Abstract
Background Cerebral venous sinus thrombosis (CVST) is a form of the cerebrovascular disease characterized by varying degrees of obstruction of veins and cerebral sinuses caused by thrombus. Diagnosis is incredibly challenging due to the wide variety of symptoms and the distinct radiological aspects of affected vessels. In patients with venous thrombosis, the presence of D-Dimer is used as an indicator of the presence of endogenous fibrinolysis. D-Dimer is a by-product of fibrin polymer fragmentation. Objective To investigate the relationship between the level of D-Dimer and the number of sinuses in CVST by Digital Subtraction Angiography (DSA). Methods Retrospective data from September 2021 to September 2022 were used in this analytical observational with a cross-sectional study design. Chi-Square is used for data processing relationship analysis. Results Out of the 54 subjects with elevated levels of D-Dimer, 38 (70.4%) are females, whereas 16 (29.6%) are males. High levels of D-Dimer have been related to a greater risk of sinus thrombosis (p < 0.001). D-Dimer levels were similarly shown to rise in conjunction with the number of sinuses most severely damaged by thrombosis. The most common site for thrombosis to develop in this study were the left sigmoid and left transverse sinuses. Most risk factors were hormonal. Conclusion There is a statistically significant relationship between an increase in the D-Dimer level and the greater number of sinuses involved as determined by DSA in individuals diagnosed with CVST.

Abstract
OBJECTIVE To determine the epidemiology of prolonged psychogenic non-epileptic seizures (pPNES) misdiagnosed as status epilepticus, as well as the risks associated with non-indicated treatment. METHODS We performed an individual patient data analysis from the Rapid Anticonvulsant Medication Prior to Arrival Trial (RAMPART) and the Established Status Epilepticus Treatment Trial (ESETT) to assess incidence, patient characteristics and clinical course of misdiagnosed pPNES. RESULTS Among 980 patients aged 8 years or older diagnosed and treated for status epilepticus in RAMPART and ESETT, 79 (8.1%) were discharged with a final diagnosis of pPNES. The relative incidence was highest in adolescents and young adults (20.1%). The typical female preponderance seen in that age bracket was not evident in children and older adults. Adverse effects, including respiratory depression and intubation, were documented in 26% of patients with pPNES receiving benzodiazepines in RAMPART and 33% of patients receiving additional second-line medication in ESETT. In ESETT, patients who were treated with benzodiazepines before hospital admission had higher rates of unresponsiveness and severe adverse effects than those treated after admission, suggesting cumulative effects of accelerated treatment momentum. Across trials, one in five patients with pPNES were admitted to an intensive care unit. CONCLUSIONS Misdiagnosis and treatment of pPNES as status epilepticus are a common and widespread problem with deleterious consequences. Mitigating it will require training of emergency staff in semiological diagnosis. Status epilepticus response protocols should incorporate appropriate diagnostic re-evaluations at each step of treatment escalation, especially in clinical trials.

Potential value of the calibrated automated thrombogram in patients after a cerebral venous sinus thrombosis; an exploratory study. Thromb J 2021; 19:81.

Abstract
Background Cerebral venous sinus thrombosis (CVST) is a relatively rare, but potentially lethal condition. In approximately 15% of the patients, the cause of CVST remains unclear. Conventional clotting tests such as prothrombin time and activated partial thromboplastin time are not sensitive enough to detect prothrombotic conditions nor mild haemostatic abnormalities. The calibrated automated thrombogram (CAT) is a physiological function test that might be able to detect minor aberrations in haemostasis. Therefore, we aimed to detect the presence of a prothrombotic state in patients who endured idiopathic CVST with the CAT assay. Methods Five adult patients with an idiopathic, radiologically proven CVST that had been admitted during the past 3 years were included in this study. The control group consisted of five age/gender matched healthy volunteers. Exclusion criteria were known haematological disorders, malignancy (current/past) or hormonal and anticoagulant therapy recipients. We obtained venous blood samples from all participants following cessation of anticoagulation. Using the CAT assay, we determined lag time, normalized endogenous thrombin potential (ETP), ETP reduction and normalized peak height. In addition, prothrombin concentrations were determined. Results We found no significant differences in lag time (4.7 min [4.5–4.9] vs 5.3 min [3.7–5.7], p = 0.691), normalized ETP (142% [124–148] vs 124% [88–138], p = 0.222), ETP reduction (29% [26–35] vs 28% [24–58], p > 0.999), and normalized peak height (155% [153–175] vs 137 [94–154], p = 0.056) between patients and their age/gender matched controls. In addition, prothrombin concentrations did not significantly differ between patients and controls (120% [105–132] vs 127% [87–139], p > 0.999). Conclusion Reasons for absent overt hypercoagulability within this study population may be the small patient sample, long time since the event (e.g. 3 years) and avoidance of acquired risk factors like oral contraception. Given the fact that CVST is a serious condition with a more than negligible risk of venous thrombosis event recurrence, exclusion of clinically relevant hypercoagulability remains a challenging topic to further study at the acute and later time points, particularly in patients with idiopathic CVST.

