We evaluated sequential computed tomography (CT) arterioportography-arteriosplenography for the assessment of venous pathways in children with portal hypertension without cirrhosis. Institutional Review Board approval was obtained for this retrospective, single-centre study. CT was performed after contrast application via catheters placed in the superior mesenteric artery (CT arterioportography) and the splenic artery (CT arteriosplenography) consecutively. Venous pathways in 22 children were evaluated. In all patients, the detailed haemodynamic consequences of portal hypertension could be characterised. The supply of varices at different locations could be assigned to the superior mesenteric vein or splenic vein system. Retrograde blood flow through the splenic vein and inferior mesenteric vein, portosystemic shunting, and patency of splanchnic veins were determined. CT arterioportography-arteriosplenography allowed a complete evaluation of individual haemodynamic pathways in children with portal hypertension.
我们评估了序贯计算机断层扫描（CT）动脉门静脉造影-动脉脾门静脉造影，以评估无肝硬化的门静脉高压患儿的静脉通路。本回顾性单中心研究获得了机构审查委员会的批准。通过依次置于肠系膜上动脉（CT动脉门静脉造影）和脾动脉（CT动脉脾门静脉造影）的导管注入造影剂后进行CT检查。评估了22例患儿的静脉通路。在所有患者中，均可明确门静脉高压的详细血流动力学后果。不同部位静脉曲张的供血可归因于肠系膜上静脉或脾静脉系统。确定了通过脾静脉和肠系膜下静脉的逆流、门体分流以及内脏静脉的通畅情况。CT动脉门静脉造影-动脉脾门静脉造影能够全面评估门静脉高压患儿的个体血流动力学通路。
