Hepatic venographies were performed selectively in 42 patients with hepatocarcinoma. The findings were evaluated from anterior and lateral views. Thirty-nine right hepatic v. could be identified and the existence of one branch as the first ramification was found in 36 cases (92.3%). The first branches of the right hepatic v. could be classified into veins (V7) running from segment VII and those (V8) running from segment VIII. A V7 was identified in 26 cases (72.8%) and a V8 was identified in 10 cases (27.8%). The vena hepatica dorsalis (V8) running from segment VIII was recognised in 10 cases. The middle and left hepatic v. were identified in 31 cases and 33 cases respectively. Two main types of middle vein (one with no principal branching and the other with branching) were found in 11 cases (37.9%) and 12 cases (41.4%) respectively. The first branch of the middle hepatic v. (V8) running from segment VIII was identified in 10 cases (32.3%). These results indicate that anatomical consideration of the hepatic v. in each patient is necessary when performing hepatic resection.
对42例肝癌患者进行了选择性肝静脉造影。从前后位和侧位观察结果。可以识别出39支右肝静脉，36例（92.3%）发现存在一支作为第一分支。右肝静脉的第一分支可分为起自Ⅶ段的静脉（V7）和起自Ⅷ段的静脉（V8）。26例（72.8%）识别出V7，10例（27.8%）识别出V8。10例识别出起自Ⅷ段的肝背静脉（V8）。分别在31例和33例中识别出肝中静脉和肝左静脉。11例（37.9%）和12例（41.4%）分别发现两种主要类型的肝中静脉（一种无主要分支，另一种有分支）。10例（32.3%）识别出起自Ⅷ段的肝中静脉第一分支（V8）。这些结果表明，进行肝切除时，有必要对每位患者的肝静脉进行解剖学考量。
