Endovascular Stent Graft for Post-traumatic Superficial Femoral Artery Pseudoaneurysms with Arteriovenous Fistula: 6 Months Follow-Up of 2 Cases

Abstract

Pseudoaneurysms  are  common  vascular  abnormalities  due  to disruption  of  the  vessel  wall. Pseudoaneurysm with arteriovenous fistula is a rare presentation. Complications associated with them develop unpredictably and carry a high mortality rate. Traditionally pseudoaneurysms have been treated surgically. However, with  the  advent  of  new  interventional techniques, management  using  endovascular approach have gained popularity in treating  pseudoaneurysms. Here, we present two cases of large pseudoaneurysms with arteriovenous fistula treated by percutaneous stent graft. Present studies on pseudoaneurysms are all either iatrogenic or secondary to nephrologic dialysis treatment and only few present studies exist describing such large post-traumatic femoral pseudoaneurysms with arteriovenous fistulas were treated successfully by stent grafting through femoral approach, with good patency at 6 months follow up.