Abstract
INTRODUCTION Cases of cerebral venous sinus thrombosis have been reported in individuals vaccinated against COVID-19 with non-replicating adenoviral vector vaccines. We issue our recommendations on the diagnosis and management of patients presenting this complication. METHODS The multidisciplinary working group, led by the Spanish Federation of Medical and Scientific Associations (FACME) and including representatives of several scientific societies, reviewed the available evidence from the literature and reports of the European Medicines Agency. We establish a definition for suspected cases and issue diagnostic and treatment recommendations regarding vaccine-induced immune thrombotic thrombocytopaenia. RESULTS We define suspected cases as those cases of cerebral venous sinus thrombosis occurring between 3 and 21 days after the administration of non-replicating adenoviral vector vaccines, in patients with a platelet count below 150 000/μL or presenting a decrease of 50% with respect to the previous value. Findings suggestive of vaccine-induced immune thrombotic thrombocytopaenia include the presence of antibodies to platelet factor 4, D-dimer levels 4 times greater than the upper limit of normal, and unexplained thrombosis. The recommended treatment includes intravenous administration of non-specific human immunoglobulin or alternatively plasmapheresis, avoiding the use of heparin, instead employing argatroban, bivalirudin, fondaparinux, rivaroxaban, or apixaban for anticoagulation, and avoiding platelet transfusion. CONCLUSIONS Non-replicating adenoviral vector vaccines may be associated with cerebral venous sinus thrombosis with thrombocytopaenia; it is important to treat the dysimmune phenomenon and the cerebral venous sinus thrombosis.

Abstract
Antiphospholipid syndrome (APS) with cerebral venous sinus thrombosis (CVST) is a relatively rare phenomenon, and this observational study aimed to investigate the clinical characteristics of APS patients complicated with CVST. We retrospectively investigated the clinical characteristics of CVST events in APS and compared differential characteristics and associated factors between APS patients with and without CVST. Twenty-one CVST patients with APS were enrolled including 14 females (9.4%) and 7 males (5.8%). The median age and disease duration at onset of CVST was 33 years (IQR 28-48) old and 1.3 months (IQR 0.7-4), respectively. Among APS patients with CVST, 12 (57.1%) cases presented with neurologic symptoms of CVST as the initial manifestation. Onset of CVST was mainly chronic (52.4%). Headache (90.5%) was the most common neurological symptom. The common locations of CVST were transverse sinus (76.2%) and superior sagittal sinus (57.1%), with more frequently (76.2%) dual or multiple sinuses involved. All patients with CVST were treated with anticoagulant, and 5 (23.8%) patients received endovascular therapy. Sixteen (84.2%) patients had good outcomes and 3 (15.8%) patients died at last follow-up. There were no significant differences (P > 0.05) between two groups in the analysis of related APS indicators. There were no significant differences (P > 0.05) between two groups in the analysis of related APS indicators. Although APS complicated with CVST is rare and predominately chronic developed. The evaluation of CVST should be performed for APS patients with intracranial hypertension syndrome. The routine screening of antiphospholipid antibodies (aPLs) is highly recommended in unexplained CVST patients. Most CVST patients with APS will have a good prognosis after treatment, and endovascular therapy is an alternative treatment.

