Abstract

Objective: Determine the imaging characteristics and risk factors of superior sagittal sinus thrombosis. Subjects: 40 patients  were diagnosed with superior sagittal sinus thrombosis at Bach Mai Hospital during January 2015 to October 2016. Methods: cross-sectional descriptive study. Results: 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 proportion. In contrast, on MRI, the most common lesion was haemorrhagic transformation of cerebral infarction (40,6%). The proportion of cases with congenital thrombophilia: Protein S deficiency (10%), ATIII deficiency (10%), Protein C deficiency (5%). There were 22 female out of 40 selected patients, the proportion of postnatal, pregnancy and oral contraception using patients were 22,7%, 18,2% and 13,6%, respectivesly. Conclusions: The disease’s imaging findings are non-specific and variable including haemorrhagic transformation of cerebral infarction, cerebral haemorrhage, cerebral infarction and subarachnoid haemorrhage. Acquired and congenital of thrombophilia appears to be an important additional risk factor.
