头臂供血动脉狭窄和闭塞的经皮血管内成形术治疗

Percutaneous Transluminal Angioplasty for Treating Stenoses of the Brachiocephalic Arteries

头臂供血动脉狭窄，尤其是锁骨下动脉和椎动脉狭窄可以通过经皮血管内成形术（ＰＴＡ）治疗达到满意疗效。１３４例此类患者中的１２５例（９３％）经ＰＴＡ治疗获得早期治疗效果，追踪复查的８４例患者除１例复发狭窄外，其余８３例（９８．８％）获得中长期疗效。头臂供血动脉闭塞的ＰＴＡ疗效欠佳。

Stenoses of the brachiocephalic arteries ,particularly the subclavian and vertebral arteries, can be successfully treated by percutaneous transluminal angioplasty(PTA).In 125 of the 134 patients primary success was achieved by PTA(93%).Among them 84 patients have been followed up for an average of 4. 6 months. All these patients, except one with re-stenosis, were symptomless, showing a clinical cure rate of 98.8%. PTA for occlusions of supra-aortic vessels has less chances of success.
