The author has studied the main hepatic artery (HA) alterations and liver related disease (LRD) in 80 donors. The normal arterial anatomy with a single HA arising from the celiac trunk was seen in 61% of cases; a left hepatic artery (LHA) off left gastric artery (LGA) in 19% of cases and a right hepatic artery (RHA) arising from superior mesenteric artery (SMA) in 15% of cases. Two rare anomalies: an HA off anastomosis connecting celiac trunk to SMA and a LHA off LGA around the esophagus. A case of absence of celiac artery and the splenic artery (SA) was found arising directly from the aorta, and another one the SM arose from RHA. Six livers were turned down: 3 by cholecystitis, 2 by preoperative hypoxia and 1 by hepatic polycystic disease. Steatosis and hemangioma have been among the others LRD. In conclusion, HA and LRD have occurred in approximately 50% of donors, this fact underline the importance of searching the anomalies of the HA and LRD during the organ retrieval.
作者研究了80例供体的肝动脉（HA）主要变异情况及肝脏相关疾病（LRD）。61%的病例可见正常动脉解剖结构，即肝动脉由腹腔干单一发出；19%的病例肝左动脉（LHA）发自胃左动脉（LGA）；15%的病例肝右动脉（RHA）发自肠系膜上动脉（SMA）。有两种罕见变异：一种是肝动脉发自连接腹腔干与肠系膜上动脉的吻合处，另一种是肝左动脉在食管周围发自胃左动脉。发现1例无腹腔动脉，脾动脉（SA）直接发自主动脉，另1例肠系膜上动脉发自肝右动脉。6个肝脏被弃用：3个因胆囊炎，2个因术前缺氧，1个因肝多囊病。脂肪变性和血管瘤也属于肝脏相关疾病。总之，约50%的供体出现肝动脉变异及肝脏相关疾病，这一事实凸显了在器官获取过程中探查肝动脉变异及肝脏相关疾病的重要性。
