Application of covered stent in peripheral vessels

The application of covered stent in vascular malformation such as aneurysm, pseudoneurysm (PSA), arteriovenous fistula(AVF)has outcome to an encouraging result. Recently, it has also been effectively used for PTA, TIPS, traumatic lesions of peripheral vessels, and pseudoneurysm of dialysis grafts, etc. But there still remain some issues on the restenosis and endothelialization after the performance with covered stent. This review will pay attention to them. (authors)
