Thrombosis within the iliofemoral venous system was diagnosed by computed tomography (CT) in five patients. In three patients thrombosed veins were documented by venography and in all five cases, the presence of venous thrombosis was substantiated by the clinical findings. Venous thrombosis in the iliofemoral veins and inferior vena cava has a typical appearance on CT scans. A thrombosed vein appears dilated with a low density intraluminal content and a high density wall after contrast enhancement. By its anatomic location, a thrombosed vein can be differentiated from other tubular structures such as bowel loops or obstructed ureters which may have a similar appearance.
通过计算机断层扫描（CT）诊断出5例患者存在髂股静脉系统血栓形成。3例患者通过静脉造影记录到血栓形成的静脉，在所有5例病例中，静脉血栓形成均由临床发现证实。髂股静脉和下腔静脉的静脉血栓形成在CT扫描上有典型表现。血栓形成的静脉在增强造影后表现为扩张，腔内内容物密度低，壁密度高。根据其解剖位置，血栓形成的静脉可与其他可能有类似表现的管状结构如肠袢或梗阻的输尿管相鉴别。
