Abstract
INTRODUCTION Emergent stenting of the extracranial internal carotid artery (ICA) in stroke patients requires antiplatelet therapy to prevent in-stent thrombosis with a higher risk of intracranial haemorrhage. AIM OF THE STUDY Assess the efficacy and safety of emergent carotid stenting with intravenous tirofiban in acute ischemic stroke patients. METHODS Primary endpoint: symptomatic hemorrhage. Secondary endpoints: 90-day functional outcome and mortality. RESULTS Of the 62 patients, 21 (34%) received tirofiban as a single antiplatelet, and 41 (66%) received combined therapy. Premedication with anticoagulants and antiplatelets was significantly more frequent in the tirofiban-only group. The rate of symptomatic haemorrhage was significantly lower in the tirofiban-only group than in the combined group (4.8% vs. 27%, p = 0.046). The patients with tirofiban alone had a significantly better functional outcome at day 90 than the combined group (52% vs. 24%, p = 0.028). Mortality was equal (24%) in both groups. Pre-interventional NIHSS score (p = 0.003), significant blood pressure fluctuations (p = 0.012), tandem occlusion (p = 0.023), and thrombolysis (p = 0.044) showed relevant influence on the rate of symptomatic hemorrhage in the entire patient cohort. CONCLUSIONS A single antiplatelet therapy with tirofiban regardless of the premedication may improve the functional outcome in patients with stroke due to acute extracranial carotid lesion and emergent carotid stenting with lower rates of serious intracranial haemorrhage. For patients with high pre-interventional NIHSS score, tandem occlusion and after pre-interventional thrombolysis, caution is advised. Additionally, strict blood pressure monitoring should be conducted during the first 72 h after intervention.

Abstract
BACKGROUND Acute ischemic stroke from tandem occlusion of internal carotid artery (ICA) poses a technical challenge to neurointerventionalists. OBJECTIVE To present a novel balloon-assisted catheterization of occluded carotid artery (BOCA) technique used for rapid and effective catheterization of occluded/critically stenosed ICA in tandem occlusion. METHODS A retrospective review of 10 patients with tandem carotid occlusion, treated with BOCA technique for revascularization between July 2020 and June 2021, was performed. Clinical, radiographic, and procedural data; details of BOCA technique; complications; and outcomes were reviewed. RESULTS Of the 10 patients, 8 (80%) had complete occlusion of the cervical ICA and the remaining 2 had high-grade stenosis with poor intracranial flow. The mean age was 63.2 years. The mean presenting NIH Stroke Scale was 13.4. The BOCA technique resulted in recanalization of ICA in all patients and allowed mechanical thrombectomy of middle cerebral artery. Thrombolysis in cerebral infarction grade 2b/3 was achieved in all 10 patients. The mean groin-to-reperfusion time was 41.4 minutes. The mean internal carotid artery stenosis was 99.7% preoperatively and 41.1% postoperatively. Only one patient needed stent at the end of the procedure because of dissection. CONCLUSION The BOCA technique can be used in distal first approach for acute stroke from tandem ICA occlusion. This technique allows direct guide catheterization of occluded ICA by tracking over a partially inflated balloon.

Abstract
Background Hemorrhagic transformation (HT) following reperfusion therapies for acute ischaemic stroke often predicts a poor prognosis. This systematic review and meta-analysis aims to identify risk factors for HT, and how these vary with hyperacute treatment [intravenous thrombolysis (IVT) and endovascular thrombectomy (EVT)]. Methods Electronic databases PubMed and EMBASE were used to search relevant studies. Pooled odds ratio (OR) with 95% confidence interval (CI) were estimated. Results A total of 120 studies were included. Atrial fibrillation and NIHSS score were common predictors for any intracerebral hemorrhage (ICH) after reperfusion therapies (both IVT and EVT), while a hyperdense artery sign (OR = 2.605, 95% CI 1.212-5.599, I 2 = 0.0%) and number of thrombectomy passes (OR = 1.151, 95% CI 1.041-1.272, I 2 = 54.3%) were predictors of any ICH after IVT and EVT, respectively. Common predictors for symptomatic ICH (sICH) after reperfusion therapies were age and serum glucose level. Atrial fibrillation (OR = 3.867, 95% CI 1.970-7.591, I 2 = 29.1%), NIHSS score (OR = 1.082, 95% CI 1.060-1.105, I 2 = 54.5%) and onset-to-treatment time (OR = 1.003, 95% CI 1.001-1.005, I 2 = 0.0%) were predictors of sICH after IVT. Alberta Stroke Program Early CT score (ASPECTS) (OR = 0.686, 95% CI 0.565-0.833, I 2 =77.6%) and number of thrombectomy passes (OR = 1.374, 95% CI 1.012-1.866, I 2 = 86.4%) were predictors of sICH after EVT. Conclusion Several predictors of ICH were identified, which varied by treatment type. Studies based on larger and multi-center data sets should be prioritized to confirm the results.

