摘要
目的探讨主-髂动脉闭塞伴侧支血管形成的多层螺旋CT血管成像(MSCTA)表现。资料与方法分析9例主-髂动脉闭塞伴侧支血管形成的MSCTA表现。结果9例主-髂动脉完全性闭塞,CTA显示侧支血管主要通过以下三条通路吻合:下位肋间后动脉与旋髂深动脉吻合、腹壁上动脉与腹壁下动脉吻合以及肠系膜下动脉(IMA)远段通过迂曲扩张的Riolan动脉弓与肠系膜上动脉(SMA)形成吻合。结论MSCTA可显示主-髂动脉闭塞患者的主要侧支血管情况。
Objective To evaluate multi-slice CT angiographic (MSCTA) findings of collateral circulation secondary to aortoiliac artery occlusive disease. Materials and Methods MSCTA findings in 9 patients with collateral circulation sec- ondary to aortoiliac artery occlusive disease were analyzed. Results Aortoiliac artery occlusion was demonstrated in all 9 cases. CTA showed subcostal artery anastomosed with deep circumflex iliac artery, superior epigastric artery anastomosed with inferior epigastric artery,and IMA anastomosed with SMA through Riolan arch. Conclusion MSCTA could identify collateral circulation secondary to aortoiliac artery occlusive disease.
