Background. Renal failure remains a common complication of thoracoabdominal aortic
aneurysm repair. The purpose of this randomized clinical trial was to compare two methods
of selective renal perfusion—cold crystalloid perfusion versus normothermic blood perfusion—
and determine which technique provides the best kidney protection during
thoracoabdominal aortic aneurysm repair. Methods. Thirty randomized patients undergoing
Crawford extent II thoracoabdominal aortic aneurysm repair with left heart bypass had renal …

Methods. Thirty randomized patients undergoing TAAA repair with left heart bypass (LHB)
had renal artery perfusion with either 4 C lactated Ringer's solution (14 patients) or
normothermic blood from the bypass circuit (16 patients). Acute renal dysfunction was
defined as an elevation in serum creatinine level exceeding 50% of baseline within 10
postoperative days. Results. One death occurred in each group. One patient in the blood
perfusion group developed kidney failure requiring hemodialysis. Ten patients (63%) in the …
