摘　　要：十二指肠异位静脉曲张（DV）为罕见的发生于胃、食管之外的静脉曲张,为异位静脉曲张的主要类型.病因多见于肝硬化、门静脉高压、肝外门静脉闭塞、血管炎.其独特的病生理机制、位置特殊性、形态多样性、疗效不确定性决定了其低发现率和高死亡率.DV的诊断与治疗仍是临床工作中的一大难题,通过从病理生理机制、诊断和治疗方法等方面探讨DV的临床研究现状与进展,以期为临床诊治提供参考.Duodenal varices are an uncommon disease which occurs along the entire gastrointestinal tract outside the esophagus or stomach.Among ectopic varices,duodenal varices are the most common one.Cirrhosis,hepatic portal hypertension,extrahepatic portal vein occlusion and vasculitis contribute to the pathogenesis of ectopic variceal formation.The unusual pathophysiology,location,diversity and uncertain curative effect of DV are associated with its low detection rate and high mortality of patients.Therefore,the diagnosis and treatment of DV is one of the tough problems in clinical practice.This article reviews the current research advances in pathophysiology,diagnosis and treatment of duodenal varices to provide reference for clinical practice.
