  • A MODIFIED ARTERIAL SLEEVE ANASTOMOSIS IN RAT RENAL TRANSPLANTATION

    Objective To improve arterial anastomosis method for rat renal transplantation. Methods Renal transplantations were performed on 72 wistar rats. The donor superior mesenteric artery was end-to-end anastomosed to the recipient left renal artery by using of sleeve anastomosis technique. The external diameters of the vessels anastomosed were 0.60±0.05 mm (left renal artery) or 0.80±0.07 mm (superior mesenteric artery). The procedure consisted of a guidingsuture and two fixing sutures. The guiding suture was used to “telescope” therecipient left renal artery into the donor superior mesenteric artery about 2 millimetre. Two fixing sutures were applied 180°apart from each other and tied. Three sutures passed through all layers of the donor superior mesenteric artery andconstricted the vessel lumen, but only penetrated the adventitia of the recipient left renal artery. Results The time for arterial anastomoses was approximately 6 to 8 minutes. The renal grafts perfused very well after the recipient left renal artery clamp was removed. Complications included anastomotic hemorrhage(1 case) and thrombosis (1 case). Histologic examination of 34 grafts at different postoperative time ranging from 6 to 30 days revealed that renal artery was fully patent, with no evidence of ischemic injury. Conclusion The modified arterial sleeve anastomosis technique is simple and feasible regardless of experimentalcondition and can be easily performed.
