Background And Objectives: Cerebral venous thrombosis (CVT) is a rare cause of stroke. While the standard treatment is anticoagulation, the type and duration of anticoagulation depends on the underlying etiology. This study aims to identify prevalence, risk factors, and recurrent venous thromboembolism (VTE) rates among patients with idiopathic (cryptogenic) CVT and CVT provoked by transient (peripartum, hormonal treatment, infection, trauma) and persistent (cancer, thrombophilia) factors.

Article Synopsis
  • Cervical artery dissection (CeAD) is a leading cause of ischemic strokes in young adults, and this study explored the effects of intravenous thrombolysis (IVT) on patients with CeAD and stroke symptoms.
  • Analyzed data from the STOP-CAD study, it found that IVT significantly improved functional independence after 90 days in patients without increasing the risk of symptomatic intracranial hemorrhage.
  • The results suggest that IVT is a beneficial treatment for eligible patients with CeAD, aligning with current medical guidelines on its use.

Nearly one fifth of patients with venous thromboembolism (VTE) have cancer. When both of these conditions occur, especially in cases of cerebral vein thrombosis (CVT), patient management is often challenging. The aim of this study was to compare the characteristics and event courses in patients affected by CVT with and without cancer.

Article Synopsis
  • This study looked at patients who had a type of serious stroke called large vessel occlusion (LVO) and how their past health problems affected their recovery after a specific treatment called endovascular therapy (EVT).
  • Researchers checked the medical history and data of nearly 1,000 patients over five years to see how many had previous health issues and how they did after treatment.
  • They found that patients with more past vascular problems had a higher chance of dying or not being independent after three months, and men had more bleeding complications than women during their hospital stay.

The European Stroke Organisation (ESO) guideline on Primary Angiitis of the Central Nervous System (PACNS), developed according to ESO standard operating procedures (SOP) and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology, was elaborated to assist clinicians in the diagnostic and treatment pathway of patients with PACNS in their decision making. A working group involving vascular neurologists, neuroradiologists, rheumatologists, a neuropathologist and a methodologist identified 17 relevant clinical questions; these were addressed according to the patient/population, intervention, comparison and outcomes (PICO) framework and systematic literature reviews were performed. Notably, each PICO was addressed with respect to large vessel (LV)-PACNS and small vessel (SV)-PACNS.

Background Identifying factors associated with delayed diagnosis of cerebral venous thrombosis (CVT) can inform future strategies for early detection. Methods and Results We conducted a retrospective cohort study including all participants from ACTION-CVT (Anticoagulation in the Treatment of Cerebral Venous Thrombosis) study who had dates of neurologic symptom onset and CVT diagnosis available. Delayed diagnosis was defined as CVT diagnosis occurring in the fourth (final) quartile of days from symptom onset.

Article Synopsis
  • The study investigates the effectiveness of endovascular therapy (EVT) compared to intravenous thrombolysis (IVT) in patients with a minor acute ischemic stroke and large vessel occlusion, specifically focusing on the National Institutes of Health Stroke Scale (NIHSS) scores.
  • Data was collected from 533 patients treated between 2005 and 2021, showing that while 25.5% received bridging therapy, only facial palsy on admission associated more with excellent outcomes in those receiving IVT alone.
  • The analysis concluded that NIHSS subitems were not significant predictors of patients who would benefit from EVT over IVT alone, indicating a need for further research in this area.

Five recently published RCTs (MR CLEAN, EXTEND-IA, SWIFT PRIME, REVASCAT and ESCAPE) employing mechanical thrombectomy with modern stent retriever devices clearly demonstrated the superiority of endovascular treatment compared to thrombolysis alone, which is now considered standard first-line therapy for selected patients with acute severe ischemic stroke and large vessel in the anterior circulation. RCT results led to recommendations outlined in "Mechanical thrombectomy in acute ischemic stroke by ESO-Karolinska Stroke Update 2014/2015, supported by ESO, ESMINT, ESNR and EAN". Moreover, endovascular procedures in the 5 RCTs to date were performed at high-volume referral centers with, in some trials, rigid requirements for the interventionalist to participate, which may have contributed substantially to the excellent results, supporting the concept of centralization of intra-arterial thrombolysis resources and expertise.