Abstract
Cerebral venous sinus thrombosis (CVST) is a cause of secondary headache with substantial morbimortality. Headache dominates the clinical presentation, but no typical phenotype has been described. We aim to evaluate the presence of red flags in headache in patients with confirmed CVST at the moment of emergency department (ED) presentation.Retrospective STROBE compliant cohort study including patients with confirmed CVST that consulted because of headache at the ED. We analyzed presence and type of red flags at the moment of consult. We evaluated whether CVST was suspected at the moment of imaging request and analyzed delay in the diagnosis.Nineteen patients fulfilled inclusion and exclusion criteria. Mean age was 48.5 years, 47.4% were female. All the studied patients exhibited at least 1 red flag, being abnormal neurological examination the most frequent (79%), followed by the presence of other neurological symptoms (68%), alarm data related with headache phenotype (63%), or risk factors concerning prior medical history (47%). Temporal pattern of the headache was acute in 42.1%, thunderclap in 31.6%, and subacute in 26.3%. In none patient CVST was the specific suspicion when imaging was requested. Median time since headache onset and ED presentation was 84 hours, being different in patients with associated symptoms (48 hours) when compared with isolated headache patients (168 hours). Time since ED presentation and the diagnosis also differed between the 2 groups, being more prolonged in patients with an isolated headache at presentation.Headache attributed with CVST did not exhibit any distinctive phenotype, but all the patients presented some red flag, being abnormal neurological examination the most frequent.

Abstract
Introduction: Despite increasing the use of magnetic resonance imaging (MRI), cerebral venous sinus thrombosis (CVST) has remained an under-diagnosed condition. In this study, characteristics and frequency of various risk factors of CVST patients in a tertiary referral hospital were closely assessed. Methods: Patients with an unequivocal diagnosis of CVST confirmed by MRI and magnetic resonance venography during 6 years of the study were included. All data from the onset of symptoms regarding clinical signs and symptoms, hospital admission, seasonal distribution, medical and drug history, thrombophilic profile, D-dimer, neuroimaging, cerebrospinal fluid findings, mortality, and outcome were collected and closely analyzed. Result: A total of 53 patients with female to male ratio of 3.07 and mean age of 33.7 years were included in the study. Headache and papilledema were the most frequent clinical features (44 and 36 patients, respectively). An underlying disease (diagnosed previously or after admission) was the most common identified risk factor for CVST in both females and males (21 patients). A total of 15 women used the oral contraceptive pill (OCP) where 12 of them had simultaneously other predisposing factors. Overall, 19 patients (36%) had more than one contributing factor. D-dimer had a sensitivity of 71.4% in CVST patients. The mortality of patients in this study was 3.7% (n = 2). Focal neurologic deficit and multicranial nerve palsy were associated with poor outcome which defined as death, recurrence, and massive intracranial hemorrhage due to anticoagulation (P = 0.050 and 0.004, respectively). Conclusion: Unlike most of the CVST studies in which OCP was the main factor; in this study, an underlying disease was the most identified cause. Considering the high probability of multiple risk factors in CVST that was shown by this study, appropriate work up should be noted to uncover them.

Abstract
Cerebral venous sinus thrombosis (CVST) is a relatively uncommon cause of stroke more often affecting women and younger individuals. Blockage of the venous outflow rapidly causes edema and space-occupying venous infarctions and it seems intuitive that decompressive craniectomy (DC) can effectively reduce intracranial pressure just like it works for malignant middle cerebral artery infarcts and traumatic brain injury. But because of the relative rarity of this type of stroke, strong evidence from randomized controlled trials that DC is a life-saving procedure is not available unlike in the latter two conditions. There is a possibility that other forms of interventions like endovascular recanalization, thrombectomy, thrombolysis, and anticoagulation, which cannot be used in established middle cerebral artery infarcts and TBI, can reverse the ongoing pathology of increasing edema in CVST. Such interventions, although presently unproven, could theoretically obviate the need for DC when used in early stages. However, in the absence of such evidence, we recommend that DC be considered early as a life-saving measure whenever there are large hemorrhagic infarcts, expanding edema, radiological, and clinical features of impending herniation. This review gives an overview of the etiology and risk factors of CVST in different patient populations and examines the effectiveness of DC and other forms of interventions.

Abstract
The cerebral venous system is an unusual site of thrombosis, with a particularly high incidence in young adults. This incidence has increased in past decades because of the improvement of neuroradiological techniques. Risk factors for cerebral venous sinus thrombosis overlap with those of other venous thromboembolism sites; however, some are specific for this particular anatomical district. Prognosis is favorable in most cases if diagnosis is made rapidly and treatment is promptly initiated, even if acute complications or chronic invalidity still occur in a quarter of patients. The mainstay of treatment is anticoagulation, which is necessary in order to block clot propagation and obtain recanalization. Intracranial bleeding does not contraindicate anticoagulation. Endovascular procedures are reserved for patients with a particularly severe presentation or rapidly declining neurological symptoms despite appropriate anticoagulation, although data from clinical trials are lacking. Specifically, this review addresses the epidemiology, clinical presentation and course, risk factors, and treatment of cerebral venous sinus thrombosis, with a special focus on the pediatric population.

