title: [Percutaneous transluminal angioplasty of supra-aortic vessels. Presentation of 16 cases].
abstract: Sixteen cases are reported of dilatation of supra-aortic vessels; in 14/16 patients the vessel involved was either the subclavian artery or the brachiocephalich trunk. Special attention is paid to the choice of patients--the ideal one presenting with a single uncalcified lesion, with stenosis more than 50% of diameter; the symptoms have recently appeared, with a significant difference (more than 20 mmHg) in the pressure of the two arms. The technical aspects of the angioplastic procedure are discussed, especially in order to preserve the intracranial circulation and to limit possible complications. The presence of reversed blood flow in the vertebral artery is extremely important to preserve intracranial circulation from possible embolism; normal flow obtained at the end of the procedure is therefore an useful proof of successful dilatation. The advantages are stressed of dilatation over the surgical techniques used in the past. Finally, the importance is emphasized of a correct follow-up and doppler control of supra-aortic circulation.
