title: [Clinical significance of selective middle hepatic venography].
abstract: Selective middle hepatic venography was performed in 86 patients who had been scheduled to undergo liver resection because of hepatobiliary diseases. Special catheters were used of which tips were bended counterclockwise at an angle of 45 degrees. Successful middle hepatic venograms were obtained in 65 cases (76%). Abnormal findings were observed in 27 cases (42%), and it was difficult to diagnose them by ultrasonography or computed tomography. Selective middle hepatic venogram is very useful to understand surgical anatomy of the liver in each case preoperatively. In 5 cases of giant tumor, middle hepatic venography is necessary to identify the exact site of the tumor. Selective middle hepatic venography is considered to be one of the indispensable, examinations for liver resection.