Abstract
BACKGROUND We analysed differences in hospitalization rates for venous diseases such as pulmonary embolism (PE), deep vein thrombosis (DVT), sinus vein thrombosis (SVT), portal vein thrombosis (PVT), and Budd-Chiari syndrome (BCS) as well as for arterial diseases such as myocardial infarction (MI) and embolic stroke (ES) in females and males aged 10 to 39 years. PATIENTS AND METHODS Detailed lists of hospitalizations with the principal and additional diagnoses for PE (ICD-code I26.0 + I26.9), DVT (I80.0-I80.9), SVT (I67.6), PVT (I81), BCS (I82.0), MI (I21.0-I21.9), and ES (I63.1 + I63.4) in males and females aged 10 to 39 years in the years 2006 to 2015 were provided by the Federal Statistical Office in Germany. RESULTS Considering the 10-year period there were more female than male cases hospitalized with the principal diagnoses for PE, DVT, SVT, and BCS. Looking at the principal diagnosis of the year 2015, one can see a steep increase in numbers of hospitalization for PE, DVT, and SVT in females ranging from the ages 12 to 13 and 14 to 15 years compared to males. The curves of PE and DVT meet again in the age group between 32 and 33 years, but not for SVT. The greatest differences are seen at the end of the second and at the beginning of the third decade of life. In contrast, MI was more frequent in young males beginning at the age of 18 to 19 years. The number of female and male cases with ES and PVT were almost similar in the different age groups. CONCLUSIONS The presented data show higher hospitalization rates for females in the age group 10 to 39 years for different venous thrombosis but not for MI and ES.

Abstract
Cerebral venous sinus thrombosis (CVST) is a rare ischemic cerebrovascular disease. The aim of this retrospective observational study was to investigate the risk factors for complication of cerebral venous sinus thrombosis by seizures and to explore the impact of such seizures on clinical outcomes. Patients with cerebral venous sinus thrombosis with or without epileptic seizures were retrospectively analyzed and compared in terms of clinical variables, causative factors, clinical presentation, and imaging data. In all, 69 patients with cerebral venous sinus thrombosis were enrolled in this study, 32 (46.38%) of whom had experienced secondary seizures. Compared with those with no seizures, significantly more patients with secondary seizures had hemiplegia (37.50 vs. 15.63%; P = 0.020), bleeding (29.40 vs. 10.81%; P = 0.047), lesions involving the frontal (31.25 vs. 10.81%; P = 0.023) and temporal lobe (43.75 vs. 8.11%; P = 0.005), and thrombosis in the superior sagittal sinus (65.63 vs. 40.54%; P = 0.036). Multivariate logistic regression analysis showed focal neurological deficits (P = 0.004, odds ratio = 5.16, 95% CI 1.99–15.76) and thrombosis of the superior sagittal sinus (P = 0.039, odds ratio = 0.13, 95% CI 0.04–0.37) were independent risk factors for secondary seizures in patients with cerebral venous sinus thrombosis. In addition, mortality rate (9.38 vs. 5.41%; P = 0.469) and 90-day excellent prognosis rate (81.25 vs. 86.47%; P = 0.793) did not differ significantly between patients with and without epileptic seizures. The presence of focal neurological deficits and thrombosis of the superior sagittal sinus are independent risk factors for secondary seizures in patients with cerebral venous sinus thrombosis, whereas mortality and 90-day prognosis have no correlation with secondary seizures.

Abstract
A case of 43-year-old female presented to the emergency department (ED) with a new onset grand mal tonic-clonic seizure lasting at least two minutes with post-ictal confusion. Imaging was consistent with cerebral sinus venous thrombosis (CSVT) associated with intracranial hemorrhage. After ruling out most common causes of thrombosis, the etiology was attributed to estrogen vaginal ring. The patient was treated with anticoagulation therapy and had increasing hemorrhagic changes in the first few days, which eventually improved. The estimated annual incidence of cerebral sinus vein thromboses is approximately 3-4 cases per 1 million adults, mostly occurring in females. More than 80% of patients have favorable neurologic outcomes due to increased awareness of the condition as well as availability of advanced imagining and treatment options. The treatment is still controversial due to the high risk of intracranial hemorrhage with sinus thrombosis, especially for patients on anticoagulation. Still, most guidelines support starting anticoagulation. In this report, we highlight the association of CSVT with estrogen vaginal ring and discuss recent management recommendations per different society guidelines.

