ABSTRACT
Objective To explore the value of CT venography (CTV) in diagnosis of cerebral venous sinus thrombosis (CVST) . Methods 16 patients with CVST were examined by CTV. 2D and 3D vascular images were reconstructed through workstation. Results Filling-defect was seen as "empty triangle sign" on the axial image.Multiple CVST were displayed in 11 patients,among them,8 cases involved superior sagittal sinus,3 cases involved lateral sinus. Single CVST was displayed in 5 patients,2 cases involved superior sagittal simes,2 cases involved straight sinus,1 case involved inferior sagittal sinus. The irregular narrowing or occlusion of the sinus and dilation of the branch of vein were observed in all 16 patients on 2D or 3D images. Hydrocephalus, cerebral infarction and cerebral hemorrhage were seen in 11 cases, 6 cases and 4 cases respectively. Conclusion CTV is a sensitive and distinctive technique in diagnosing CVST.
