Complications and bail-out situations during AAA endovascular repair.

The endovascular stent-graft is now a universally accepted treatment for abdominal aortic aneurysms but remains nonetheless experimental. There are generic aspects of endograft insertion as well as device specific deployment issues. There are a number of potential procedural complications, related to vascular access and to the deployment sequence. The common technical problems are described and, where possible, the endovascular solutions are outlined.
