Aim. The aim of this study was to investigate the incidence of anatomic variations of hepatic artery (HA) in order to evaluate if anatomical anomalies may be associated with an increased incidence of hepatic artery thrombo – sis (HAT) after orthotopic liver transplantation (OLT). Moreover, we focused on arterial reconstructive technique associated with a low incidence of HAT. Methods. We reported a consecutive series of 687 OLT in 601 patients (1986-1999). Hepatic arterial reconstruction was variable and dependent upon donor and recipient anatomy, even if arterial anastomosis was mainly of two types: the end-to-end anastomosis (EEA), used in 340/687 OLT (49.4%) and the branch patch anastomosis (BPA), performed in 347/687 OLT (50.5%). Interrupted sutures of 7/0 polypropylene always were used.
