Thoraco-abdominal Aorta Revascularization through a Retroperitoneal Approach

Objective To investigate the application of the retroperitoneal approach in aortic surgery. Methods We collected and analyzed data of 7 patients in Macau who presented with aortic diseases from 2007 to 2008 and were treated with aorta repair through retroperitoneal approach. Demographic features as well as intraoperative and postoperative data were analyzed. One case of thoracoabdominal aneurysm and 4 cases of abdominal aneurysm received artificial graft, among which hybrid iliac artery reconstruction with Zenith stent covering the ostium of the left subclavian artery was performed in 2 cases of infrarenal abdominal aneurysm. Aortic-iliac artery bypass was performed in 2 cases of aortoiliac occlusion. Results No operative or early postoperative death was observed. No perioperative intestinal adhesion or ureteral obstruction was found. One case reported delayed paraplegia and graft infection as postoperative complications. The complications were partially removed 3 months later after rehabilitation. Conclusion Retroperitoneal approach is a safe and feasible technique, which associated with a low incidence of postoperative pulmonary complications.