Abstract
INTRODUCTION This meta-analysis assessed the predictors of symptomatic intracranial hemorrhage (sICH) after endovascular thrombectomy (EVT) for patients with acute ischemic stroke. METHODS PubMed, Embase, the Cochrane Central Register of Controlled Trials, and Web of Science were searched for studies published from inception to February 16, 2021. We included studies that evaluated the predictors of sICH after EVT. The random-effect model or fixed-effect model was used to pool the estimates according to the heterogeneity. RESULTS A total of 25 cohort studies, involving 15,324 patients, were included in this meta-analysis. The total incidence of sICH was 6.72 percent. Age (MD = 2.57, 95% CI: 1.53-3.61; p < 0.00001), higher initial NIHSS score (MD = 1.71, 95% CI: 1.35-2.08, p < 0.00001), higher initial systolic blood pressure (MD = 7.40, 95% CI: 5.11-9.69, p < 0.00001), diabetes mellitus (OR = 1.36, 95% CI: 1.10-1.69, p = 0.005), poor collaterals (OR = 3.26, 95% CI: 2.35-4.51; p < 0.0001), internal carotid artery occlusion (OR = 1.55, 95% CI: 1.26-1.90; p < 0.0001), longer procedure time (MD = 18.92, 95% CI: 11.49-26.35; p < 0.0001), and passes of retriever >3 (OR = 3.39, 95% CI: 2.45-4.71; p < 0.0001) were predictors of sICH, while modified thrombolysis in cerebral infarction score ≥2b (OR = 0.61, 95% CI: 0.46-0.79; p = 0.0002) was associated with a decreased risk of sICH. There were no significant differences in the female gender, initial serum glucose, initial ASPECT score, atrial fibrillation, oral anticoagulants, antiplatelet therapy, intravenous thrombolysis, general anesthesia, neutrophil-to-lymphocyte ratio, and emergent stenting. CONCLUSIONS This study identified many predictors of sICH. Some of the results lack robust evidence given the limitations of the study. Therefore, larger cohort studies are needed to confirm these predictors.

Abstract
Background: Intracranial hemorrhage after revascularization for acute ischemic stroke is associated with poor outcomes. Few reports have examined the relationship between parenchymal hematoma after revascularization and clinical outcomes. This retrospective study aimed to investigate the risk factors and clinical outcomes of parenchymal hematoma after revascularization for acute ischemic stroke. Methods: Ninety-three patients underwent revascularization for anterior circulation acute ischemic stroke. Patient characteristics and clinical outcomes were compared between patients with and without post procedural parenchymal hematoma using the following parameters: age, sex, occlusion location, presence of atrial fibrillation, diffusion-weighted imaging-Alberta stroke program early computed tomography score (DWI-ASPECTS), National Institute of Health Stroke Scale (NIHSS) score, recombinant tissue plasminogen activator, thrombolysis in cerebral infarction > 2b, door-to-puncture time, onset-to-recanalization time, number of passes, and modified Rankin Scale scores. Results: Parenchymal hematomas were not significantly correlated with age, sex, occlusion location, atrial fibrillation, DWI-ASPECTS, NIHSS score, recombinant tissue plasminogen activator, thrombolysis in cerebral infarction > 2b, door-to-puncture time, onset-to-recanalization time, and number of passes, but were significantly correlated with poor clinical outcomes (P = 0.001) and absence of the anterior communicating artery evaluated using pre procedural time-of-flight magnetic resonance angiography (P = 0.03). Conclusion: Parenchymal hematoma was a predictor of poor outcomes. In particular, the absence of the anterior communicating artery on pre procedural time-of-flight magnetic resonance angiography is a potential risk factor for parenchymal hematoma after revascularization for anterior circulation acute ischemic stroke.

