Abstract:Objective:To study the characteristics of hepatic artery anatomy and master the method of arterial repair, especially the method and technology of repair of anomalous donor arteries. Methods:Sixty-four human liver arteries were dissected and repaired, and 31 of these were used in liver transplantation. Results:Twelve of 64 cases had anatomical anomaly of hepatic artery (12/64,18.75%). Five of 24 fetal liver donors(20.83%) had anatomical anomaly of hepatic artery, one arose from the superior mesentery artery as a replaced right hepatic artery, 3 from accessory right hepatic artery, and in 1 case the hepatic artery arose from superior mesentery artery directly. Seven adults had hepatic artery anomalies:2 cases of right hepatic artery being replaced by artery derived from SMA, 2 cases of left hepatic artery deriving from left gastric artery and 3 cases of accessory right hepatic artery derived from SMA.In 31 hepatic transplantations, 4 grafts with anatomical anomaly of right hepatic artery were used. Conclusions:Reconstruction of hepatic artery plays an important role in hepatic transplantation. Avoidance of injury to aberrant hepatic avteries during removal of donor liver is a key to ensure successful arterial repair.During repair of very small accessory hepatic arteries, ligation or repair of the artery may be determined after observation of backflow from collateral vessels.
