[Transvenous perfusion, a new simple and effective technique of regional renal hypothermia. An experimental study...

In an experimental study, involving ten dogs, the feasibility of transvenous perfusion cooling of the kidney is proven. The theoretical basis of this new method of regional renal hypothermia is presented. The technique is easy to perform and requires cannulation of the renal vein. The perfusate leaves the kidney either via the capsular veins which were divided during renal exposure or through the proposed nephrotomy. Renal vein thrombosis or venous disruption have not been observed. The only complication encountered in one instance was hemorrhage from the puncture site of the renal vein.