Treatment Approaches and Outcomes for Acute Anterior Circulation Stroke Patients with Tandem Lesions. J Stroke Cerebrovasc Dis 2020; 30:105478. [PMID: 33248344 DOI: 10.1016/j.jstrokecerebrovasdis.2020.105478] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Revised: 11/11/2020] [Accepted: 11/13/2020] [Indexed: 12/12/2022] Open
Abstract
OBJECTIVES Endovascular thrombectomy (EVT) has revolutionized stroke care for large vessel occlusions (LVOs). However, over half treated remain functionally disabled or die. Patients with tandem lesions, or severe stenosis/occlusion of the cervical internal carotid artery (ICA) with intracranial LVO, may have technical EVT challenges and worse outcomes. We sought to compare treatments and outcomes for patients with anterior circulation tandem lesions versus isolated LVOs. MATERIALS AND METHODS Consecutive tandem lesion and isolated intracranial LVO patients were identified at a single center. Demographics, medical history, presentations, treatments, and outcomes were collected and analyzed. RESULTS From 381 EVT patients, 62 had tandem lesions related to atherosclerosis (74%) or dissection (26%). Compared to isolated intracranial LVOs, they were younger (63 vs 70, p = 0.003), had less atrial fibrillation (13% vs 40%, p < 0.0001), less adequate reperfusion (TICI 2b-3, 58% vs 82%, p < 0.0001), more intracranial hemorrhage (ICH, 13% vs 5%, p = 0.037), but similar 90-day functional independence (mRS 0-2, 34% vs 43%, p = 0.181). The cervical ICA was treated before intracranial EVT (57%), after (13%), not acutely (22%), or was inaccessible (8%). Acute cervical ICA treatments were stenting (57%) or angioplasty alone (13%). Neither acute stenting nor order of treatment was associated with outcomes (TICI 2b-3, ICH, or 90-day mRS 0-2). Among acutely stented, neither alteplase nor antiplatelets were associated with outcomes or stent patency. CONCLUSIONS Tandem lesions were associated with less reperfusion, more ICH, but similar 90-day functional independence. No treatment approach was associated with outcomes. These data illustrate the technical challenges of tandem lesion treatment and underscore the importance of developing new approaches.

Carotid stent occlusion after emergent stenting in acute ischemic stroke: Incidence, predictors and clinical relevance. Atherosclerosis 2020; 313:8-13.

Abstract
BACKGROUND AND AIMS Emergent stent placement may be required during neurothrombectomy. Our aim was to investigate the incidence, predictors and clinical relevance of early extracranial carotid stent occlusion following neurothrombectomy. METHODS We retrospectively analyzed a cohort of 761 consecutive neurothrombectomies performed at our center between May 2010 and August 2018, from whom a total of 106 patients had acute internal carotid artery occlusions. Early stent occlusion was defined as complete vessel occlusion within 24 h of neurothrombectomy. Clinical outcome was evaluated at day 90 with the modified Rankin Score scale (mRS). Pretreatment, procedural and outcome variables were recorded and analyzed using logistic regression. RESULTS Carotid stenting was performed in 99 (13%) patients. Of those, 22 (22%) had early stent occlusion at follow-up. Stent occlusion was associated with a lower use of post-stenting angioplasty [adjusted OR (aOR) = 11.2, 95%CI = 2.49-50.78, p = 0.002)], increased residual intrastent stenosis (aOR = 2.1, 95%CI = 1.38-3.06, p < 0.001) and unsuccesful intracranial recanalization (modified TICI score 0-2a) (aOR = 13.5, 95%CI = 1.97-92.24, p = 0.008). Stent occlusion was associated with poor clinical outcome at day 90 (poorer mRS shift, aOR = 3.9, 95%CI = 1.3-11.3, p = 0.014; mRS>2, aOR = 6.3, 95%CI = 1.8-22.7, p = 0.005), and with an increased rate of symptomatic intracranial hemorrhage at 24 h (14% versus 1%, p = 0.033). CONCLUSIONS Early carotid stent occlusion occurred in one out of five neurothrombectomies and was associated with periprocedural factors that included increased residual intrastent stenosis, a lower use of post-stenting angioplasty and unsuccessful intracranial recanalization. Further investigation is warranted for the evaluation of strategies aimed to prevent carotid stent occlusion.

Abstract
BACKGROUND AND PURPOSE Acute ischemic stroke due to tandem occlusive lesions involves high-grade ICA stenosis or occlusion with a distal intracranial occlusion. Several approaches and devices exist in the treatment of tandem occlusions; however, a consensus on the optimal technique does not exist. The Dotter technique is a method of catheter-based angioplasty to recanalize cervical ICA occlusions. We present a modified dilator-Dotter technique, which involves a polyethylene, tapered inner dilator to initially cross the occlusion, followed by guide catheterization and subsequent intracranial thrombectomy. The purpose of this study was to examine the safety and efficacy of this dilator-Dotter technique. MATERIALS AND METHODS We performed a retrospective review of patients with acute stroke due to tandem ICA intracranial occlusions, treated with our dilator-Dotter technique and thrombectomy between June 2018 and December 2019. We examined clinical, radiographic, and procedural data, as well as complications and outcomes. RESULTS Thirty-two patients were included. In 100% of cases, the dilator-Dotter technique resulted in ICA recanalization allowing successful thrombectomy. TICI 2b-3 revascularization was obtained in 31 patients (96%), within an average time of 25 minutes. The average preprocedural ICA stenosis was 98%, including 23 patients (72%) with complete occlusion. Following the dilator-Dotter technique, average ICA stenosis improved to 59%. There were no instances of death, iatrogenic dissection, emboli to new territory, or symptomatic intracranial hemorrhage. CONCLUSIONS The dilator-Dotter technique may be a safe and effective modification of the traditional Dotter technique in allowing rapid ICA recanalization in cases of acute ischemic stroke due to tandem occlusions.

