Abstract
Fifteen consecutive patients underwent GORE TAG thoracic branch endoprosthesis repair (November 2022 to January 2024) with transradial left subclavian artery branch cannulation (14/15 [93%]; 60% urgent or emergent). Technical success was 100% and median operative time was 88 minutes. Thirty-day mortality was 0%, 73% were discharged home, and no permanent neurological deficits occurred. One intraoperative brachial artery occlusion was treated with open thrombectomy. Three reinterventions occurred within 1 year, and one non-aorta-related death occurred at 8 months; no late branch occlusions or stent graft failures were observed. Transradial branch cannulation is feasible with low early morbidity rates and acceptable midterm durability.
