Abdominal Aortic Aneurysm in a Renal Allograft Recipient A Fig. 1. CT angiographic images revealing (A) right pelvic renal allograft and (B) 6.4 cm sized infrarenal AAA. 167 B Fig. 2. Temporary aortofemoral shunt from the perirenal aorta to the right femoral artery, allowing perfusion of the pelvic renal allo- graft during aortic cross-clamping. lation for a temporary shunt was performed at the level of the perirenal aorta; this shunt was placed in the common femoral artery (Fig. 2). A 16-Fr and a 12-Fr aortic perfusion cannula (Edwards Lifesciences, Irvine, CA, U.S.A.) were used for the temporary shunt, and these two cannulas were con- nected with a 3/8’’ connector. After confirming this tempo- rary shunt’s function, we performed infrarenal aortic cross- clamping. The total aortic cross-clamping time was 34 min Fig. 3.

The aortic and femoral cannulation sites were simply closed with previously placed purse-string sutures. The patient recovered without any com- plications, and the immediate postoperative serum creatinine level was 1.1 mg/dL. During the admission, his serum crea- tinine level remained within normal limits. He was discharg- ed after a 14-day hospitalization, and subsequent CT angio- graphic images showed a well-functioning aortic graft with
