Spontaneous and arteficial portosystemic shunts detected by three-dimensional ultrasonography

Introduction: Portal hypertension has different causes that can be detected by different ultrasonographic methods such as color Doppler and duplex sonography. Ultrasonography can distinguish the different types of liver diseases by measuring the portal vein diameter, the velocity of the portal flow and by detecting the collaterals and the status of the liver. Aim of the study: In portal hypertension the spontaneuosly recanalized or hypertrophied vessels can form a direct or indirect connection between the portal vein and vena cava or the vessels. There is a high degree of variability. The different types of shun…
