ABSTRACT
The article reports on determining the direction of blood flow in the veins of the anterior abdominal wall. It states that it is important to determine the direction of blood flow because it differentiates cirrhosis from vena caval obstruction. It says that the direction of blood flow in patients with dilated abdominal wall veins due to cirrhosis is away from the umbilicus, whereas in vena caval obstruction, the direction is either completely above downward or completely below upward.
