Çanakkale Onsekiz Mart University kidneya transplant center results of renal artery duplication anomaly

Abstract

Purpose: The aim of this study is to retrospectively evaluate duplication anomalies of renal artery in cadaveric kidney transplants performed in our Organ Transplant Center opened in 2015 in the Bursa region. Method: Of the patients with renal artery duplication anomalies, 4 were female (7.5%), 8 were male (15%), the mean age was 55 (25–74) and the mean follow-up period was 24 months (6–42). Transplant of 11 of the patients was from the cadaver, 1 was from live donor. Artery duplication was present in all of the patients. The arteries were reconstructed with ex vivo pantaloon (side-to-side) anastomosis into a single large artery and an end-to-side anastomosis to external iliac artery was performed. Upper polar artery was ligated in a patient with a very small lower polar artery. Finding: Acute tubular necrosis developed in 3 patients postoperatively. 4 patients had lymphocele that does not require intervention and 1 patient had perirenal hematoma.Kidneys became functional in patients with ATN after an average of 3 weeks. Hematoma spontaneously resolved in the patient with perirenal hematoma. Results: The use of kidneys with renal artery duplication in transplantation involves some risks theoretically. Acute tubular necrosis, delayed graft function and rejection may be more frequent due to the prolonged cold and hot ischemic period. We think that a large single renal artery anastomosis may reduce the risk of vascular complications by ex vivo pantaloon (side-to-side) anastomosis in renal artery duplication.
