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.
