Novel Implementation of a Microvascular Coupler Device in Kidney Transplantation: Case Report

The demand for kidney transplantation remains unmet, highlighting the need to maximize the pool of potential donors. Up to one‐third of the population has accessory renal arteries, which can present challenges when used in donor grafts while maintaining adequate perfusion to the entire kidney. Various reconstruction options are technically demanding and can increase the warm ischemic time of the graft. The microvascular coupler device (MACD), commonly used in free flaps, was designed to facilitate the anastomosis of small vessels. We present the first documented successful use of the MACD in kidney transplantation, used for the anastomosis of a small accessory renal artery (ARA) to the recipient’s inferior epigastric artery.
