 note = {Percutaneous transhepatic portography (PTP), estimation of spleen and liver volume by CT and measurement of portal system blood flow volume by ultrasonic Doppler duplex system were carried out in 32 patients with chronic liver disease (LC : 21, PBC : 5, IPH : 4, others : 2). Collateral pathways visualized by PTP in those patients were classified to 4 patterns : Gastro-Esophageal (type 1), Gastro, Spleno-Renal (type 2), Paraumbilical reflux (type 3) and others (type 4). Type 1 collateral pathway was most frequently observed (71% of all cases), and all of 5 PBC patients revealed to show this pattern of collateral pathway, In LC patients, correlation exsisted between portal vein pressure and total collateral area (TCA) (p<0.05), and LC patients with type 2 collateral pathway showed large TCA and low portal vein pressure. Portal vein pressure in LC patients increased in relation to the increase of spleen volume and the decrease of liver volume (p<0.01). Outflow blood volume of the splenic vein and inflow blood volume of the portal vein increased significantly in IPH patients compared to LC or PBC (p<0.01). LC patients who revealed encephalopathy possessed type 1 or type 2 collateral pathway, and decrease of Fischer ratio in type 1, increase of serum ammonia level in type 2 was considered to be a triggering factor to develop an encephalopathy.},
