Superior mesenteric arteriovenous fistula (SMAVF) is a rare vascular disorder. The clinical presentation of SMAVF is atypical, depending on the size and location of the fistula.
Potential treatment of mesenteric AVFs is surgical correction of the AVFs with or without bowel resection. Another choice is percutaneous endovascular treatment. We present an unusual case of a 54-year-old man with crampy abdominal pain, initially thought to be ischemic bowel from mesenteric vein thrombosis. Further workup revealed multiple SMAVFs.
