【摘要】 目的 :为肝移植和肝部分切除术提供解剖学资料。方法 :在 40例成人尸体肝膈面沿肝左肝静脉切除肝实质 ,显露肝左静脉 ;对肝左静脉及其属支进行了观测。结果 :肝左静脉长度 ( 3 0 .3± 1 .1 )mm ;主干直径 ( 1 1 .3±0 .2 6)mm ;主要属支直径为 ( 6.0± 0 .5 2 )mm ;肝左静脉主干在膈面距离下腔静脉汇入口 1 0、2 0、3 0mm处的深度分别是 ( 1 1 .5± 0 .49)、( 1 6± 0 .5 9)和 ( 1 9.1± 0 .64)mm ;肝左静脉在膈面与肝镰状韧带呈 ( 3 0 .2 9± 1 2 .3 3 )°角 ;肝左、中静脉共干的出现率仅为 3 0 % ;肝左静脉按其属支多少分为 6型。结论 :肝左静脉在肝实质内的位置和属支数目不恒定 ,以 3～ 4支最多。所观测的资料 ,对肝外科手术具有重要意义。更多还原

【Abstract】 Objective: To provide the anatomic data for liver transplantation and the left hepatic lobotomy. Methods: The hepatic parenchyma were incised and the left hepatic veins (LHV) were exposed from the diaphragmatic surface on 40 adults cadaver liver specimens along the left hepatic veins; the principle left hepatic veins and their tributary were measured and observed. Results: The left hepatic vein were (30.3±1.1) mm in length; the terminal diameter of the principle left hepatic veins were (11.3±0.26) mm; the terminal diameter of the principle tributary were 6 mm; the depths of LHV from the diaphragmatic surface, confluence from LHV into IVC for 10 mm,20 mm,30 mm, were (11.5±0.49) mm, (16±0.59) mm, (19.1±0.64) mm, respectively; the angle between the left hepatic veins with hepatic falciform ligament were (30.29±12.33)°; the middle and left hepatic veins presented a common trunk in 30%; the left hepatic veins were divided into 6 types according to its principle tributary numbers. Conclusion: The location and the tributary numbers of left hepatic vein is various in the left hepatic lobes; the tributary number are 3-4 branches at most. These data is very important for hepatic surgery.更多还原
