Abstract

Objective: To determine the clinical characteristics and risk factors of superior sagittal sinus thrombosis. Subjects: We selected 40 patients diagnosed as superior sagittal sinus thrombosis at Bach Mai Hospital from January 2015 to October 2016. Methods: cross-sectional descriptive study. Results: The common symptoms of superior sagittal sinus thrombosis in this study were headache (95%), paralysis (32,5%), seizure (20%), consciousness disorder (20%), sensory disorder (15%), cranial nerves palsy (15%). The most common finding of brain damage on the imaging of computed tomography was cerebral haemorrhage (37,5%), followed by cerebral infarction and subarachnoid haemorrhage, haemorrhagic transformation of cerebral infarction accounted for lowest percentage. In contrast, on MRI, the most common lesion was haemorrhagic transformation of cerebral infarction (40,6%). The proportion of cases with congenital thrombophilia was Protein S deficiency (10%), ATIII deficiency (10%), Protein C deficiency (5%). Conclusions: Cerebral venous thrombosis in general  and superior sagittal sinus thrombosis in particular is a challenging condition because of its variability of symptoms and signs. The spectrum of clinical and paraclinical presentations was non-specific and variable.
