Emergent stent graft isolation of a knife‐related subclavian arterial venous fistula: Lessons learned during long‐term follow‐up

We present the unusual case of a 42‐year‐old gentleman who entered the trauma center with a hemothorax and intermittent bright red pulsatile blood from three stab wounds in the ipsilateral supraclavicular fossa. The patient was found on emergent angiography to have a large right subclavian artery to vein fistula that was treated successfully with a Dacron‐covered stent. Angiography, 2 years following stent‐graft isolation, confirmed a durable result with evidence of hemodynamically insignificant neointimal growth through the pores of the graft material. This case provides insight into the long‐term effects of a Dacron‐covered stent in patients with traumatic arterial injury. We discussed the advantages and disadvantages of different graft materials based on these angiographic findings. © 2005 Wiley‐Liss, Inc.
