Percutaneous transluminal angioplasty for subclavian artery stenosis.

Treatment of brachiocephalic arterial lesions by percutaneous transluminal angioplasty (PTA) has only recently been performed with sufficient frequency to allow full assessment of its value. In this series, we report our results with PTA of 36 symptomatic subclavian stenoses in 33 patients seen from February 1981 through February 1992. Initial success rate was 94 per cent. There were no deaths and no CNS complications. Five minor complications occurred. Review of published surgical series suggests a similar early success rate but a significantly higher morbidity. These excellent early results of PTA and long-term results from other studies confirm that PTA of subclavian artery stenoses is a safe, highly effective procedure and should be considered the treatment of choice for symptomatic subclavian artery stenoses.
