[Percutaneous transluminal angioplasty of the iliac arteries. Immediate and long-term results].
Percutaneous transluminal angioplasty (PTA) was performed 30 times in 28 patients aged from 31 to 77 years (mean: 50.8 years) with stenosis of the iliac arteries. All patients were evaluated before and immediately after PTA by measuring the trans-stenotic pressure gradient and the degree of angiographic stenosis (grade 1 less than or equal to 50%; grade 2 = 50 to less than 75% and grade 3 greater than or equal to 75%). Prior to PTA 27 patients had grade 3 and three patients had grade 2 stenosis. The figures after PTA were 23 grade 1 and seven grade 2 stenosis. The mean trans-stenotic pressure gradient was reduced from 43 +/- 35 to 2.3 +/- 5.9 mmHg, the difference being highly significant (p less than 0.001). Eighteen patients were evaluated clinically and angiographically 8.4 +/- 6.1 months after PTA. Considerable clinical improvement was observed in 15, and 16 had a residual stenosis of less than 50%. PTA therefore appears to be a satisfactory treatment of stenosis of the iliac arteries. The long-term results can be assessed by graded intravenous angiography without any risk of damage to the arteries.
