Role of Color Doppler Ultrasonography Versus Triphasic Ct With Portography in Portal Vein Thrombosis

Abstract

Back ground: Although portal vein thrombosis is a rare event among general population, its prevalence in cirrhotic patients about 28 % (1). Generally liver cirrhosis is a widespread disease, the differentiation between bland and malignant thrombus is very essential as neoplastic portal vein thrombosis gravely affects the prognosis and the subsequent treatment options (1). Doppler ultrasonography usually the first noninvasive modality used to diagnose portal vein thrombosis, using color and spectral data analysis. Triphasic CT with portography is very helpful to differentiate bland from malignant thrombus and enable characterization of malignant portal vein thrombosis using maximum intensity projection (MIP) reconstruction allow better analysis of the thrombus (2). Aim of the work: To show the role of color Doppler ultrasonography (US) and Triphasic CT in diagnosis of portal vein thrombosis (PVT) and differentiation between bland and tumoral thrombus. Patient and Methods: This study included 32 cases presented with portal vein thrombosis clinically and radiologically.
