Portal Venous Hypertension

1. Pathogenesis:

• Commonly found in patients with cirrhosis.

2. Radiographic findings:

• U/S, CT, MRI: may show ascites, splenomegaly, and portosystemic varices. Most commonly identified varices are the paraumbilical vein, splenorenal, and/or gastrorenal veins.
   
• Doppler U/S: may be used to determine if flow is hepatofugal (away from the liver) or hepatopedal (toward the liver).
