    Abstract:
    Free and wedged hepatic venography were carried out in 37 patients with idiopathic portal hypertension (IPH) and the findings compared with those in 88 patients with cirrhosis of the liver. Characteristic changes in IPH included frequent vein-to-vein anastomoses, narrower angles between large veins and their tributaries, smooth and wavy middle-sized to large branches (giving a general "weeping willow" appearance), homogeneous sinusoidal filling, and minimal to absent filling of the portal venous system on wedged retrograde portography. In cirrhosis, by contrast, changes included rare vein-to-vein anastomoses, wide angles between veins and tributaries, irregular stenoses of large veins and branches at various levels, spotty sinusoidal filling, and frequent retrograde flow in the portal venous system. Hepatic venography is helpful in differentiating IPH from cirrhosis.
