Abstract

Objective Discussion on classification and diagnostic value of multi-slice spiral CT portography (CTPV) on portal hypertension (PHT). Methods A total of 42 patients with PHT, 26 cases of intrahepatic PHT, both in patients with liver cirrhosis, and hepatocellular carcinoma in 7 cases,3 cases of intrahepatic portal vein tumor thrombosis; before the liver of PHT13patients, including 3 cases of portal vein thro mbosis in 4 cases of outer segment, portal vein tumor thrombus in 6 cases of outer segment,cavernous transformation, liver after PHT Budd Chiari syndrome in 3 cases; underwent imaging of 64 slice spiral CT portal, MIP, VR,MPR or CPR reconstruction using volume data, observation of portal vein branches, collateral circulation, characteristics of imaging. Results CTPV can clearly show the initial distribution, evaluating collateral circulation of portal hypertension degree and position classification. Conclusion CTPV can accurately diagnose PHT and differential classification, have important significance to establish prediction of its complications, operation scheme.

Introduction

根据门静脉血流阻力的产生部位结合显微结构,门静脉高压症(portal hypertension,PHT)分为肝前性、肝内性、肝后性[1]，了解其发病部位分类对于内科治疗或外科手术方案的选择具有重要意义。多层螺旋CT门静脉成像(computed tomography portal venography,CTPV)是目前临床上广泛应用的无创性评价门体分流的重要方法之一[2-3]。本研究旨在探讨CTPV对PHT的诊断及部位分类价值。
