Current concepts of the interventional treatment of proximal supraaortic vessel stenosis.

Interventional therapies using angioplasty and stenting of symptomatic stenosis of the proximal supraaortic vessels have evolved as safe and effective treatment strategies. The aim of this paper is to summarize the current treatment concepts for stenosis in the subclavian and brachiocephalic artery with regard to clinical indication, interventional technique including selection of the appropriate vascular approach and type of stent, angiographic and clinical short-term and long-term results and follow-up. The role of hybrid interventions for tandem stenoses of the carotid bifurcation and brachiocephalic artery is analysed. A systematic review of data for angioplasty and stenting of symptomatic extracranial vertebral artery stenosis is discussed with a special focus on restenosis rate.
