Abstract
Background:Altered portal hemodynamics and inflammation may occur following transcatheter arterial chemoembolization (TACE), but early biological and portal perfusion changes are not well characterized when this procedure is performed selectively.Material/Methods:We studied variations in portal flow velocity (PFV) using Doppler ultrasonography, as well as serum TNFa, vCAM-1, and E-Selectin at 2 and 24 hours after supraselective TACE in 15 consecutive patients with cirrhosis and hepatocellular carcinoma.Results:Variations in PFV occurred both in the embolized and non-embolized liver lobe. PFV increased significantly at 2 hours in the right and left portal vein. At 24 hours, right PFV remained elevated. Serum TNFa increased significantly at 2 hours, but VCAM-1 and E-Selectin levels remained unchanged. Changes in right and left PFV showed a positive correlation (r=0.9, p
