Control of the upper infrarenal aorta.
Variations in technique used to control the infrarenal aorta in a variety of circumstances are described. Usually direct clamping of the aorta below the renal arteries is appropriate. Alternatives include suprarenal, supracoeliac, and intrathoracic clamping, balloon catheters and external pressure. Renal vein ligation improves access to the infrarenal aorta but in the occasional patient produces renal congestion.
