Splenoportography has been proved as a useful method for the evaluation of circulatory disturbances in portal hypertension. Authors analyzed the various aspects of these disturbances on splenoportography in 22 cases that were performed under the clinical suspicion of portal hypertension during recent 6 years, from May, 1976 to July, 1982 at the Department of Radiology, National Medical Center. The results were as follows : 1. Liver cirrhosis was the most frequent cause of intrahepatic obstruction type in portal hypertension (86%). 2. The portal pressure was more than 400mm H2O in 67% of the cases (range ; 300-540mmH2O). 3. In the majority of the cases, the higher the portal pressure was, the more dilated splenic and portal veins were. The diameter of portal vein was more than 15mm in 79%, more than 21mm in 47% of the cases (range ; 10-26mm). The diameter of splenic vein was larger than that of protal vein in 20% of the cases. 4. There was no definite correlation between the development of collateral circulation and diameter of splenic and portal veins. 5. The filling of collateral circulation was definite sign of portal hypertension, though not regular. In portal hypertension, the collateral circulation was formed via coronary vein (91%), short gastric vein (64%), inferior mesenteric vein (36%). 6. Splenic-hilum time was delayed in 64% of the cases. Intrahepatic portal vein emptying time was more than 6 seconds in all the cases. 7. Most of the cases (91%) could be diagnosed as portal hypertension with vasculogram an d hepatogram.
