The objective of this article is to illustrate the imaging features of patients with extrahepatic portal venous obstruction who are evaluated before or after a Rex shunt surgery.
The Rex shunt is a potentially curative surgical procedure that reestablishes physiologic hepatopetal portal flow. It is typically accomplished by interposing a vascular conduit between the superior mesenteric vein to the still patent intrahepatic portal venous system. This procedure results in resolution of portal hypertension.
本文旨在阐述经 Rex 分流术前、后评估的肝外门静脉阻塞患者的影像学特征。
Rex 分流术是一种有潜在治愈可能的手术，可重建生理性向肝门静脉血流。该手术通常通过在肠系膜上静脉与仍通畅的肝内门静脉系统之间置入血管导管来完成。该手术可导致门静脉高压症得到缓解。