Abstract
Introduction Acute ischemic strokes with tandem occlusions, which represent 10–20% of all ischemic strokes, have a particularly poor prognosis. Since emergent treatment of tandem lesions has not been specifically addressed in randomized trials, there is an absence of standardized management. Objective We sought to assess the efficacy and safety of acute endovascular treatment in stroke due to tandem occlusions in our center and compare the results with previous reports. Methods From a prospective registry we analyzed data of 99 consecutive patients (males: 77.7%, mean age ± SD: 67.5 ± 9.5 years) with stroke due to tandem occlusions who underwent treatment with emergent carotid stenting and intracranial mechanical thrombectomy. Successful recanalization was defined as a TICI score of 2b-3 and a good functional outcome was defined as a modified Rankin scale score ≤2 at 90 days. Symptomatic intracranial hemorrhage (sICH) was considered when associated with worsening on the National Institutes of Health Stroke Scale (≥4 points). Results A successful recanalization rate was achieved in 87.8 and 48.5% of the patients had a good functional outcome. sICH and mortality rates were 12.1 and 20.2%, respectively, and 21.2% of the patients received combined treatment with intravenous thrombolysis, which did not affect neither the prognosis nor the recanalization or sICH rates. The time from symptom onset to recanalization and the degree of recanalization were the main factors associated with prognosis and the occurrence of sICH. Conclusions Our results suggest that endovascular treatment with emergent carotid stenting and intracranial thrombectomy in patients with acute stroke due to tandem occlusions is an effective and safe procedure.

Abstract
Objective Although stroke guidelines recommend antiplatelets be started 24 hours after tissue plasminogen activator (tPA), select mechanical thrombectomy (MT) patients with luminal irregularities or underlying intracranial atherosclerotic disease may benefit from earlier antiplatelet administration. Methods We explore the safety of early (<24 hours) post-tPA antiplatelet use by retrospectively reviewing patients who underwent MT and stent placement for acute ischemic stroke from June 2015 to April 2018 at our institution. Results Six patients met inclusion criteria. Median presenting and pre-operative National Institutes of Health Stroke Scale scores were 14 (Interquartile Range [IQR] 5.5–17.3) and 16 (IQR 13.7–18.7), respectively. Five patients received standard intravenous (IV) tPA and one patient received intra-arterial tPA. Median time from symptom onset to IV tPA was 120 min (IQR 78–204 min). Median time between tPA and antiplatelet administration was 4.9 hours (IQR 3.0–6.7 hours). Clots were successfully removed from the internal carotid artery (ICA) or middle cerebral artery (MCA) in 5 patients, the anterior cerebral artery (ACA) in one patient, and the vertebrobasilar junction in one patient. All patients underwent MT before stenting and achieved thrombolysis in cerebral infarction 2B recanalization. Stents were placed in the ICA (n=4), common carotid artery (n=1), and basilar artery (n=1). The median time from stroke onset to endovascular access was 185 min (IQR 136–417 min). No patients experienced symptomatic post-procedure intracranial hemorrhage (ICH). Median modified Rankin Scale score on discharge was 3.5. Conclusions Antiplatelets within 24 hours of tPA did not result in symptomatic ICH in this series. The safety and efficacy of early antiplatelet administration after tPA in select patients following mechanical thrombectomy warrants further study.

Abstract
BACKGROUND AND PURPOSE The number of acute and early stent occlusions after emergency stenting of the internal carotid artery (ICA) in patients with tandem lesions is unclear and only mentioned in a small number of publications, ranging from 0-20%. A recent article by Yilmaz et al. reported a high rate of acute in-stent occlusions of 45% within 72 h after deployment of CASPER dual layer stents. METHODS All patients with acute ischemic stroke treated with a CASPER stent between August 2014 and April 2018 were retrospectively evaluated for occlusion rates, periinterventional medication and early complications. A total of 66 patients, 45 with tandem pathologies and 21 with proximal ICA stenosis only were enrolled. RESULTS Thrombotic complications occurred in 16 out of 66 patients (24%) and hemorrhagic complications in 8/66 (12%) and 15 of the 16 thrombotic complications and 7/8 symptomatic intracranial hemorrhages (sICH) occurred in patients with tandem lesions and accessory intracranial thrombectomy. Of the patients with sICH five were treated in a prolonged or unknown time window. In patients with intraprocedural thrombotic complications ultrasound imaging showed patent stents in 13 of the 14 patients CONCLUSIONS: The CASPER stent system showed a high technical success rate in patients with acute stroke. The number of patients with sICH was not higher than the numbers reported in the published literature despite the early use of Gp IIb/IIIA inhibitors, whereas the number of thrombotic complications was smaller than that reported in recent studies. The majority of sICH occurred in patients treated because of tandem lesions in an unknown or prolonged time window.

