Cerebral Sinus Venous Thrombosis Risk Factors

Prothrombotic Conditions

Inherited thrombophilias, including protein C deficiency (combined odds ratio of 11.1), protein S deficiency, antithrombin III deficiency, and factor V Leiden positivity, are significant risk factors for CSVT, according to the American Heart Association 1, 2
Hyperhomocysteinemia is another significant prothrombotic risk factor for CSVT 1

CSVT shows a bimodal age distribution with peaks in infancy (approximately 20% of pediatric cases) and adolescence (around 50% of cases occurring in ages 11-18), as reported by the International Society on Thrombosis and Haemostasis 3
Overall, CSVT predominantly affects younger individuals, with 78% of cases occurring in patients under 50 years of age, according to the American Stroke Association 1

MRI with MR venography is the preferred initial imaging modality for patients with suspected CSVT, as recommended by the American College of Radiology 4
CT venography can be used when MRI is not readily available, according to the American College of Radiology 4
Catheter angiography may be necessary in cases with high clinical suspicion but negative initial imaging, as suggested by the Society of Interventional Radiology 4
Early identification and appropriate management of CSVT can significantly improve outcomes by preventing thrombus propagation and reducing mortality and disability, as stated by the American Heart Association 5, 4

Genetic causes of thrombophilia, such as factor V Leiden mutation and G20210A mutation of prothrombin, are associated with increased risk, particularly in children and young adults 6
Dehydration can contribute to blood stasis and increased risk 7
