[Topography of intraabdominal supra and infra-hepatic IVC and its application in hepatectomy].

: Topographic study of infra-diaphragmatic and supra-hepatic IVC (ISIVC) was made in 16 fresh adult cadavers. The diameter and length of ISIVC averaged 35.94 +/- 5.68 mm and 16.87 +/- 5.14 mm respectively, hence making band-blockade of the ISIVC is practical. In clinical application, 21 cases of liver cancer involving the second or third hepatic hilus underwent lobectomy or segmentectomy with temporary band-blocking of the ISIVC, the infrahepatic IVC and the first hepatic hilus to prevent or to treat massive bleeding. In 3 of the 21 cases, the middle hepatic vein was inadvertently torn and was successfully suture repaired with this way.
