there was one reported case of bowel ischemia requiring intestinal resection after coil embolization . Not

surprisingly, it appears that the risk of coil migration is increased in patients with a short, wide fistula neck.

Although no complications were reported in the seven patients treated with covered stents, the drawbacks
associated with SMA stent grafting should not be neglected; these potential complications include the need
for large access sheaths, difficulty cannulating the SMA ostia, intraoperative thromboembolism, and risk of
subacute or late stent thrombosis which could lead to acute or chronic bowel ischemia. Therefore, the risks
and benefits for each patient should be individually characterized before an operative decision is made.
We empirically recommend dual antiplatelet therapy in the three-month postimplantation period with
subsequent life-long treatment with aspirin and regular duplex surveillance for stenosis/occlusion.

In conclusion, SMAVF is a rare pathology observed after abdominal injury. Although severe morbidity can
occur if left untreated, these anomalous connections can be safely intervened upon to relieve symptoms with
covered stents.
