Suprarenal Aortic Cross-Clamping in Elective Abdominal Aortic Aneurysm Surgery

Abstract

this data shows that suprarenal clamping, which is necessary for the radical treatment of juxtarenal aortic aneurysms, can be performed with a low risk.

Suprarenal Clamping Is a Safe Method of Aortic Control when Infrarenal Clamping Is not Desirable

“…Giulini et al 20 compared suprarenal clamping for juxtarenal aneurysms and infrarenal clamping for regular AAA. Their perioperative mortality was 3.6% for the suprarenal group vs. 1.9% for the infrarenal one, which did not represent a statistically significant difference.…”

Postoperative Renal Function After Elective Abdominal Aortic Aneurysm Repair Requiring Suprarenal Aortic Cross-Clamping

“…[10][11][12] Between 0% and 40.5% of patients who undergo elective AAA repair suffer transient renal failure after suprarenal aortic cross-clamping. [1][2][3][4][5][6][13][14][15][16] Crawford et al reported that renal failure was the most common complication in their series of 101 juxta-and infrarenal AAAs, and the most common cause of early death, accounting for 63% (5/8) of deaths. 1 One of the major determinants of postoperative renal dysfunction is preexisting renal insufficiency.…”

Preconditioning With Oxygen Attenuates Rat Renal Ischemia–Reperfusion Injury

“…It complicates both surgical repair of ruptured and nonruptured abdominal aortic aneurysms [2,3] and not only open repair of abdominal aortic aneurysms but also endovascular technique is associated with a significant degree of IR injury [4]. The overall incidence rate of ARF after vascular surgery has been reported to be 1.7 to 25% [5].…”
