This case report details a technique to intraoperatively define a segment of small bowel containing a bleeding arteriovenous malformation allowing definitive surgery. A patient with an arteriovenous malformation of the small intestine underwent angiographic localization using a highly selective microcatheter and intraoperative methylene blue dye allowing a specific segment of intestine to be resected. Angiographic identification and intraoperative location of small intestine arteriovenous malformations can allow the surgeon to more accurately define the affected segment allowing the surgery to be specific and successful.

    Multiple spinal dural arteriovenous fistulas (DAVFs) have been rarely reported and only two such cases are found in the literature. A 71-year-old man complained of muscle weakness and hypesthesia in both legs and angiographically diagnosed as thoracic DAVF. The fistula was surgically treated,...
