Angiographic selection criteria for living related liver transplant donors.

The purpose of this study is to better define arteriographic selection criteria for living related liver transplantation (LRLT) based on literature review, technical and theoretical considerations, and correlation of patterns of variation in hepatic artery anatomy with recipient and donor outcomes.Visceral angiograms of 92 consecutive living related liver transplant donors were retrospectively reviewed by two radiologists and one transplant surgeon. Arterial configurations were categorized. Recipient and donor outcomes were determined by a review of transplant surgery and radiology records.Anomalous hepatic artery anatomy was identified in 67% of potential donors. A left hepatic artery (LHA) with a diameter of less than 2 mm was identified in 1%, and with a diameter of 2-3 mm, in 5%. A dual LHA supply to the left lateral segment was identified in 11%. Two subtypes were defined. Bifurcation of the LHA into branches entering segment II and segment III less than 1 cm from the LHA origin was present in 8%. A ...
