The aortovenous fistulas are rare, most of them are aortocaval fistula. The non-caval communication of the fistula is sparse. Herein we report a 47-year-old female diagnosed as traumatic aorto-superior mesenteric vein (Ao-SMV) fistula. The abdominal pain, fullness, and frank bruit on abdominal auscultation suggested the diagnosis of an intra-abdominal arteriovenous fistula. The diagnosis of Ao-SMV was further confirmed by the computed tomography (CT) and aortography. The fistula was successfully treated with transcatheter coil embolization. This is the first case of Ao-SMV fistula. It provides an alternative option of treatment other than conventional surgery.

The aim of the present study was to investigate the effects and safety of a patent ductus arteriosus occluder (PDAO) in the management of major abdominal arteriovenous fistula. A 56-year-old man was admitted into our hospital, presenting with impeded defecation and claudication. Computed tomographic angiography (CTA) was conducted upon admission, which revealed an aneurysm-like lesion, with the left internal iliac artery as its feeding artery. Super-selective embolization treatment was accomplished using a single PDAO. The results of the CTA at follow-up showed no recanalization of the lesion and that a PDAO was at the site. The patient had no pelvic ischemia complications.
