Cerebral Venous Sinus Thrombosis in Inflammatory Bowel Disease: A Review of Published Case Reports.

Cerebral venous sinus thrombosis (CVST) is a rare extraintestinal manifestation of inflammatory bowel disease (IBD), and the risk of poor clinical outcomes remains high in patients with delayed CVST diagnoses. This study aimed to highlight the need to recognize the critical nature of CVST complications in IBD and the challenges associated with managing concurrent conditions. We retrospectively reviewed previously reported cases of CVST in patients with IBD by searching the PubMed, Web of Science, and Google Scholar databases for articles published between 2013 and 2020. Our search identified 35 cases of IBD complicated by CVST. The mean patient age was 24.6 years (range, 31 months-47 years; men > women, ratio, 1.18:1). CVST was 3.8 times more common among patients with ulcerative colitis than among those with Crohn's disease. Active IBD was reported in 91.4% of patients. The mean interval between IBD diagnosis and CVST occurrence was 3 years (range, 2 days-16 years). Headache was the most frequently reported symptom (85.7%), and involvement of multiple sinuses was reported in almost two-thirds of the patients. Corticosteroid therapy at the time of the CVST event was the most common prothrombotic risk factor, present in 57.14% of patients. The overall recovery rate after treatment was 77.14%; whereas the bleeding complication rate was 10%. This review provides essential information that can aid clinicians in making earlier diagnoses and promotes preventive strategies for CVST in patients with IBD. Given that CVST management can be challenging in these patients, a multidisciplinary approach is warranted.
