Abstract：
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.
摘要：
异位静脉曲张可以定义为位于食道或胃以外的部位的扩张的门体静脉侧支。这些静脉曲张可以在潜在的门静脉高压症患者中看到，但出血很少见.出血通常发生在有腹内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，但是它们可以出现在胃肠道的任何地方。目前,没有关于这些静脉曲张出血的诊断和治疗的既定指南，需要进一步的随机对照或大规模试验研究。这里,我们报告了一例因回肠动静脉畸形（AVM）引起的异位静脉曲张破裂出血，在没有腹部手术史的患者中，表现为与急腹症相关的晕厥。
