Retrograde mesenteric stenting during laparotomy for acute occlusive mesenteric ischemia

Retrograde superior mesenteric artery (SMA) injection. Note the proximity of the sheath’s point of entry (black arrow) and of the sheath’s tip (white arrow) to the proximal SMA occlusion. There is no reflux of contrast into the aorta.

A, Intraoperative lateral fluoroscopic image shows two stents (underscored by a white line) deployed in the superior mesenteric artery (SMA) origin with the 0.018-inch wire still in place. Note the lumbar vertebral bodies to the left. B, Completion retrograde arteriogram shows free reflux of contrast into the aorta and no residual angiographic stenosis; P denotes the approximate location of the SMA patch angioplasty.
