AI Article Synopsis
- The study evaluates the outcomes of axillary to carotid bypass surgery in patients with chronic common carotid artery occlusion, focusing on both immediate and long-term results.
- Over a follow-up period of up to 17 years, the procedure demonstrated high graft patency and low complication rates, with no perioperative strokes or deaths reported.
- The findings indicate that this surgical method is a safe and effective treatment option, but further validation in larger, randomized studies is recommended.
Article Abstract
Objective: Relatively little is known about the natural history of atherosclerotic common carotid artery occlusion and optimal treatment of these patients is still unclear. The aim of this retrospective study was to evaluate the immediate- and long-term outcomes of axillary to carotid bypass with polytetrafluoroethylene graft for symptomatic patients with chronic common carotid artery occlusion.
Methods: From March 2001 to December 2017, 58 symptomatic patients (41 men; mean age 64.7 years) with chronic common carotid artery occlusion underwent axillary to carotid bypass at one academic hospital. The clinical data of this patient cohort were retrospectively analyzed. The cumulative graft patency, overall survival, freedom from symptoms, and freedom from ipsilateral stroke were calculated with Kaplan-Meier method.
Results: Thirty-three patients presented with transient ischemic attack and 25 patients presented with minor stroke. At 30 days after bypass, the overall perioperative complication rate was 3.4% (2/58). Mild injuries of brachial plexus occurred in one (1.7%) patient and myocardial infarction occurred in one (1.7%) patient. No perioperative stroke or death occurred. The median follow-up was 51 months (range, 12-203) for this series. The cumulative graft patency rates at 1, 3, 5, and 10 years were 100%, 100%, 94%, and 83%, respectively. The cumulative freedom from symptoms rates at 1, 3, 5, and 10 years were 100%, 100%, 94%, and 75%, respectively. The cumulative freedom from ipsilateral stroke rates at 1, 3, 5, and 10 years were 100%, 100%, 94%, and 82%, respectively. The overall survival rates at 1, 3, 5, and 10 years were 98%, 89%, 81%, and 67%, respectively.
Conclusions: Axillary to carotid bypass with polytetrafluoroethylene graft is safe and durable for symptomatic patients with chronic common carotid artery occlusion. The results of this study should be confirmed with a larger, randomized controlled trial in future.
