摘要
Objective: We report a single-center experience using the hybrid procedure, consisting of open debranching, followed by endovascular aortic repair, for treatment of arch/proximal descending thoracic/thoracoabdominal aortic aneurysms (TAAA).
Methods:From 2005 to 2010, 51 patients (33 men; mean age, 70 years) underwent a hybrid procedure for arch/proximal descending thoracic/TAAA. The 30-day and in-hospital morbidity and mortality rates, and late endoleak, graft patency, and survival were analyzed. Graft patency was assessed by computed tomography, angiography, or duplex ultrasound imaging.
Results: Hybrid procedures were used to treat 27 thoracic (16 arch, 11 proximal descending thoracic) and 24 TAAA (Crawford/Safi types I to III: 3; type IV: 12; type V: 9). The hybrid procedure involved debranching 47 arch vessels or 77 visceral/renal vessels using bypass grafts, followed by endovascular repair. Seventy-five percent of debranching and endovascular repair procedures were staged, with an average interval of 28 days. Major 30-day and in-hospital complications occurred in 39% of patients and included bypass graft occlusion in four, endoleak reintervention in two, and paraplegia in one Mortality was 3.9%. During a mean follow-up of 13 months, three additional type II endoleaks required intervention, and one bypass graft occluded. No aneurysm rupture occurred during follow-up. Primary bypass graft patency was 95.3%. Actuarial survival was 86% at 1 year and 67% at 3 years.
Conclusion: The hybrid procedure is associated with acceptable rates of mortality and paraplegia when used for treatment of arch/proximal descending thoracic/TAAA. These results support this procedure as a reasonable approach to a difficult surgical problem; however, longer follow-up is required to appraise its ultimate clinical utility.
