[Mechanical obstruction of the duodenum after surgery of the abdominal aorta]

The authors report two cases of duodenal obstruction occurring after insertion of an aorto-iliac prosthesis. This form of mechanical obstruction is much rare than the other forms of post-operative mechanical intestinal obstruction. While the need for surgery is often evident, precise diagnosis before the procedure is seldom obtained. CT scan appears to be the investigation of choice. This complication could be prevented by an epiploplasty covering the graft implant region.
