The diagnostic value and limitation of "systemic hapatic angiographies" to evaluate the resectability of infantile hepatic tumors was studied. Eleven cases undergone hepatic angiograms for hepatic tumor were discussed and following conclusions were made. 1) The diagnostic rate of hepatic arteriogram, portogram and hepatic venogram was 54.5%, 100%, 50% respectively. 2) The main reasons of diagnostic failure were the following factors : 1. Difficulties in identification of feeding artery due to involvement of the arteries in the tumor vessels. 2. Poor visualization of the left portal branch. 3. Technical difficulties of middle hepatic vanography. 3) All cases except one could be diagnosed correctly, by comprehensive judgement using arteriogram, portogram, cavogram and venogram. One failure case was due to poor visualization. These results indicate that systemic hepatic angiographies are usuful to predict localization and extension of infantile hepatic tumors. Preoperative systemic hepatic angiographies are also needed in infants for safe and effective hepatic resection.
