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.
