目的 探讨经腹切开膈中心腱阻断下腔静脉的心包内段行全肝血流阻断术的可行性。方法 在 2 5件成人经福尔马林固定的局部膈标本上解剖观测了膈中心腱前叶的形态和腱纤维的排列分层及血管分布情况。并在 1具童尸上进行模拟手术。全身动脉造影标本 1具 ,并拍片。结果 左膈下动脉前支的右支起始处的外径为 ( 0 .92± 0 .38)mm ,伴行静脉汇入左膈下静脉 ;右膈下动脉的前支的下腔静脉后支外径为 ( 0 .84± 0 .35 )mm ,其伴行静脉汇入右膈下静脉的后属支 ;右膈下动脉的前支的左支外径为 ( 0 .98± 0 .41 )mm ,伴行静脉汇入右膈下静脉的前属支。结论 经腹切开膈中心腱阻断下腔静脉的心包内段行全肝血流阻断术是可行的。
Objective To investigate the feasibility of transhepatic transposition of the central tendon to block the inferior vena cava in total pericardial blood flow occlusion. Methods Anterior segment of the anterior tendon of the diaphragm and the arrangement and distribution of the tendon fibers were dissected and observed on formalin fixed local diaphragms in 25 adults. And simulate the operation on a child’s body. Whole body arteriography 1 specimen, and filming. Results The diameter of the right branch of the left subphrenic artery at the beginning was (0.92 ± 0.38) mm, and the accompanying vein was infused into the left subphrenic vein. The anterior branch of the right subphrenic artery followed by the inferior vena cava The diameter of the branch was (0.84 ± 0.35) mm, and its accessory vein inserted into the posterior branch of the right subphrenic vein. The diameter of the left branch of the anterior branch of the right subphrenic artery was (0.98 ± 0.30) mm. 41) mm, accompanying vein into the right subphrenic anterior branch. Conclusion Transhepatic incision of the centrum tendon to block the inferior vena cava in the pericardial segment of the whole liver blood flow blocking is feasible.
