Key result
Suprarenal cross-clamping for AAA repair shows comparable mortality to infrarenal clamping despite more transient renal insufficiency.
Why the study?
The impact of suprarenal cross-clamping compared to infrarenal cross-clamping on outcomes after elective abdominal aortic aneurysm repair was unclear.

Absolute Event Rate: 2.6% vs 1.2%
William L. Breckwoldt (1992) conducted a cohort in Abdominal aortic aneurysm (n=205). Suprarenal cross-clamping vs. Infrarenal cross-clamping alone was evaluated on Mortality. Suprarenal cross-clamping for abdominal aortic aneurysm repair had comparable mortality to infrarenal cross-clamping (2.6% vs 1.2%), despite more frequent transient renal insufficiency (28% vs 10%).
