Inferior mesenteric arteriovenous fistula (IMAVF) is a rare condition with 40 reported cases. It can be of congenital, idiopathic or acquired etiology. Acquired IMAVF occurs after trauma or has an iatrogenic origin due to abdominal interventions, mainly operations involving the left hemi-colon. A new case of iatrogenic IMAVF is described, which became symptomatic 13 years after right hemicolectomy and was diagnosed radiologically one year later. This case was treated successfully by means of endovascular arterial embolization. To our knowledge, this is only the second reported case of acquired IMAVF following right hemicolectomy.
肠系膜下动静脉瘘（IMAVF）是一种罕见疾病，仅有40例报告病例。其病因可为先天性、特发性或后天性。后天性IMAVF发生于创伤后，或因腹部干预，主要是涉及左半结肠的手术而具有医源性起源。本文描述了一例医源性IMAVF新病例，该病例在右半结肠切除术后13年出现症状，一年后经放射学诊断。该病例通过血管内动脉栓塞术成功治愈。据我们所知，这是右半结肠切除术后获得性IMAVF的第二例报告病例。