Abstract
BACKGROUND AND PURPOSE Acute tandem occlusions often require carotid stenting. Combination of mechanical and pharmacologic therapies in addition to antiplatelet drugs administered to prevent acute stent thrombosis might increase the risk of intracerebral hemorrhage. We present a protocol of antiplatelet regimen based on early post-procedural dual-energy CT (DE-CT). MATERIAL AND METHODS Fifty consecutive stroke patients with tandem occlusions treated with acute carotid stenting after intracranial thrombectomy and TICI 2b/3 were reviewed. All patients received intravenous lysine acetylsalicylate during the procedure. Dual (aspirin+clopidogrel with or without clopidogrel load, groups A and B, respectively) or mono (aspirin) antiplatelet regimen (group C) was administered 12-24 h later according to brain DE-CT findings. Carotid ultrasonography was performed at 24 h and before discharge. We evaluated the rate of subsequent symptomatic intracranial hemorrhage (SICH) and acute stent thrombosis in each group. RESULTS Between June 2014 and December 2016, 50 patients were included (mean age 66 years, 76% men, baseline NIHSS 16, median time from symptom onset to recanalization 266 min). According to DE-CT, 24 patients were assigned to group A, 19 to group B and 7 to group C (4 of them had SICH at that time). One patient suffered a subsequent SICH (belonging to group B). There was only one stent thrombosis without clinical repercussions in group B. CONCLUSIONS DE-CT may contribute to select antiplatelet regimen after acute carotid stenting in tandem occlusions.

Abstract
Purpose Emergent intracranial occlusions causing acute ischemic stroke are often related to extracranial atherosclerotic stenosis. This study aimed to investigate the association between post-procedure intracerebral hemorrhage (ICH) and emergent extracranial artery stenting and assess their effects on clinical outcomes in patients with acute ischemic stroke. Materials and Methods We retrospectively analyzed patients undergoing hyperacute endovascular treatment for cervicocephalic vascular occlusion in three Korean hospitals between January 2011 and February 2016. Patients who had extracranial artery involvement and were treated from 24 hours of symptom onset to puncture were included in this study, and they were divided into the extracranial stenting (ES) and non-ES groups. Any type of petechial hemorrhages and parenchymal hematoma was defined as ICH for the current study. Results In total, 76 patients were included in this study. Among them, 56 patients underwent ES, and 20 patients did not. Baseline characteristics, risk factors, laboratory data, treatment methods, successful reperfusion rates, and baseline stenotic degrees of extracranial internal carotid artery did not differ between these two groups. However, atrial fibrillation was more frequent in patients without than with ES (P=0.002), and post-procedure ICH was more frequent in patients with than without ES (P=0.035). Logistic regression models revealed that ES was independently associated with post-procedure ICH (odds ratio [OR], 7.807; 95% confidence interval [CI], 1.213–50.248; P=0.031), and ICH was independently associated with poor clinical outcomes (OR, 0.202; 95% CI, 0.054–0.759; P=0.018); however, ES itself was not associated with clinical outcomes (OR, 0.530; 95% CI, 0.117–2.395; P=0.409). Notably, ICH and ES had interaction for predicting good outcomes (P=0.041). Conclusion Post-procedure ICH was associated with ES and poor clinical outcomes. Therefore, ES should be cautiously considered in patients with hyperacute stroke.

Abstract
Background Acute ischemic stroke due to tandem occlusive lesions of the anterior circulation involves an intracranial large vessel occlusion as well as a concurrent occlusion or high-grade stenosis of the proximal carotid system. The vast majority of proximal lesions in tandem occlusive cases involve the extracranial internal carotid artery, although the lesion can theoretically exist anywhere along the carotid artery pathway, including the common carotid ostium. Summary To the best of our knowledge, only 1 report describes common carotid artery ostial lesions in the setting of acute ischemic stroke due to tandem occlusions, in which the authors describe an anterograde treatment paradigm. We present the first 2 cases of acute ischemic stroke secondary to common carotid ostial disease with tandem intracranial occlusion, treated with intracranial thrombectomy followed by subsequent staged balloon-mounted stenting of the common carotid ostium. We review the pathophysiology of tandem occlusions, the controversy surrounding treatment techniques, and various approaches used in the treatment of ostial occlusive lesions. Key Message In certain situations where acute carotid stenting is not safe or technically possible, immediate intracranial thrombectomy with a subsequent staged balloon-mounted stenting of the ostial lesion may be a reasonable and safe option.

