在肝圆韧带形态研究基础上，利用探针扩张和流体静压灌注两种方式对２１例新鲜成人标本进行离休再通，探讨该两种方式对肝圆韧带的形态影响及再通过程中的力学特性。结果表明：探针扩张可使肝圆韧带及脐一门静脉连接处再通，进入门静脉左干囊部。肝圆韧带最大可扩张内径为３．５～５．５ｍｍ。扩张再通常致肝圆韧带内膜脱落或穿破内膜层形成人工假道。流体静压灌注可避免人工假道产生且使肝圆韧带再通，对脐一门静脉连接处常需加用探针辅助，才能使肝圆韧带全程再通。在流体静压灌注过程中，肝圆韧带压力与再通长度变化关系呈“Ｓ”形曲线，再通压力范围为７．９８～１３．３ｋＰａ；压力与管径变化关系显示，游离段在７．９８～１８．６２ｋＰａ压力范围内管径扩张最为显著，裂隙段管径随灌注压力增加而增大。流体静压灌注对肝圆韧带管壁损伤较小。研究结果揭示流体静压灌注及探针辅助肝圆韧带人工再通方式具有临床推广应用价值。
Based on the study of the morphology of the hepatic ligament, 21 fresh adult specimens were reexamined by probe dilation and hydrostatic perfusion. The morphological changes of the ligamentum flavum Mechanical properties. The results show that: the expansion of the probe can make the round ligament of the liver and umbilical a portal vein recanalization, into the left portal vein dry Department. Liver round ligament maximum expandable diameter of 3.5 ~ 5.5mm. Expansion and then usually lead to the liver round ligament or endometrial shedding the formation of artificial iliac arteries. Hydrostatic perfusion can prevent artificial seizure and the recanalization of the liver round ligament, umbilical a portal vein often need to add probe-assisted, in order to round the liver round the whole recanalization. During hydrostatic perfusion, the relationship between the pressure on the round ligament and the recanalization length showed a “S” shaped curve with the recanalization pressure ranging from 7.98 to 13.3 kPa. The relationship between pressure and tube diameter showed that the free segment was at 7 In the pressure range of 98 ~ 18.62kPa, the diameter expansion is the most significant, and the diameter of the fracture section increases with the increase of perfusion pressure. Hydrostatic perfusion of liver round ligament wall damage less. The results revealed that fluid hydrostatic perfusion and probe-assisted circular ligament artificial recanalization method has clinical application value.
