5. Study Description
Brief Summary
The purpose of this study is to determine whether DEB is not inferior to common bare metal stent using under in long-term vessel patency and inhibiting restenosis in Vertebral Artery Ostium Stenosis
Detailed Description
Vertebral Artery Origin Stenting is an established alternative to open surgical bypass for the treatment of Vertebral Artery Ostium Stenosis .
DEBs are designed to promote arterial patency by reducing neointimal proliferation.