Abstract
BACKGROUND Carotid artery stenting requires antiplatelet therapy for prevention of in-stent thrombosis. Patients suffering from acute ischemic stroke undergoing intravenous thrombolysis and emergent carotid artery stenting (eCAS) are at high risk for intracranial bleeding. We assessed efficacy and safety of acute administration of intravenous tirofiban versus aspirin in these patients. METHODS A retrospective, single center, cohort study was carried out of 32 patients who underwent eCAS (18 received tirofiban, 14 received aspirin) at our comprehensive stroke center (2008-2016). RESULTS Of our 32 consecutive eCAS patients, favorable clinical outcomes (modified Rankin scale ≤ 2) were achieved in eight (47%) tirofiban patients and six (46%) aspirin patients ( p = 0.96). Overall rates were similar for symptomatic intracranial bleeding (tirofiban 22%, aspirin 29%, p = 0.68) and mortality (tirofiban 18%, aspirin 23%, p = 0.71). CONCLUSIONS Tirofiban and aspirin demonstrated similar efficacy and safety in thrombolyzed stroke patients who underwent eCAS in our cohort. Intravenous tirofiban with its short half-life might represent an alternative to aspirin in select patients.

Abstract
Objective To compare outcomes following intracranial stent retriever-based intracranial thrombectomy (SRT) with emergency extracranial internal carotid artery (EICA) stenting or angioplasty alone in patients presenting with acute stroke due to tandem occlusions of the ICA. Methods Consecutive patients with acute anterior tandem occlusion who received an endovascular intervention within 6h of symptom onset between January 2013 and June 2016 were included in this prospective study. Demographic, radiological, procedural and clinical outcome data were compared between the stenting and the angioplasty alone groups. Results Of the 37 patients eligible for the study, 18 had angioplasty alone and 19 underwent stent placement. Successful recanalization rate was statistically significantly higher in the stenting group than in angioplasty alone group (74% vs. 39%) and although not statistically significant, more patients in the stenting group than in the angioplasty alone group had favourable outcomes (63% vs. 50%). There was no significant difference between groups in rates of symptomatic intracranial haemorrhage (SICH), cerebral herniation or mortality. Conclusion This study in a small sample size suggests that among patients with acute anterior tandem occlusion, SRT with EICA stenting tended to achieve higher recanalization and improved clinical outcomes at three months compared with SRT and angioplasty alone with a similar rate of SICH and mortality.

Abstract
INTRODUCTION Endovascular intracranial thrombectomy (IT) has established itself as the standard of care in treating large-vessel anterior circulation acute ischemic stroke (AIS). However, internal carotid artery (ICA) stenosis/occlusion hampers distal access and controversy about simultaneous emergency ICA stenting ensues. The purpose of this review was to evaluate the safety of emergency ICA stenting in combination with IT for AIS with tandem occlusions. To our knowledge this is the first meta-analysis to evaluate emergency ICA stenting in tandem occlusions, combining results from studies with a control group. EVIDENCE ACQUISITION A meta-analysis was conducted according to the recommendations of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. EVIDENCE SYNTHESIS A total of 649 potentially relevant articles were initially selected. After reviewing at title or abstract level, 87 articles were read in full and 23 were included. These studies recruited 1000 patients, 220 submitted to IT with no emergency ICA stenting and 780 to IT and emergency ICA stenting. Successful revascularization (Thrombolysis in cerebral infarction scale [TICI] ≥2b) was achieved in 48.6-100%. Good outcome (modified Rankin scale [mRS] ≤2) ranged from 18.2-100%. Symptomatic intracranial hemorrhage (sICH) ranged from 0-45.7% (overall N.=168; 17.2%). Mortality at 90 days ranged from 0-45.4% (overall N.=114; 11.7%). Time to recanalization was significantly longer in the stenting group with an overall mean difference of 1.76 (95% CI: 1.59-1.93). CONCLUSIONS In this meta-analysis time to recanalization was significantly longer in the emergency ICA stenting group. There was no benefit from emergency stenting in parameters such as successful revascularization (TICI≥2b), clinical outcome (mRS≤2) or 90-day mortality. Data on sICH were scarce. Emergency ICA stenting appears to increase time to revascularization and increase the risk of complications with no demonstrated clinical benefit. Furthermore, no prospective, randomized controlled trials demonstrating relative efficacy and safety of concomitant ICA stenting have been published to date. Additional studies must be undertaken to define the role of angioplasty and stenting of the extracranial carotid arteries in the early management of acute stroke in tandem occlusions. Until then, we recommend that ICA stenting concomitant to thrombectomy in acute stroke patients should be avoided.

