Portal hypertension caused by right common iliac artery-superior mesenteric vein fistula.

Portal hypertension caused by arterio-portal fistula between the right common iliac artery and superior mesenteric vein has not been reported. Here, we report such a case in a 35-year-old male without any history of liver disease or abdominal trauma. This case was confirmed by abdominal aorta angiography and three-dimensional angiography, and was successfully treated by a covered stent implantation in the right common iliac artery to block the fistula.
