Abstract:
In the study, we sought to retrospectively analyze the effectiveness and safety of surgical repair of thoracoabdominal aortic aneurysm using the critical artery reattachment technique. Twenty-three consecutive thoracoabdominal aortic aneurysm patients were treated using the technique of sequential aortic clamping and critical artery reattachment. The entire procedure was technically successful in all patients. One died of renal failure and the overall hospital mortality was 4.35%. The total incidence of complications was 21.74%. At a median follow-up of 33 months, all patients were alive. We found that the application of critical artery reattachment technique in the management of thoracoabdominal aortic aneurysm provides excellent short- and mid-term results in most patients. It could markedly increase the curing rate and reduce the morbidity of postoperative complications including paraplegia, ischemia of abdominal viscera, and renal failure.
