Radiographic Findings of Cerebral Venous Thrombosis in Roi-Et Hospital

Abstract

         With its highly variable clinical presentation, the diagnosis of cerebral venous sinus thrombosis (SVT) and deep venous thrombosis (DVT) is challenging.

The aims of this study was to determine the radiographic findings detected by magnetic resonance imaging in Roi-Et hospital of cerebral venous thrombosis. A retrospective review of patient who had magnetic resonance imaging performed for cerebral venous thrombosis detection, between August 2013 to August 2015 by using PACS to access imaging features, location, and extension. Sensitivity of non contrast CT scan and contrast enhanced CT in determine cerebral venous thrombosis were calculated.

Twenty patients with cerebral veins thrombosis were reviewed. The most common radiographic findings was intracerebral hemorrhage, and cerebral infarction, eleven patients (55%). Twelve patients (60%) had had subacute clot. The most common location of cerebral venous thrombosis is superior sagittal sinus, fourteen patients (70%) and cortical vein, ten patients (50%). Most of them had multiple location of thrombosis. Sensitivity of non contrast CT to identified cerebral venous thrombosis (cord sign or attenuated vein sign) was 92.8% and sensitivity of contrast enhanced CT was 100%. On MRI, the sequence that had highest sensitivity to detected cerebral venous thrombosis was contrast enhanced MRV, 19 patents (95%) and gradient images, 16 patents (80%). Most common symptoms of cerebral venous thrombosis patient was headache, twelve patients (60%) and weakness, eleven patients (55%) presented with weakness.

In conclusion the most common radiographic finding of cerebral venous thrombosis was cerebral infarction and hemorrhage, most common location of the thrombosis was superior sagittal sinus in subacute stage with high detection rate from CT with and without contrast
