- W2071737720 abstract "Background We report our 11-year experience of juxtarenal aortic aneurysm (JAA) repair with suprarenal aortic cross-clamping. Methods We retrospectively reviewed 51 consecutive JAA repairs performed between 2000 and 2010. In all 51 patients, aneurysms were replaced by prosthetic grafts with simple suprarenal aortic cross-clamping. No special renal protective measures (except inter-renal cross-clamping) were performed during interruption of perfusion to kidneys. For inter-renal cross-clamping, the aortic cross-clamp was placed from below one renal artery to above the other renal artery to maintain hemilateral renal perfusion. This technique was applied in 27 patients (54%). Postoperative complications, renal function, and survival were evaluated. Results There were no deaths. The average renal ischemia time was 28.9 ± 9.7 minutes. Postoperatively, transient renal failure (defined as an estimated glomerular filtration rate of <30 mL/min/1.73 m2) occurred in 14% of the patients. The postoperative decrease of estimated glomerular filtration rate compared with the preoperative value was significantly smaller in the inter-renal clamp group (7.4% ± 16%) than in the suprarenal clamp group (17.5% ± 16%) (P < 0.05, unpaired t test). However, renal dysfunction was temporary and recovered to baseline before discharge with conservative therapy in all patients except one. In addition, renal function was generally preserved at 1 year after surgery. Conclusion Surgical repair of JAA can be performed with simple cross-clamping and an acceptable renal ischemic time, achieving excellent results. Inter-renal cross-clamping reduces renal damage compared with suprarenal cross-clamping.