Abstract
BACKGROUND AND PURPOSE Cerebral venous thrombosis (CVT) affects venous hemodynamics and can provoke severe stroke and chronic intracranial hypertension. We sought to comprehensively analyze 3-dimensional blood flow and hemodynamic alterations during acute CVT including collateral recruitment and at follow-up. METHODS Twenty-two consecutive patients with acute CVT were prospectively included and underwent routine brain magnetic resonance imaging (MRI) and 4-dimensional flow MRI at 3 T for the in vivo assessment of cerebral blood flow. Neurological and MRI follow-up at 6 months was performed in 18 patients. RESULTS Three-dimensional blood flow visualization and quantification of large dural venous sinuses and deep cerebral veins was successfully performed in all patients. During acute CVT, we observed abnormal flow patterns including stagnant flow, flow acceleration in stenoses, and change of flow directions. In patients with complete recanalization, flow trajectories resembled those known from previously published 4-dimensional flow MRI data in healthy adults. There was a trend toward a relationship between occluded segments and cerebral lesions (not significant). Furthermore, patients with versus without cerebral lesions showed increased mean (0.08±0.09 versus 0.005±0.014 m/s) and peak velocities (0.18±0.21 versus 0.006±0.02 m/s) within partially thrombosed left and right transverse sinuses (P<0.05) at baseline. CONCLUSIONS Four-dimensional flow MRI was successfully applied for the 3-dimensional visualization and quantification of venous hemodynamics in patients with CVT and provided new dynamic information regarding vessel recanalization. This technique seems promising to investigate the contribution of hemodynamic parameters and collaterals in a larger cohort to identify those at risk of stroke.

Abstract
Cerebral venous sinus thrombosis (CVST) is a distinct cerebrovascular disorder, and ~50% of CVST patients progress to cerebral venous infarction, resulting in elevation of cerebral venous pressure. Anticoagulation is the standard initial treatment and is associated with a reduced relative risk of mortality and dependency. Recombinant human soluble thrombomodulin (rhs‑TM) is a promising therapeutic natural anticoagulant comparable to antithrombin, tissue factor pathway inhibitor, and activated protein C. The present study aimed to investigate the protective effects of rhs‑TM in a CVST rat model, and identify any underlying mechanisms. Rats were treated with rhs‑TM intravenously prior to CVST. Following neurological function evaluation, animals were sacrificed and brain water content and infarct volume were assessed. Brain tissue was collected from the infarcted segments and mRNA and protein expression levels of high mobility group box 1 (HMGB1), receptor for advanced glycation end products (RAGE), tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β, IL‑6, caspase‑3, B‑cell lymphoma‑2 and Bcl‑2 associated X were analyzed by reverse transcription-quantitative polymerase chain reaction and western blot analysis. rhs‑TM significantly prevented neurological deficits in locomotor function and reduced infarct volume. The expression levels of HMGB1‑RAGE were upregulated in the infarcted segments of rat brains following CVST. Pretreatment with rhs‑TM inhibited the HMGB1‑RAGE axis, alleviating the expression levels of the proinflammatory cytokines, TNF‑α, IL‑1β and IL‑6; however, expression levels of the apoptosis-associated genes and proteins remained unaffected. The results of the present study indicated that rhs‑TM protects against CVST in the rat model via inhibition of the HMGB1‑RAGE axis and inflammation, but not via apoptosis.

Nephrotic Syndrome May Be One of the Important Etiologies of Cerebral Venous Sinus Thrombosis. J Stroke Cerebrovasc Dis 2016; 25:2415-22.

Abstract
OBJECTIVE Thrombosis is a common complication of nephrotic syndrome (NS). However, cerebral venous sinus thrombosis (CVST) secondary to NS is rarely reported. Here we report a case series study of 5 cases of CVST with NS, so as to make a better understanding and management of this disorder. METHODS A retrospective study was performed in 5 consecutive patients with CVST in combination with NS between 2009 and 2015. The clinical manifestations, laboratory and radiological findings, treatment, and clinical outcomes were analyzed. RESULTS This cohort of case series consists of 1 woman and 4 men, aged 16-49 years. All patients complained initially of an acute or subacute headache. CVST attacked during NS occurrence in 3 patients, and during NS recurrence in 2 patients. The median duration of signs and symptoms prior to clinical diagnosis and treatment was 12.80 ± 7.53 days. In all patients, it was magnetic resonance venography that detected the thrombosis in the cerebral venous sinus, with the most common site of CVST to be the superior sagittal sinus (5 of 5 patients). Two or more segments of sinus were involved simultaneously in 4 patients. The treatment of CVST in NS involved therapy of CVST in the general population. All the 5 patients had full recovery, and no one relapsed with a follow-up of 26.60 ± 29.75 months. CONCLUSIONS NS may be one of the important etiologies of CVST. When patients with NS had progressing headache, seizure, or other unexplained neurological symptoms, CVST should be considered.