Endovascular management of extracranial occlusions at the hyperacute phase of stroke with tandem occlusions. J Neuroradiol 2017; 45:196-201. [PMID: 29132938 DOI: 10.1016/j.neurad.2017.10.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Accepted: 10/24/2017] [Indexed: 11/30/2022]
Abstract
BACKGROUND AND PURPOSE The management of cervical artery occlusions in hyperacute stroke with tandem cervical/intracranial occlusions has not yet become standardized, especially when the circle of Willis is effective. METHODS We retrospectively analyzed the safety and accuracy of current approaches to manage the cervical occlusion in consecutive patients with tandem occlusions addressed for intracranial mechanical thrombectomy (MT) in our department from January 2012 to May 2017. The different approaches that could be performed in a same patient during the same procedure or hospitalization were analyzed separately. RESULTS We reported 64 approaches to manage the cervical occlusion in 49 patients with tandem occlusion (14% of MT): medical treatment alone in 16/64 (25%), stenting/angioplasty in 16/64 (25%), occlusion with coils in 12/64 (19%), angioplasty alone in 9/64 (14%), stent-retriever in 8/64 (12%), and/or thromboaspiration in 3/64 (5%). Early ipsilateral embolic recurrence occurred after 9/64 (14%) of them. It was strongly associated with the presence of a cervical intraluminal thrombus (P=0.001) and was then lower after occlusion with coils and stent-retriever compared to medical treatment alone and thromboaspiration (P=0.002). Occlusion with coils had a lower rate of radiological intracranial hemorrhage at 48-hour compared to other approaches (P=0.009). The 3-month rates of favorable outcome (P=0.806) and mortality (P=0.878) were similar. One delayed stroke was imputable to an occlusion with coils, for a median (Q1-Q3) follow-up of 10 (3-20) months. CONCLUSIONS Cervical occlusion with coils and thrombectomy with stent-retrievers may be relevant to prevent early embolic recurrence in cervical occlusions with intraluminal thrombus. Stent-retrievers should be further assessed as a first-line approach, since delayed stroke may occur following occlusion with coils. Medical treatment alone may be sufficient when no cervical intraluminal thrombus is present, the Willis polygon is effective, and the cervical occlusion can be crossed easily to perform the intracranial thrombectomy.

Abstract
BACKGROUND A loading dose of antiplatelets reduces in-stent thrombosis after stent implantation. However, whether it is safe in patients undergoing acute stenting after intravenous recombinant tissue plasminogen activator (rt-PA) is unclear. METHODS A case series of acute ischemic stroke patients treated with intravenous rt-PA followed by emergent stenting were prospectively included in Jinling Hospital Stroke Unit. An emergent loading dose of antiplatelets (aspirin 300 mg and clopidogrel 300 mg) were administered to all patients through a nasogastric tube immediately before stenting. Clinical and angiographic outcomes were evaluated in these patients. RESULTS A total of 12 patients were included. The median of NIHSS score on admission was 15 points (interquartile range 11-19). The median of time from stroke symptom onset to start IV rt-PA and stent placement was 172 min (interquartile range 123.75-189) and 311.5 min (interquartile range 285.5-349.5), respectively. All patients reached complete or partial recanalization (TICI ≥2a). One patient occurred hemorrhagic transformation at 24 h following the emergent loading dose of antiplatelets. A favorable outcome as defined by mRS ≤2 at 90 days was obtained in 58.3% (7/12) of all patients. CONCLUSION Our finding preliminary suggested that an emergent loading dose of antiplatelets may be safe and feasible for acute stenting after IV rt-PA.

Abstract
After a period of stagnation due to negative results of randomized trials for patients with symptomatic stenosis, the relevance of carotid artery stenting (CAS) is increasing again. CAS has become an important and evidence-based part of interventional stroke treatment. Our ability to manage acute recanalization of carotid occlusions and other niche indications properly led some skeptical neurologists to trust in carotid intervention for elective cases as well. The evolution of CAS from initial euphoria to more realistic views under consideration of trial results and guidelines is reviewed. Quality assurance in Germany proves that CAS complication rates within the carotid endarterectomy (CEA) quality criteria are feasible even with higher proportions of high-risk patients. Recent trial results showed that long-term efficacy of CAS or CEA are not significantly different. Other than in symptomatic stenoses, acute complication rates of both means treatment does not differ in asymptomatic patients, where medical therapy becomes increasingly competitive. Technical issues of CAS like the cell design of stents or the usefulness of embolic protection are still under discussion. We will see whether CAS results will further improve over time. Standardized techniques, proper training, and patient selection are important for acute and elective cases.

Abstract
Background The aim of the study was to assess the efficacy of balloon angioplasty-assisted mechanical thrombectomy without urgent stenting in the carotid artery as another approach for endovascular treatment of tandem occlusions. Methods Fifteen consecutive cases of tandem occlusions treated with the endovascular approach between January 2014 and May 2016 were reviewed. The study cohort included patients with an etiology of large vessel atherosclerosis. Extracranial carotid stenting was performed in another session if post-thrombectomy mRS modified Rankin Score (mRS) was 0-2. Good clinical outcome was determined by follow-up at 7-10, 30 and 90 days according to the mRS. Results Most patients (80%) were male. Eight (53.4%) patients received intravenous thrombolysis before angiography. Proximal revascularization was successful in 100% of cases with balloon angioplasty internal carotid artery (ICA) origin. Successful recanalization (modified thrombolysis in cerebral infarction (mTICI) 2b-3) (mTICI 2 b-3) occurred in 12 cases (80%) and good clinical outcomes were achieved in 10 patients (66.7%). Cervical ICA stent placement was performed in 10 patients with good clinical outcomes. No symptomatic intracranial hemorrhage occurred after delayed ICA stenting Conclusions This is the first reported case series to evaluate this approach for endovascular treatment of tandem occlusions. Carotid angioplasty-assisted mechanical thrombectomy without urgent stenting seems to be a safer approach.

