The application of percutaneous transluminal angioplasty (PTA) in the treatment of arteriosclerotic occlusive disease is relatively new in the USA. To ascertain more data on case selection, procedure and success rate, 100 consecutive patients were evaluated as possible candidates for treatment with PTA. Patients were divided into 5 groups on the basis of procedural acceptability. PTA was indicated for 71% of the patients. Arteries (117) were treated in 56 patients with a primary success rate of 91.5% of the arteries (82% of the patients). PTA is a potentially effective treatment with arteriosclerotic occlusive disease.
