下腔静脉口

方法：用游标卡尺测量101例成人尸体的下腔静脉口和肝静脉入口之间的距离。

Methods : The distance between the orifice of inferior vena cava and that of hepatic vein was measured with vernier calliper in 101 adult cadavers .

结果：下腔静脉口和最高一条肝静脉入口上缘的间距为20.3±5.2mm；

Results : The distance between the orifice of inferior vena cava and the superior margin of the orifice of the highest hepatic vein was 20.3 ± 5.2 mm ;

下腔静脉口和最低一条肝静脉入口下缘的间距为40.7±7.2mm。

And its distance to the inferior margin of the orifice of the lowest hepatic vein was 40.7 ± 7.2 mm .

方法选用成年杂交犬10条。根据下腔静脉吻合口的位置不同分为两组：1组为下腔静脉与右肺动脉吻合；

Methods Ten adult mongrel dogs were divided into two groups according to the anastomosis site of inferior vena cave ( IVC ): group I , IVC anastomosed to right pulmonary artery ;

余4只术后存活未能超过7日，其中1例由于麻醉意外死亡，1例死于肠梗阻，2例死于肝上下腔静脉吻合口出血。

The rest of 4 cases failure to survive more than 7 days : 1 case died of anesthesia accidents , 1 case died of intestinal obstruction , 2 cases died of the suprahepatic inferior vena cava anastomotic bleeding .