Abstract
BackgroundThe use of retrievable stents for endovascular clot retrieval has dramatically improved successful revascularization and clinical outcome in selected patients with acute stroke.ObjectiveTo describe the rate and clinical consequences of unwanted spontaneous detachment of these devices during mechanical thrombectomy.MethodsWe studied 262 consecutive patients treated with the retrievable stent, Solitaire, for acute ischemic stroke between November 2008 and April 2015. Clinical, procedural, and outcome variables were compared between patients with and without unexpected detachment of this device. Detachment was classified as proximal to the stent proximal marker (type A) or distal to the marker (type B). Poor functional outcome was defined as modified Rankin scale score >2 at 90 days.ResultsUnwanted detachment occurred in 6/262 (2.3%) cases, four of type A and two of type B. Stent recovery was possible in three patients, all of ‘type A’, but in none of ‘type B’. The number of prior passes was higher in patients with undesired detachment (3 (2–5) vs 2 (1–3), p=0.007). Detachment was associated with higher rate of symptomatic intracranial hemorrhage (SICH) (33.3% vs 4.3%, p=0.001), poorer outcome (100% vs 54.8%, p=0.028), and higher mortality rate at 90 days (50% vs 17%, p=0.038).ConclusionsUnwanted detachment of a Solitaire is an uncommon complication during mechanical thrombectomy in patients with acute ischemic stroke and is associated with the clot retrieval attempts, SICH, poor outcome, and higher mortality.

Abstract
BACKGROUND Dual antiplatelet therapy is associated with increased rates of intracerebral hemorrhage, especially in the context of subarachnoid hemorrhage. We present a case of a spontaneous hemorrhage in a patient treated with a Pipeline stent for a ruptured dissecting vertebrobasilar aneurysm and the novel use of direct application of platelets during surgery to control bleeding. CASE DESCRIPTION A 54-year-old previously healthy woman presented with an intradural right vertebral artery dissection with a ruptured 6-mm pseudoaneurysm. The patient was started on aspirin and clopidogrel and the vessel was reconstructed with 2 Pipeline Embolization Devices. On postbleed day number 14, she became obtunded with a blown right pupil; computed tomography of the head demonstrated a large right temporal intracerebral hematoma. The patient was taken emergently to the operating room for evacuation of the clot. Intraoperatively, satisfactory control of bleeding was not achieved despite transfusing several units of platelets intravenously. Ultimately, a mixture of Floseal and platelets applied directly to the hematoma wall allowed prompt hemostasis. At 3 months the patient was doing extremely well clinically and angiography demonstrated occlusion of the aneurysm. CONCLUSIONS This is the first reported description of direct application of platelets to achieve intraoperative hemostasis. Platelets are activated by thrombin and collagen and the use of Floseal (a bovine-derived, gelatin matrix and human-derived thrombin) further potentiated the effectiveness of this strategy. With the increased incidence of intracerebral hemorrhage associated with dual antiplatelet therapy, this technique may provide a useful tool in the neurosurgical armamentarium.

Abstract
Hemorrhagic transformation (HT) is a common complication of ischemic stroke that is exacerbated by thrombolytic therapy. Methods to better prevent, predict, and treat HT are needed. In this review, we summarize studies of HT in both animals and humans. We propose that early HT (<18 to 24 hours after stroke onset) relates to leukocyte-derived matrix metalloproteinase-9 (MMP-9) and brain-derived MMP-2 that damage the neurovascular unit and promote blood-brain barrier (BBB) disruption. This contrasts to delayed HT (>18 to 24 hours after stroke) that relates to ischemia activation of brain proteases (MMP-2, MMP-3, MMP-9, and endogenous tissue plasminogen activator), neuroinflammation, and factors that promote vascular remodeling (vascular endothelial growth factor and high-moblity-group-box-1). Processes that mediate BBB repair and reduce HT risk are discussed, including transforming growth factor beta signaling in monocytes, Src kinase signaling, MMP inhibitors, and inhibitors of reactive oxygen species. Finally, clinical features associated with HT in patients with stroke are reviewed, including approaches to predict HT by clinical factors, brain imaging, and blood biomarkers. Though remarkable advances in our understanding of HT have been made, additional efforts are needed to translate these discoveries to the clinic and reduce the impact of HT on patients with ischemic stroke.
