In sixty normal adult livers the retrohepatic segment of the inferior vena cava was found mostly to assume a curve to the left (75.00%). This segment has a length of 7.1 cm and is totally encircled by liver substance in 6.67% of cases. Altogether 492 ostia venae hepaticae were studied, averaging 8.2 per liver and classified as large, medium and small. The large ostia are divided into superior (SLO) and inferior (ILO) openings. The SLO are found opening into the upper end of the hepatic segment of the inferior vena cava, frequently with part of the venous walls exposed outside the liver. The ILO and medium ostia are present in 95% of the livers, appearing mainly on the lower quarter of the right half of the wall of the retrohepatic segment of the inferior vena cava as well as on the left anterior wall of that segment. The ILO may serve as the exit for several hepatic veins and they may be multiple. Their significance in respect of liver surgery is discussed.
在60个正常成人肝脏中，发现下腔静脉肝后段大多向左弯曲（75.00%）。该段长度为7.1厘米，在6.67%的病例中完全被肝实质包围。共研究了492个肝静脉口，平均每个肝脏8.2个，并分为大、中、小三类。大的肝静脉口分为上开口（SLO）和下开口（ILO）。发现SLO开口于下腔静脉肝段的上端，静脉壁的一部分常暴露于肝外。ILO和中等大小的肝静脉口存在于95%的肝脏中，主要出现在下腔静脉肝后段右半壁的下四分之一以及该段的左前壁。ILO可能是几条肝静脉的出口，且可能不止一个。文中讨论了它们在肝脏手术中的意义。
