Abstract: Between 1986 and 1992, 308 percutaneous transluminal angioplasties in 252 patients were reviewed in the vascular laboratory of the Austin Hospital. The follow-up period ranged from 1 month to 6 years. Treadmill exercise testing was used as an additional mode of assessment to resting ankle/brachial pressure indices in monitoring outcome. Early haemodynamic improvement rate was 86.7%. In 267 successful cases, 199 had increased the mean(s.d.) resting ankle/brachial pressure index from 0.68(0.15) to 0.96(0.14) (P < 0.05) and another 68 with normal or unchanged resting ankle/brachial pressure indices after the procedure increased the mean(s.d.) post-exercise pressure index from 0.45(0.24) to 0.82(0.23) (P < 0.05). The primary haemodynamic improvement rate of initially successful percutaneous transluminal angioplasties was 80.1% at 1 year and was maintained in 46.1% of cases 5 years after. Treadmill exercise testing revealed reduction of the ankle/brachial pressure index in 69 patients during follow-up, indicating restenosis of the dilated lesion or development of a new arterial stenosis. Fifty-two of the 69 patients exhibited a significant drop in the resting pressure index. However, in the 17 remaining patients, only the post-exercise index decrease indicated haemodynamic deterioration. Treadmill exercise testing proved to be valuable adjunct in detecting haemodynamic changes after percutaneous transluminal angioplasty.
