In this report the long-term experience with 59 patients is presented. Methods Between June 1998 and September 2008, we used endovascular therapy to treat 61 subclavian arterial obstructive lesions in 59 patients （46 males and 13 females, 34-82 years of age with a mean age （61.9~11.0） years）. Twenty patients （34%） had clinical symptoms due to vertebrobasilar insufficiency, 26 （44%） had disabling arm ischemia, and 13 （22%） had both symptoms. We performed all procedures under local anesthesia. The approaches were from the femoral artery （n=47）, brachial artery （n=-1, involving bilateral subclavian disease） or both （n=11）. Sixty stents were implanted. All patients were followed-up at 1,3, 6, and 12 months post-procedure, and annually thereafter. Results We achieved technical success in 58 （95.1%） arteries, all of which were stented. There were three technical failures; two were due to the inability to cross over an occlusion, necessitating the switch to an axillo-axillary bypass, and the third was due to shock after digital subtraction angiography and prior to stenting. Arterial stenosis pre- and post-stenting was （83.6±10.8）% and （2.5±12.5）% （P 〈0.01）. Clinical success was achieved in 55 of the 59 patients （93.4%）. Of the four clinical failures, three were technical and the remaining patient had a stent thrombosis. Systolic blood pressure difference between the two brachial arteries was （44.7±18.5） vs. （2.2±3.9） mmHg （P 〈0.01）. Primary patency was 98% at 12 months, 93% at 24 months, and 82% at 5 years. Five patients were lost to follow-up by 12 months post-stenting. Significant recurrent obstruction developed in five patients with resumption of clinical symptoms. The overall survival rate was 98.2% at 12 months, 89.5% at 24 months, and 84.5% at 5 years. Conclusions Endovascular therapy for proximal subclavian arterial obstructive lesions is e展开更多

In the patients with subclavian steal syndrome the subclavian artery is fed by retrograde flow from the vertebral artery via the carotids and the circle of Willis.展开更多
