Stent Migration during Endovascular Treatment of Traumatic Arteriovenous Fistula following Lumbar Spine Surgery.

We report the endovascular treatment of an arteriovenous fistula involving the right common iliac artery (CIA) and left common iliac vein in a 48-year-old male patient who had previously undergone lumbar spine disc surgery. A balloon expandable covered stent was deployed in the CIA which got partially dislodged into the aorta during attempted postdilatation of the stent. The proximal end of the stent was secured in place with an inflated balloon in the aorta, introduced from the contralateral iliac artery, allowing successful retrieval and dilatation of the stent graft through the ipsilateral femoral vascular access. The stent migration was managed without complications, and the fistula was successfully occluded.
