Portosystemic collaterals

Authors

Abstract


This article aims to describe the various portosystemic collateral pathways in patients with portal hypertension on multidetector row computed tomography and their clinical importance, with special emphasis on the uncommon collaterals. This will have important implications both for the clinician and the radiologist. Multidetector row computed tomography with its advanced postprocessing abilities can demonstrate these collaterals to help in therapeutic decision making.
