摘要
目的探讨多层螺旋CT直接静脉造影(MSCTV)诊断静脉受阻性病变的临床价值。方法收集35例应用直接MSCTV诊断并经临床证实的静脉受阻性病变患者的临床及影像学资料,研究MSCTV成像方法,分析静脉受阻性病变的影像学表现特征。结果本组共35例患者,其中下肢深静脉血栓19例,上肢深静脉血栓2例,深静脉瘤栓3例,单纯性下肢静脉曲张11例。MSCTV深静脉血栓表现为静脉腔内的充盈缺损,管腔中断,侧支循环形成。深静脉瘤栓表现为静脉腔内和/或腔外软组织肿块影,管腔不规则狭窄并充盈缺损。单纯性下肢静脉曲张表现为静脉血管增多、增粗、纡曲。结论静脉受阻性病变具有一定的MSCT征象,MSCTV对诊断静脉受阻性病变具有较大的临床价值。
Objective To explore the clinical value of direct multi-slice computed tomography venography（MSCTV） in diagnosing venous obstructive disease. Methods The clinical and imaging data of 35 cases of venous obstructive disease diagnosed by MSCTV and confirmed in clinic were reviewed. The imaging features of venous obstructive disease were analyzed. Results There were a total of 35 cases, with 19 cases located in deep venous thrombosis of lower extremity, 2 cases located in deep venous thrombosis of upper extremity, 3 cases located in deep venous tumor thrombus, and 11 cases located in simple vein varicosis of lower extremity. MSCTV manifestations of deep venous thrombosis included filling defect in vein intraluminal, luminal interrupt, and formation of collateral circulation.MSCTV manifestations of deep venous tumor thrombus showed soft tissue mass in the vein cavity and/or extraluminal, irregular filling defect and stenosis in lumen. Simple varicose veins of lower extremity showed increased number of veins, as well as thickening and tortuosity. Conclusion MSCTV manifestations of venous obstructive disease have some specific features, which have great clinical value in diagnosing the diseases.
