| 摘 要： | 目的探讨CT静脉造影(CTV)在脑静脉窦血栓形成(CVST)诊断中的价值。方法对16例CVST患者行脑CTV检查,在工作站处理获得二维和三维血管重建图像。结果窦腔内充盈缺损在CTV横断层图像上表现为"空三角征"。16例中11例为多发性CVST,其中8例以上矢状窦受累为主,3例以横窦受累为主;5例为单一静脉窦受累,其中2例为上矢状窦、2例为直窦、1例为下矢状窦。16例二维或三维重建图像均可见静脉窦不规则狭窄或闭塞,静脉属支不同程度扩张。11例出现脑水肿,6例出现脑梗死,4例发生脑出血。结论CTV对CVST诊断具有很高的敏感性和特异性。

| 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 sim... |
