We present our experience in US during the past 10 years, in 115 pediatric patients with portal vein cavernous transformation (PCT) and portal hypertension (PH). The characteristic US image makes the precise diagnosis. Umbilical vein catheterization was detected in 50.5% patients. The most common clinical findings were gastrointestinal bleeding (45.9%) and splenomegaly (24.2%). We found association with congenital diseases. The principal US signs were: splenomegaly (81%) and lesser omentum to aorta diameter ratio increased (68.7%). The others were related with collaterals: left gastric vein in lesser omentum (57.2%), Short gastric veins (42.4%), dorsal (41.5%), gallbladder varices (36.5%), ascitis (10.5%), Superior rectal veins (9.5%). The liver size was diminished in 41% and we found normal spleen in 19% patients. A patent paraumbilical vein was not observed. The PCT and PH must be diagnosed by US. We suggest that other image procedures should be used only for surgical decisions.
