Effects of Hepatic Artery Type And Number on Bile Complications in Right Lobe Living Donor Liver Transplant Recipients: Single Center Experience Without Hepatic Artery Thrombosis

Purpose: Hepatic artery provides blood supply to the biliary tract of the graft, one of the causes of the biliary complications that may occur in the post-transplant period may be the problems of the recipient's hepatic artery. We examined the effect of post-transplant biliary complications according to the type and number of recipient hepatic artery. Materials and Methods: One hundred eighty five patients older than 18 years of age who underwent right lobe LDLT for end-stage liver cirrhosis were included in the study. The recipient's right hepatic artery (RHA), left hepatic artery (LHA), propria hepatic artery (PHA) and common hepatic artery (CHA), which were anastomosed to the graft artery and double hepatic artery anastomoses formed of the right and left hepatic arteries, were examined. Biliary complications were analyzed statistically in terms of single or double artery anastomosis and anastomoses with the right or the other hepatic arteries. Results: There was no statistically significant difference between single and dual artery anastomoses in terms of bile duct stricture or leakage (p=0.767). No statistically significant difference was observed between RHA, LHA, PHA, CHA, and between single and dual arteries in the evaluation of artery selection between those with and without biliary tract complications (p=0.445) Conclusion: Hepatic artery type selection and number of the recipient does not change the biliary tract complication.
