[摘要] 目的：探讨CT血管成像(CTA)对髂静脉受压综合征(IVCS)及继发血栓形成的诊断价值。方法：选择本院经下肢静脉血管造影(DSA)证实的髂静脉受压综合征患者30例作为观察组，选择因其他病行下腹部及盆腔CTA检查的患者30例作为对照组，比较两组髂静脉内径及受压程度。结果：观察组患者受压髂静脉前后内径为左侧(2.7±1.3)mm，右侧(2.6±1.2)mm，对照组患者对应髂静脉前后内径为左侧(7.3±1.5)mm，右侧(7.8±2.1)mm，两组差异有统计学意义(t=11.35、12.46，P<0.05)。观察组30例患者CTA诊断与DSA检查结果一致，其中，左髂总静脉受压26例，右髂静脉受压4例，其中，14例患者继发血栓形成。结论：CTA检查与DSA检查的一致性较高，并且无创方便，可以准确显示受压髂静脉内径及受压程度及下肢静脉继发血栓情况，值得应用。

[Abstract] Objective: To evaluate the diagnosis value of CT angiography(CTA) in iliac vein compression syndrome (IVCS) and secondary thrombosis. Methods: 30 cases of IVCS patients confirmed in our hospital were selected as observation group, 30 cases of patients with lower abdominal and pelvic CTA were selected as control group. Inner diameter and pressure level of the iliac vein were compared. Results: The left and right of inner diameters of observation group were (2.7±1.3) mm, (2.6±1.2) mm, inner diameter of control group were (7.3±1.5) mm，(7.8±2.1) mm, the differences were statistically significant (t=11.35, 12.46, P<0.05). CTA diagnosis of observation group was consistent with DSA, of which 26 cases with left iliac vein compression, 4 cases with right iliac vein compression, and 14 patients with secondary thrombosis. Conclusion: CTA examination can show the inner diameter of the iliac vein and secondary thrombosis accurately, and it has higher consistency with DSA, so it is worthy of application.

髂静脉受压可造成静脉回流障碍、下肢静脉高压、下肢静脉瓣膜功能不全和浅静脉曲张，甚至继发髂-股静脉血栓。髂静脉受压综合征(IVCS)是指髂静脉受压和(或)存在腔内异常粘连结构所引起的下肢和盆腔静脉回流障碍性疾病。静脉血管造影(DSA)在显示病变血管的同时还可以显示侧支循环情况，目前临床应用较广，成为诊断IVCS的主要标准。CT血管成像(CTA)具有无创性，并且分辨率高，显像清晰。尤其是强大的后期图像处理功能[1-2]，目前临床应用越来越多。笔者选择本院近年收治的IVCS患者30例，探讨CTA在IVCS及继发血栓中的诊断价值。现报道如下：
