FAQs

1

Can portal hypertension be seen on ultrasound?

Splenomegaly, ascites, and anatomy of intra- and extrahepatic portal vessels can reliably be detected by ultrasound in case of portal hypertension. The increased diameter of the portal vein and its roots is a not sufficient sensitive and specific finding in portal hypertension.
2

How does ultrasound measure portal vein pressure?

The portal venous pressure can be measured directly using either a transjugular approach to the portal vein via the hepatic veins, or by puncture of the portal vein through a percutaneous transhepatic route under ultrasound guidance. A catheter is then passed over a guidewire into the main portal vein.
3

What is sonographic appearance of portal hypertension?

Portal and splenic vein diameter greater than 10 mm, splenomegaly, hepatic and splenic hilar collaterals were suggestive of portal hypertension. Non visualization of the portal vein which was replaced by a cavernoma had a diagnostic accuracy of 98% in EHPVO.
