目的：探讨门腔分流的新途径。方法：解剖观测脐静脉、静脉导管及肝圆韧带、静脉韧带等。结果：静脉导管是脐静脉的直接延续，并与下腔静脉和门静脉左支相通。静脉导管长１３１０±２５０ｍｍ。肝圆韧带连于脐和门静脉左支之间，其肝外段和肝内段长度分别为１４５１±３４４ｃｍ，５７５±０９９ｃｍ；静脉韧带走行于肝下面的静脉韧带裂内，连于门静脉左支和下腔静脉之间，长约４０９±０６１ｃｍ。静脉韧带和肝圆韧带内均有间断残腔存在，且以近心段最为明显，分别长达１９９±１３９ｃｍ和２９１±０６２ｃｍ。肝圆韧带和静脉韧带均可用直径２ｍｍ的铁丝使其再通。结论：于脐处切口，扩张并再通肝圆韧带、静脉韧带至下腔静脉，实现门腔分流，具有解剖学形态基础。
Objective: To explore a new way of shunting portal cavity. Methods: Anatomical observation of umbilical vein, intravenous catheter and liver round ligament, ligaments and so on. Results: The venous catheter is a direct continuation of the umbilical vein and communicates with the left branch of the IVC and the portal vein. Intravenous catheter length 13 10 ± 2 50mm. The ligament of the liver was ligated between the umbilicus and the left branch of the portal vein. The lengths of the extrahepatic and intrahepatic segments were 14.51 ± 3.44cm and 575 ± 0.99cm, respectively. Within, even between the left branch of the portal vein and inferior vena cava, about 4 09 ± 0 61cm. There were intermittent residual cavity in the vein ligament and the round ligament of liver, and the most obvious in the proximal segment was 199 ± 139cm and 291 ± 062cm, respectively. Liver round ligament and vein ligaments are available 2mm diameter wire to recanalization. Conclusion: Incision at the umbilicus, expansion and recanalization of the hepatic ligament and venous ligament to the inferior vena cava, to achieve portal shunt, with anatomical basis.
