  • Title: Percutaneous angioplasty for peripheral arterial occlusive disease. Correlates of clinical success.
    Author: Cambria RP, Faust G, Gusberg R, Tilson MD, Zucker KA, Modlin IM.
    Journal: Arch Surg; 1987 Mar; 122(3):283-7. PubMed ID: 2950841.
    Abstract:
    We reviewed 142 percutaneous transluminal angioplasties (PTAs) in the iliac (n = 94) and femoropopliteal (n = 48) positions of 107 patients. Emphasis was placed on the ultimate clinical outcome, which was determined from a pool of clinical, hemodynamic, and angiographic data. Limb-threatening ischemia was the indication for intervention in 53% of the cases. The median follow-up interval was 17 months. Overall success was achieved in 50% of cases in both iliac and femoral positions at one year after PTA. The following factors were found to correlate with a successful clinical outcome: PTA for claudication vs limb-threatening ischemia (P less than .001); focal as opposed to diffuse stenosis or occlusion (P less than .02); immediate return of distal pulses (P less than .001); the absence of diabetes (P less than .05); and the presence of a patent outflow tract (P less than .001). Treatment results with PTA will vary widely according to the nature of the patient population and the criteria for determining success.
