Ectopic varices have been reported in 5% of children presenting with variceal bleeding and are defined as portosystemic venous collaterals occurring anywhere in the abdomen except in the cardioesophageal region. The liver-intestinal transplant or isolated liver-intestinal transplant patient presenting several years post-transplant with ectopic variceal bleeding as a consequence of portal hypertension is a seldom reported complication. Etiologies such as rejection or infection are a more common source of bleeding, and only after excluding these can differentials such as portal hypertension secondary to a blocked portacaval shunt or native liver disease be considered.
据报道，5% 的静脉曲张出血儿童存在异位静脉曲张，其定义为发生在腹部除心食管区域以外任何部位的门体静脉侧支循环。肝肠移植或单纯肝肠移植患者在移植数年之后因门静脉高压出现异位静脉曲张出血，这是一种鲜有报道的并发症。诸如排斥反应或感染等病因是更常见的出血来源，只有在排除这些病因之后，才能考虑诸如门腔分流堵塞继发门静脉高压或原发病肝病等鉴别诊断。
