【摘要】 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。更多还原

【Abstract】 Objective To find out the possibility of omni-liver blood stream interruption blocking the inferior vena caval pericardium inter-portion by incisioning diaphragma central tendon through the abdomen. Methods The form, arrangement delamination of tendon fiber, distributions and diameters of the arteries in the anterior lobe of diaphragma central tendon were investigated on 25 adult fixed local diaphragm injected with ink. Modeling operation were performed on a child fresh cadaver . Lead oxide-gelatin suspension as developer was used and photo was taken on an adult cadaver to display its arteries. Results The right branch arisen from the anterior branch of the left phrenic is 0.92±0.38 mm at its initiation, its accompanying vein to from the left phrenic veins. The inferior vena vava posterior branch arisen from the anterior branch of right inferior phrenic is 0.84±0.35 mm, its accompanying vein to from the posterior branch of right phrenic veins. The left branch arisen from the anterior branch of right inferior phrenic is 0.98±0.41 mm, its accompanying vein to from the anterior branch of right phrenic veins. Conclusion It is possible to block the inferior vena caval pericardium inter-portion by incisioning diaphragma central tendon through the abdomen.更多还原
