Key result
Suprarenal aortic cross-clamping during juxtarenal abdominal aortic aneurysm repair did not significantly increase the rate of acute postoperative renal insufficiency compared to infrarenal clamping (28.6% vs 15.4%, p=0.22).

Does suprarenal aortic cross-clamping increase the risk of postoperative renal insufficiency compared to infrarenal clamping in patients undergoing open surgery for AAA?
Absolute Event Rate: 28.6% vs 15.4%
p-value: p=0.22
Suprarenal aortic cross-clamping during open AAA repair does not significantly increase the risk of postoperative renal insufficiency compared to infrarenal clamping in patients with similar aneurysmal neck features.
Hoshina et al. (2014) conducted a cohort in Abdominal aortic aneurysm (n=61). Suprarenal aortic cross-clamping vs. Infrarenal aortic clamping was evaluated on Acute postoperative renal insufficiency (eGFR decrease >25%) (p=0.22). Suprarenal aortic cross-clamping during juxtarenal abdominal aortic aneurysm repair did not significantly increase the rate of acute postoperative renal insufficiency compared to infrarenal clamping (28.6% vs 15.4%, p=0.22).
