【摘要】： 目的:了解肝中静脉(middle hepatic vein MHV)及主要属支解剖,为肝切除术和肝移植术中肝中静脉主干保留与否,是否重建MHV属支提供解剖基础。方法:收集32例人体肝脏标本,解剖MHV及其大于5mm属支,观测大于5mmMHV属支的数目以及在各肝段分布情况。结果:32例标本中,18例MHV和LHV共干回流下腔静脉(inferior vena cava IVC),占56.3%;14例各自回流IVC,占43.7%。在肝IV段内,大于5mm属支1支的19例(59.4%),2支的有6例(18.8%),3支的1例(3.1%),3支以上的1例(3.1%)。在肝V段内,大于5mm属支1支的2例(6.2%),有2支的13例(40.6%),有3支的11例(34.4%),3支以上的6例(18.8%)。在肝VIII段内,大于5mm属支1支的有11例(34.4%),2支的16例( 50%),3支的3例(9.4%),3支以上的2例(6.2%)。结论:本课题为扩大的左右半肝切除、中肝切除、劈离式肝移植(split liver transplantation, SLT),减体肝移植(reduce-size liver transplantation RLT)和活体肝移植(living donor liver transplantation LDLT )中肝中静脉主干及主要属支去留、重建与否提供了解剖学基础。
[Abstract]:Objective: to investigate the middle hepatic vein MHV) and main branch anatomy of middle hepatic vein in order to provide anatomical basis for the preservation of middle hepatic vein trunk during hepatectomy and liver transplantation and the reconstruction of MHV branch. Methods: 32 samples of human liver were collected, MHV and its branches larger than 5mm were dissected, the number of branches larger than 5mmMHV and its distribution in each segment of liver were observed. Results among 32 specimens, 18 cases (56.3%) were refluxed from the common trunk of MHV and LHV to inferior vena cava IVC, accounting for 43.7% (14 / 32). In the IV segment of the liver, 19 cases (59.4%) with a branch larger than one branch of 5mm were involved in 6 cases with 18. 8 or 3 branches and 1 case with 3 or more branches of 5mm. In the V segment of the liver, two patients with greater than one branch of 5mm were involved, 13 patients with 2 branches were involved in 40.6 and 11 patients with 3 branches had 3 branches or more than 3 branches. In the VIII segment of the liver, there were 11 cases with greater than one branch of 5mm and 16 cases with 2 branches of 5mm. Conclusion: the main trunk of the middle hepatic vein and its main branches in the left and right hemihepatectomy, middle hepatectomy, split liver transplanation, subtractive liver transplantation, reduce-size liver transplantation RLT) and living donor liver transplantation LDLT) were studied. Reconstruction or not provides an anatomical basis.
