[Percutaneous transluminal angioplasty in proximal subclavian stenoses].

Between August 1980 and June 1982, 12 left-sided proximal subclavian stenoses were dilated with balloon catheters. The dilatation was successful in all patients. Differences in blood pressure in the arm could be demonstrated subsequently. Recurrences occurred in two patients after seven and eleven months. Follow-up of nine patients up to 24 months showed them to be symptom-free.
