linear mixed models to examine whether PFO status modified the gender effect on infarct location adjusting for study cohort as a random effect.
Results
Among cryptogenic stroke patients both with and without PFO, AC strokes were more common (61%) than PC overall (n=1535). Among patients with PFO, PC stroke was higher in men than in women (50% vs. 33%, OR 2.23, 95% CI: 1.58-3.13). This gender effect was attenuated in those without PFO (38% vs. 31%; OR 1.32, 95% CI: 0.98-1.77). The gender-by-PFO-status interaction was significant (p= 0.0224) and was highly consistent across study cohorts.
Conclusions
These data confirm that males with CS and PFO contravene the otherwise consistent pattern that AC strokes are more commonly observed than PC strokes in stroke populations. The potential mechanisms underlying this interaction between gender and PFO-status remain to be elucidated.

Abstract
BACKGROUND AND PURPOSE Patent foramen ovale (PFO) and cryptogenic stroke are commonly associated but some PFOs are incidental. Specific radiological findings associated with PFO may be more likely to indicate a PFO-related cause. We examined whether specific radiological findings are associated with PFO among subjects with cryptogenic stroke and known PFO status. METHODS We analyzed the Risk of Paradoxical Embolism(RoPE) Study database of subjects with cryptogenic stroke and known PFO status, for associations between PFO and: (1) index stroke seen on imaging, (2) index stroke size, (3) index stroke location, (4) multiple index strokes, and (5) prior stroke on baseline imaging. We also compared imaging with purported high-risk echocardiographic features. RESULTS Subjects (N=2680) were significantly more likely to have a PFO if their index stroke was large (odds ratio [OR], 1.36; P=0.0025), seen on index imaging (OR, 1.53; P=0.003), and superficially located (OR, 1.54; P<0.0001). A prior stroke on baseline imaging was associated with not having a PFO (OR, 0.66; P<0.0001). Finding multiple index strokes was unrelated to PFO status (OR, 1.21; P=0.161). No echocardiographic variables were related to PFO status. CONCLUSIONS This is the largest study to report the radiological characteristics of patients with cryptogenic stroke and known PFO status. Strokes that were large, radiologically apparent, superficially located, or unassociated with prior radiological infarcts were more likely to be PFO-associated than were unapparent, smaller, or deep strokes, and those accompanied by chronic infarcts. There was no association between PFO and multiple acute strokes nor between specific echocardiographic PFO features with neuroimaging findings.

Abstract
BACKGROUND The optimal treatment of asymptomatic carotid stenosis (ACS) is controversial. To optimize the risk-benefit ratio of carotid artery revascularization, it is crucial to identify ACS patients who are at increased stroke risk. Recent data suggest that plaque vulnerability depends on its composition. Therefore, we assessed plaque composition in ACS to determine predictors for ipsilateral cerebrovascular events. METHODS 62 patients with 65 ACS ≥50% underwent 3-T MRI of the carotid bifurcation (TOF, special dark-blood weighted noncontrast and contrast-enhanced T(1) and T(2) images) and of the brain. The different plaque components (lipid core, intraplaque hemorrhage, calcification and the status of the fibrous cap) were assessed. Furthermore, the plaque volume and the volume of clinically silent cortical and subcortical infarcts in the territory of the stenosed carotid artery as seen on FLAIR images were determined by using a semi-automated software. Carotid stenosis was considered asymptomatic if there had not been any clinically apparent ischemic events in the corresponding vascular territory within the previous 6 months. During follow-up, information on the occurrence of cerebrovascular events, medical treatment and sonographic changes of the stenosis was collected. RESULTS At baseline, 24 ACS (37%) were classified as high grade. A lipid-rich necrotic core was the dominant plaque component in 16 ACS (25%). The plaque volume was higher in ACS with a lipid-rich necrotic core as dominant plaque component (p = 0.002) and in patients with prior stroke/TIA (p = 0.010). After a median follow-up of 18.9 months (interquartile range 3.5-30.1) there were 2 ipsilateral strokes and 3 ipsilateral TIAs. The average annual event rate was 7.7%. A lipid-rich necrotic core (HR 7.21; 95% CI 1.12-46.28; p = 0.037), sonographic progression of the stenosis (HR 7.00; 95% CI 1.13-41.34; p = 0.036), history of stroke (HR 11.03; 95% CI 1.23-99.36; p = 0.032), and the volume of clinically asymptomatic ischemic brain lesions (HR 1.14/cm(3); 95% CI 1.03-1.25; p = 0.008) predicted cerebrovascular events. Patients on statin therapy at follow-up were at lower risk of events (HR 0.17; 95% CI 0.03-1.00; p = 0.05). CONCLUSIONS In addition to medical history and sonographic findings, a lipid-rich necrotic core within the plaque turned out as a predictor of cerebrovascular events. Therefore, MR imaging of carotid plaques deserves further attention and might be helpful to improve risk stratification of asymptomatic carotid disease. The identified predictors could be combined in a risk model and tested in larger prospective studies.
