Superior mesenteric artery angioplasty and stent

The arteriogram (A) shows filling of the jejunal, ileal, ileocolic, right colic, and middle colic arteries. There is a small amount of retrograde filling of the celiac axis via the pancreaticoduodenal arcade. The stenosis of the SMA is not visible on this view. A steep right anterior oblique view of the SMA (B) shows a short segment stenosis of the proximal SMA at its origin (thick arrow). A stent has been positioned in the proximal SMA (C) in the region of the stenosis (thin arrow) and expanded using a balloon. A selective SMA arteriogram (D) postangioplasty shows significant improvement in the severity of the stenosis following stent placement (arrowhead).
