Postoperative Renal Function Preservation with Non-Ischemic Femoral Arterial Cannulation for Thoracoabdominal Aortic Repair

摘要

Background:Renal failure after thoracoabdominal aortic (TAAA) repair is a significant clinical problem. Distal aortic perfusion for organ and spinal cord protection requires cannulation of the left femoral artery. In 2006 we reported the finding that direct cannulation led to leg ischemia in some patients, and that this was associated with increased renal failure. Following this finding, we modified our perfusion technique to eliminate leg ischemia from cannulation. Here we present the effects of this change on postoperative renal function.
