Abstract

When the portal hypertension syndrome occurs, patients with liver cirrhosis develop three major collateral blood flow pathways. These are gastroesophageal, splenorenal, and paraumbilical ones along the recanalized umbilical veins. Only both the splenorenal pathway of blood return from the portal venous system, which considerably reduces portal blood flow volume and the paraumbilical one that increases portal blood flow are of hemodynamic significance.

摘要

当门静脉高压综合征发生时，肝硬化患者会形成三条主要的侧支血流途径。这些途径分别是胃食管途径、脾肾途径以及沿重新开放的脐静脉形成的脐旁途径。只有来自门静脉系统的脾肾回血途径（该途径可显著减少门静脉血流量）以及增加门静脉血流量的脐旁途径具有血流动力学意义。
