| Abstract: | The aim of this study is to investigate the usefulness of arterial reconstruction using the recipient''s own internal iliac artery for multiple kidney graft arteries.The safety and efficacy of various arterial reconstruction methods have been demonstrated. Although some reports have documented arterial reconstruction with the recipient''s own internal iliac artery for multiple kidney graft arteries using the interposition method, usefulness of this technique has not yet been investigated compared with other arterial reconstruction methods.Between January 2008 and April 2014, 532 living donor kidney transplants in adult recipients were performed at 1 center. Of these, 389 kidney grafts had a single artery and did not need arterial reconstruction (nonarterial reconstruction group). Among the bench surgery patients, 19 kidney grafts for multiple arteries were performed using the interposition method with the recipient''s own internal iliac artery (interposition group). Seventy-nine kidney grafts were performed using conjoined reconstruction (conjoined group) and 15 kidney grafts were performed using end-to-side reconstruction (end-to-side group). Total ischemic time (the period between arterial clamp and blood reperfusion), time to initial urination, perioperative and postoperative estimated glomerular filtration rate (eGFR), and complication rates between the interposition group and other 3 groups were retrospectively investigated. This study was based on the STROBE compliant.Warm ischemic time (the period between arterial clamp and beginning of the cold perfusion) of interposition group was significantly longer than that of nonarterial reconstruction group. Total ischemic time of the interposition group was significantly longer than those of other 3 groups. But time to initial urination, perioperative and postoperative eGFR, and complications were similar to other 3 groups.The interposition method was shown to be a useful standard method for multiple kidney graft arteries of living donor kidney transplantation in carefully selected recipients without calcification of the iliac arteries. |
