Mesenteric arteriovenous fistulas are a rare entity. Those involving the inferior mesenteric artery are exceptionally rare with only 13 cases reported in the English literature,1,2 of which only one has been associated with ischemic colitis. Ischemic colitis is a well-recognized clinical entity that typically occurs spontaneously in elderly patients and is not associated with a specific clinical presentation.3 We report a case of ischemic colitis caused by venous hypertension associated with a congenital inferior mesenteric arteriovenous fistula. To our knowledge, this is the first reported case of a mesenteric arteriovenous fistula causing ischemic colitis in a patient without previous gastrointestinal surgery or trauma.
肠系膜动静脉瘘是一种罕见的病症。累及肠系膜下动脉的情况极为罕见，英文文献中仅报道过13例，其中仅有1例与缺血性结肠炎相关。缺血性结肠炎是一种公认的临床病症，通常在老年患者中自发出现，且无特定的临床表现。我们报告了一例因先天性肠系膜下动静脉瘘导致静脉高压引起的缺血性结肠炎病例。据我们所知，这是首例报道的在无既往胃肠道手术或创伤的患者中由肠系膜动静脉瘘引起缺血性结肠炎的病例。
