Clinical characteristics of idiopathic portal hypertension

Figure 1 Our proposed theory about etiopathogenesis of idiopathic portal hypertension.

Figure 2 The histological examination of the portal vein shows periportal thickening (marked by asterisks) found in an IPH patient.

Figure 3 Splenopo-rtography shows two major sites of thrombosis in portal venous system (shown by asterisks). Note the dilated portal vein at hepatic hilum despite portal vein thrombosis.

Figure 4 The computed tomography of the same patient in figure-3. Note the thrombosis in the portal vein (Marked by arrow).

Figure 5 Splenoportography shows patent portal vein with severe dilation and collateral circulation. Note the small caliber of intrahepatic portal vein branches compared to extrahepatic portal vein.
