Title: Hepatofugal Collaterals in Advanced Liver Cirrhosis: Identification with CT Portography
Abstract: Portal hypertension is a common syndrome that is characterized by pathologic increase in portal venous pressure and by the formation of portal systemic collaterals that shunt part of portal venous blood to the systemic circulation. Knowledge of hemodynamic circulation and portal venous collateral pathways is important for clinical physicians. Multi-detector row computed tomography (CT) offers important advantages over conventional imaging methods in the evaluation of the portal venous vasculature because of faster scanning and thinner collimation. These advances allow excellent visualization of the portal veins and hepatofugal collateral channels. Three-dimensional CT portography may also have technical potential to generate excellent image for volumetric reconstructions and hemodynamic evaluation of the portal vein and its collaterals. From January to December 2004, 148 patients with liver cirrhosis were enrolled for this study and hepatofugal collaterals were identified in 112 patients. Three-dimensional CT portography provided comprehensive mapping of vascular compromise and collateral formation and therefore, improved medical treatment quality.
