[Catheter dilatation of arterial stenoses of supra-aortic vessels and late results].

Arterial stenoses of supra-aortic vessels, particularly of the subclavian and vertebral arteries, can be successfully treated by percutaneous transluminal angioplasty (PTA). In 125 patients primary success was achieved in 93% by PTA; 84 patients have been followed up for an average of 46 months and a clinical cure rate of 98.8% has been achieved. Apart from one re-stenosis all patients were symptom free and no other re-stenoses could be demonstrated. PTA of occlusions of supra-aortic vessels has less chances of success.
