V2161: Robotic Renal Artery Aneurysm Repair with Intra-arterial Renal Hypothermic Perfusion
VideoIntroduction and Objectives
Complex renal artery aneurysm involving multiple branch vessels is a challenging scenario. The use of renal cold perfusion is recommended when warm ischemia times are expected to exceed 30 minutes. We present a case of robot-assisted laparoscopic repair of a complex renal artery aneurysm with the use of intra-arterial hypothermic kidney perfusion.
A 49 year old female with left flank pain and hypertension was found to have a complex renal artery aneurysm. She underwent a robotic renal artery aneurysm repair with intra-arterial renal hypothermic perfusion.
Warm ischemia time was 29 minutes for the first aneurysm repair. The kidney was then re-perfused for 60 minutes followed by re-clamping and repair of the second aneurysm with a warm ischemia time of 26 minutes. Total operative time was 210 minutes .The patient was discharged on postoperative day 2. A follow-up at 4 months demonstrated stable renal function with resolution of her flank pain and normalization of the blood pressure.
Robotic repair of complex renal arterial aneurysm with intra-arterial cooling is feasible and a safe option when prolonged renal ischemia is expected.
