    Abstract:
    The purpose of this study is to identify the existence of hepatovenous intrahepatic anastomosis in normal men. A total of thirteen livers were investigated during the early autopsies of normal men who died in accidents. Perfusion venography of branches of hepatic veins using meglucamine diatrizoate was done in six cases; this method we used had not been reported in the literature. In one case, portal venography was performed. And in the other six cases, liver substance staining was done by injecting the ink through the middle hepatic vein, and such staining of the liver was observed by light microscope. The results show, (1) there are intrahepatic anastomoses between the hepatic veins within the liver; (2) there are anastomoses between the middle hepatic vein and the accessory hepatic veins; and (3) shunts exist between portal veins and hepatic veins. The above findings provide an anatomical basis for the performance of irregular hepatectomy and the rationale for one or two hepatic veins ligation should such veins were traumatized or invaded by liver cancer.
