中国医学影像技术 2007年第23卷第12期 Chin J Med Imaging Technol，2007，Vol 23，No 12 · 1813 · MSCT diagnosis of the inferior vena cava diseases ZHANG Long—jiang，YANG Gui—fen，SHEN Wen，QI Ji (Department of Radiology，Tianjin F rst Central Hospital，Tianjin Medical University．Tianjin 300192．China) [Abstract] Objective To assess diagnostic value of multi—detector computed tomography(MSCT)in inferior vena cava (IVC)diseases．Methods Clinical and imaging data of thirty—eight cases suspected of IVC lesions were analyzed retrospec— tively；their MSCT appearances were also summarized，and compared to surgical，DSA，and follow-up data．Results Of thirty—eight cases，6 cases of congenital IVC lesions，4 cases of stenosis or occlusion of IVC。8 cases of thrombosis of IVC． 2 cases of IVC neoplasm，and 1 1 cases of hepatic cancer with invasion of IVC，and other 7 cases were detected on MSCT， which delineated all kinds of IVC lesions in this study．Five patients underwent DSA．25 patients performed surgical resec— tion or exploration because of IVC lesions or other causes，and 2 patients with pulmonary embolism underwent CT follow-uD exam．MSCT findings of IVC lesions were consistent with that of surgery or DSA．Conclusion MSCT has an important role in diagnosing IVC lesions． [Key words] Inferior vena cava；Tomography，X—ray computed；Angiography 多层螺旋CT在下腔静脉病变中的诊断价值 张龙江，杨桂芬，沈 文，祁 吉 (天津医科大学附属第一中心医院放射科，天津 300192) [摘 要] 目的 评价多层螺旋CT(MSCT)在下腔静脉病变中的诊断价值。方法 回顾性分析38例下腔静脉病变的临 床及影像学资料，分析下腔静脉病变的多层螺旋CT表现，并与手术、DSA及临床随访资料进行对照分析。结果 38例中， 下腔静脉先天性异常6例，下腔静脉狭窄和闭塞或布加综合征4例，下腔静脉栓塞性病变8例，下腔静脉肿瘤2例，肝癌l1 例，其他7例。MSCT能很好地显示上述下腔静脉病变。38例病人5例进行血管造影检查，25例因下腔静脉病变或其他 原因进行了手术切除或探查，2例血栓在溶栓治疗后复查时下腔静脉内血栓消失。MSCT显示的下腔静脉病变与手术或 DSA基本一致。结论 MSCT在诊断下腔静脉病变中有重要价值。 [关键词] 下腔静脉；体层摄影术，x线计算机；血管造影术 [中图分类号] R543．6；R814．42 [文献标识码] A [文章编号] 1003—3
