Open Surgical Repair of Thoracoabdominal Aortic Aneurysms

Despite much advancement in preoperative evaluation and perioperative care of patients with thoracoabdominal aortic aneurysms (TAAA), open surgical repair of TAAAs remains a formidable challenge for the vascular surgeon. It requires extensive dissection and mobilization of the aorta and its branches, as well as cross-clamping of the aorta above intercostal and visceral arteries. Over the past decade, the mortality and morbidity associated with open TAAA repair have improved significantly. However, it remains one of the most complex, extensive surgical procedures performed in the field of vascular surgery. Recently, there has been much attention directed at less invasive methods such as the so-called “hybrid” or “debranching” procedure, or complete endovascular repair with fenestrated and branched endografts for repairing TAAAs. However, the gold standard for repair of TAAA remains open surgery, and this article summarizes the clinical outcomes of open surgical repair of TAAAs during the past decade (2000–2010) to provide a benchmark for comparison with results from previous decades and also with which to compare the results of modern-day hybrid and/or complete endovascular techniques.
