[Transluminal therapy of stenosing lesions of the supra-aortic vessels. Personal experience]

Percutaneous transluminal angioplasty (PTA) is commonly used to treat peripheral vascular diseases, but its use has recently spread to the treatment of stenotic lesions involving the supra-aortic vessels. The authors report their initial experience in 10 patients with left subclavian artery stenoses--8 of them treated with PTA and 2 with PTA and vascular stenting--and two more patients with fibromuscular stenosis of the internal carotid artery (ICA), which was treated by means of PTA. In the authors' opinion, PTA can be considered the procedure of choice to treat the stenotic lesions of the supra-aortic vessels. Intravascular stents can be extremely useful to prevent post-PTA restenosis, but further experience and probably further technological refinements are needed. To conclude, PTA of ICA is an effective method in selected cases--e.g., in the patients with symptomatic hemodynamic lesions and low risk of embolism, in the patients with difficult surgical access or in the event of high anesthesiological and/or surgical morbidity.
