Abstract:Objective:To analyze the operative effect of carotid-subclavian bypass grafting for subclavian artery occlusion.
Methods :Seventeen patients with subclavian artery disease were diagnosed by arteriography and received carotid-subclavian bypass grafting. Graft patency was determined by Duplex ultrasound scan examinations.
Results:All 17 patients undergoing bypass grafting achieved immediate relief of symptoms. The blood pressure differences between the treated and the healthy arms were less than 10 mmHg after operation. The ratio of healthy/diseased side of the mean blood pressure index increased from 0.64±0.12 preoperatively to 0.98±0.10 postoperatively (P＜0.01). No perioperative stroke or death occurred. By 7.1 years of the mean follow-up, the patency rate at 1 and 5 years was 100% and 94.1%,respectively.
Conclusions:Carotid-subclavian bypass grafting for subclavian artery disease has shown to be very safe and effective, and with excellent long-term patency. We think it shoud be offered to good-risk surgical candidates who may be seeking a more durable procedure.
