摘　　要：目的：探讨肝迷走供血动脉规律及其对外科手术和肝肿瘤介入治疗的意义。材料与方法：200例成人行中上腹螺旋CT双期扫描，观察肝脏供血动脉的起源及走行，并将不同类型肝迷走动脉加以统计分析。结果：200例成人中31例出现迷走血管。肝左、肝右动脉起自腹腔干9例；肝总动脉起自肠系膜上动脉6例；迷走肝右动脉起自肠系膜上动脉4例；迷走肝左动脉起自胃左动脉4例，肠系膜上动脉2例，胃右动脉1例；腹主动脉发出副肝左、副肝右动脉2例。结论：非侵入性螺旋CT双期扫描能够显示肝脏迷走供血动脉，为外科手术和肝动脉插管介入治疗提供重要的影像学依据。Objective: To study the rule of the anomalous hepatic blood supply and to evaluate it in surgical and interventional treatrment for hepatic tumors. Materials and Methods: Routine biphasic helical CT scan Of upper abdomen was performed in 200 patients. The location and Origin Ofall aberrant hepatic artenries were Observed, classified and analyzed. Results: Aberrant left or right hepatic arteries originated from celiac artery wereidentified in 9 patients, aberrant common hepatic artery from SMA in 6, aberrant right hepatic artery from SMA in 4, and aberrant left hepatic arteryfrom left gastric, SMA or right gastric artery in 4, 2 and 1, respectively. Conclusion: Non-invasive biphasic helica1 CT scan can demonstrate aberrant hepatic arteries, providing surgical or interventional management with important imaging information.