Abstract
OBJECTIVE The purpose of this study is to assess the performance of routinely used MRI sequences with and without contrast enhancement in the diagnostic evaluation of dural venous sinus thrombosis (DVST). MATERIALS AND METHODS We identified consecutive patients older than 18 years who underwent concurrent standardized brain MRI and contrast-enhanced (CE) MR venography (MRV) examinations for suspected DVST. The seven MRI sequences that were used (axial unenhanced T1-weighted, T1-weighted CE, T2-weighted, DWI, T2-weighted FLAIR, T2-weighted gradient-recalled echo [GRE], and sagittal 3D T1-weighted GRE CE sequences) were randomized, anonymized, and reviewed independently by two neuroradiologists who were blinded to the final diagnosis. Ten separate venous sinus segments were evaluated. CE MRV was the reference standard for determining the presence or absence of DVST, and it was performed using the following imaging parameters: TR/TE, 4.1-77/1.4-9.5; flip angle, 12-35°; and slice thickness, 0.8-1.4 mm. The diagnostic performance of and interobserver variability for each sequence was assessed per patient and per segment. RESULTS Thirty-six patients with DVST (72% of whom had acute thrombosis and 28% of whom had chronic thrombosis) and 29 patients without DVST were included in the study. For each sequence, the AUC values for the detection of DVST per patient, as determined by reviewer 1 and reviewer 2, respectively, were as follows: for T1-weighted unenhanced sequences, 55% and 61%; for T1-weighted CE sequences, 79% and 80%; for T2-weighted sequences, 77% and 76%; for DWI sequences, 59% and 64%; for T2-weighted FLAIR sequences, 70% and 72%; for T2-weighted GRE sequences, 64% and 66%; and for the 3D T1-weighted GRE CE sequence, 77% and 81%. The diagnostic performance of the 3D T1-weighted GRE CE sequences was statistically significantly greater than that of the other sequences. Interobserver variability ranged from 0.26 (for T1-weighted unenhanced sequences) to 0.73 (for the DWI sequence). Overall, for each reviewer and with the use of all evaluated sequences, MRI had a high sensitivity (> 99% for both reviewers) but low specificity (14% for reviewer 1 and 48% for reviewer 2) for the detection of DVST. CONCLUSION Sequences used in routine brain MRI performed with and without contrast enhancement have varying strengths that are important to recognize when the likelihood of DVST is assessed, but they do not replace the utility of dedicated CE MRV.

Abstract
BACKGROUND Head injury is a risk factor for cerebral sinovenous thrombosis (CSVT) in children. Literature concerning head injury-associated CSVT (HIA-CSVT) is scarce. Data supporting safety and efficacy of anticoagulant therapy (ACT) in childhood CSVT is emerging. However, intracranial hemorrhage (ICH) occurs frequently in children with HIA-CSVT at diagnosis making initiation of ACT controversial due to the fear of worsening of ICH. PROCEDURE We conducted a retrospective descriptive review of a consecutive cohort of children with HIA-CSVT from 1998 to 2012. RESULTS Twenty patients (14 males, mean age 7 years) with HIA-CSVT were identified. Most (19/20 [95%]) had significant ICH at diagnosis. None received ACT at diagnosis. Fourteen (70%) were later (median 7 days post-trauma, range 2-48 days) treated with ACT due to CSVT persistence (nine) and propagation (five), despite ICH in 13. None of the treated patients, including the 13 with pre-existing ICH, had significant worsening of hemorrhage. Three (21%) treated patients had minor asymptomatic extension of their hemorrhage and further ACT was withheld. No patient died while on ACT. No patient experienced CSVT propagation on ACT. Clinical outcomes were normal (no neurologic deficits) in 5/20(25%), mild neurological deficits in 10/20(50%), and moderate-severe neurological deficits in 5/20(25%). Small sample size did not permit assessment of the effect of ACT on outcome. CONCLUSIONS Anticoagulant therapy is safe in selected children with HIA-CSVT. ICH is not an absolute contraindication to ACT in children with HIA-CSVT.
