Abstract
The demonstration of a vessel in the falciform ligament, traditionally presumed to be a reopened umbilical vein, is an important sonographic sign of portal hypertension. This vessel was sought in 200 umbilicoportographies (all portal hypertensive) and in 41 autopsy-dissected falciform ligaments (34 normal and seven cirrhotic). The normal falciform ligament contained one to three tiny collapsed paraumbilical veins. In cirrhotics, the number and caliber of paraumbilical veins increased. A reopened umbilical vein was never found. The authors conclude that the umbilical vein does not recanalize in portal hypertension. The vessel involved is actually an enlarged paraumbilical vein.This publication has 10 references indexed in Scilit:
