Experiences of rescuing infective arterial hemorrhage and pseudoaneurysm in DCD kidney transplantation

Abstract

Objective: To summarize experiences of rescuing arterial hemorrhage and pseudoaneurysm caused by infection in donation after cardiac death (DCD) kidney transplantation. Methods: A total of 198 consecutive DCD kidney transplantations between 1 June 2013 and 30 July 2016 in the Third Affiliated Hospital of Sun Yat-sen University were retrospectively analyzed. The means of rescuing infective arterial hemorrhage and pseudoaneurysm after operation and their therapeutic effects were summarized. Results: A total of 5 infective arterial hemorrhage, 2 infective pseudoaneurysm with hemorrhage, and 1 infective pseudoaneurysm developed in 198 DCD kidney transplantation recipients with total morbidity of 4.0%, and the morbidity of fungal infection accounted for 2.5%. One case received open surgical therapy. Two cases were treated with endovascular interventional therapy. Five cases received combined treatments of open surgery and endovascular intervention. Selective antibiotics were used based on drug sensitivity test postoperation. The wound was drained, and the drainage was repeatedly cultured to monitor the pathogen till the results turned to negative. Five patients received graft nephrectomy and were restored to hemodialysis. Two patients were successfully rescued with stable graft function. One case died. The mortality of patient was 1/8. Graft loss rate was 5/8. Both patients with stable graft function were mainly treated by intervention. Conclusions: Infective arterial hemorrhage and pseudoaneurysm were primary risk factors causing patient/graft death postoperation in DCD kidney transplantation. Endovascular therapy can be used as an effective rescuing method under the circumstance of infection. The measure allows opportunity of successfully rescuing kidney graft and deserves recommendation.
