Percutaneous Treatment of Vertebral Artery Stenosis

Endovascular treatment of the ostial and proximal portions of the vertebral artery is a safe and effective technique for alleviating symptoms and improving cerebral blood flow to the posterior circulation. Vertebral artery angioplasty can be performed with high technical and clinical success rates, low complication rates, and durable long-term results. Although restenosis rates range from 0% to 48%, the durability of vertebral artery angioplasty is evidenced by low restenosis rates in multiple large series reported in the literature using multiple treatment options, including balloon angioplasty alone, bare metal stents, and drug-coated stents.
