Hybrid procedures for complex thoracoabdominal aortic aneurysms

Although surgical repair of thoracic (TAA) and thoracoabdominal aortic aneurysms (TAAA) is an effective therapeutic option with excellent long-term results, it is also a potentially problematic procedure, owing both to the technical difficulties of aortic reconstruction and to the stress suffered by patients, who are often elderly and afflicted by multiple comorbidities [1]. Also, despite progress in operative techniques in recent years, anatomically challenging aneurysms involving visceral and renal arteries are still associated with high mortality and significant spinal-cord complications [2]. As a result, morbidity and mortality rates are still rather high, especially in patients at high risk for conventional surgical repair [1, 3].
