Results of percutaneous transluminal angioplasty

Abstract

Percutaneous transluminal angioplasty (Dotter technique) was used in 2,942 cases of iliofemoral atheromatous disease. Results varied with the characteristics of the obstructing lesion (length and location) and the clinical stage of ischemia (claudication, rest pain, gangrene). Based on the foregoing, angioplasty is done either as the preferred primary treatment or for the relief of clinically advanced disease in patients unsuitable for high risk surgery. Success is favored by the use of aggregation inhibitors and single-use Teflon or balloon catheters; complications are few.
