| Popis: | Intrahepatic portal vein occlusion has recently been postulated as a primary cause of portal hypertension (1, 10). This was based on the presence of intimal sclerosis or organized thrombi partially obstructing the intrahepatic portal radicles of patients in whom other causes of portal hypertension were excluded. Splenoportography in some of these cases has shown obliteration of the segmental or other large branches of the intrahepatic portal vein. Although occasionally similar splenoportograms may be demonstrated in schistosomiasis or cirrhosis, this abnormal intrahepatic vascular pattern was most common in the group of patients with portal hypertension, patent extrahepatic portal vein, and liver biopsies showing normal architecture with varying degrees of portal fibrosis (1). Five patients with portal hypertension of uncertain etiology have recently been studied at the Yale-New Haven Medical Center, and their radiographic and hemodynamic findings form the basis of this report. Particular attention is dir... |
