title: [Doppler ultrasound in portal hypertension: qualitative analysis].
abstract: Duplex Doppler US is a procedure that enables confirmation--and in many instances--detection of portal hypertension by visualizing the presence of collateral blood vessels and determining the direction of the portal flow. In addition, absence of Doppler signal into the veins allows assessment of venous thrombosis both in the portal and hepatic veins.
