Ectopic varices can be defined as dilated portosystemic venous collaterals that are located at a site other than the esophagus or stomach. These varices can be seen in patients with underlying portal hypertension, but bleeding from them is quite rare. The bleeding usually occurs in patients with a history of intra-abdominal surgery and adhesions. These varices are commonly found in the duodenum or rectum, but they can be present anywhere along the gastrointestinal tract. Currently, there are no well-established guidelines regarding the diagnosis and management of these variceal bleeds, and further investigations with randomized controlled or large-scale trials are required. Here, we report an unusual case of ectopic variceal bleeding from an ileal arteriovenous malformation (AVM), which presented as syncope associated with an acute abdomen in a patient with no prior history of intra-abdominal surgery.
异位静脉曲张可定义为位于食管或胃以外部位的扩张的门体静脉侧支循环。这些静脉曲张可见于潜在门静脉高压患者，但由此导致的出血相当罕见。出血通常发生在有腹部手术和粘连病史的患者中。这些静脉曲张常见于十二指肠或直肠，但也可出现在胃肠道的任何部位。目前，关于这些静脉曲张出血的诊断和管理尚无完善的指南，需要进行随机对照或大规模试验的进一步研究。在此，我们报告一例罕见的回肠动静脉畸形（AVM）导致的异位静脉曲张出血病例，该病例表现为一名无腹部手术史患者出现与急腹症相关的晕厥。
