人造血管搭桥旁路转流术治疗主髂动脉闭塞症

Synthetic Grafts for By-pass Operation in Aortoiliac Occlusive Atheromatous Disease

人造血管搭桥旁路术治疗主髂动脉硬化闭塞症5例，无手术死亡，临床症状消失或好转4例，随访1～4年人造血管通畅率80％。多普勒血流仪节段性测压是一简便易行，对诊断治疗和预后均有价值的检查方法。踝／肱指数＜0.5时，应及时手术，挽救肢体。股浅动脉阻塞，将影响人造血管的长期通畅率，可以行股深动脉成形术，改善肢体血供。

The authors report 5 cases of aortoiliac atheromatous occlusive disease treated by synthetic graft bypass without mortality during the operation. Clinical occlusive signs disappeared or improved in 4 cases after 1 to 4 year follow-up. The patent rate was 80% in all cases. Measurement of the vascular pressure gradient by Doppler ultrasound is the easy way which plays a good role in the diagnosis, treatment and prognosis. When ark1e brachial pressure index(A/B index)is <0. 5,it is necessary to operate upon rather early to rescue the extremity. If superficial femoral artery is obstructed, the long-term cumulative patency rate will be decreased. In order to improve the blood supply of the extremities in these cases, Profunda femoral artery angioplasty can be performed.
