目的:观测肝左静脉的解剖结构,为活体肝移植供肝切取和供肝肝左静脉与受体静脉吻合提供解剖学基础。方法:通过50例成人无病变肝脏剥离解剖,对肝左静脉进行形态学观测,采集相关数据并进行统计分析。结果:肝左静脉(LHV)与肝中静脉(MHV)共干和非共干者分别为80.00%(40/50)和20.00%(10/50);共干血管长度及其近端直径是(5.09±2.78)mm和(12.02±1.91)mm,非共干LHV与MHV开口间距离为(2.00±1.15)mm;LHV肝外段长度为(9.89±4.86)mm;LHV主干(96.00%,48/50)居镰状韧带左侧,成(35.31±16.79)°角;LHV主干长度及其近端直径为(39.1±15.16)mm、(8.44±1.28)mm;LHV的引流段变化较大,依据属支的多少可分5型。结论:LHV多与MHV共干注入IVC,LHV肝外段和外科干长度以及LHV的投影个体差异甚大,活体肝移植前掌握供肝LHV主干及其属支的解剖,有助于设计合理的手术方案。
OBJECTIVE: To observe the anatomy of the left hepatic vein and provide an anatomical basis for anastomosis of donor liver graft and donor hepatic left venous vein with donor vein. Methods: The morphology of the left hepatic vein was observed by collecting 50 cases of non-diseased liver dissection and the related data were collected and analyzed statistically. Results: The total dry and non-co-transfected hepatic vein (LHV) and non-hepatic vein (MHV) were 80.00% (40/50) and 20.00% (10/50), respectively. (5.09 ± 2.78) mm and (12.02 ± 1.91) mm, respectively. The distance between the LHV and MHV openings was (2.00 ± 1.15) mm and the length of extrahepatic segment of LHV was (9.89 ± 4.86) mm. The LHV trunk (96.00% (35.31 ± 16.79 °). The length of the trunk of the LHV and the diameter of the proximal end of the trunk were (39.1 ± 15.16) mm and (8.44 ± 1.28) mm, respectively. The drainage segment of LHV varied greatly , According to the number of branches can be divided into 5 types. Conclusions: There are great differences between LHV and MHV co-injected into IVC. The LHV extrahepatic segments and surgical stem length as well as LHV projection individuals are very different. To master the anatomy of donor liver LHV and its branches prior to living donor liver transplantation is helpful to design reasonable operation Program.
