The differences in early haemodynamic response between surgery and angioplasty after successful re-opening of the superficial femoral artery.
In 40 patients with superficial femoral artery disease we prospectively evaluated the effect of angioplasty (n = 20) or femoropopliteal bypass (n = 20) on the ankle-brachial pressure index (ABI) using the Doppler ultrasound probe. The ABI was measured as a baseline 1 day before the procedure, 1 day after the procedure and 30 days later. In the angioplasty group the baseline ABI was 0.57 (0.11), increasing to 0.74 (0.26) 1 day postangioplasty and increasing further to 0.88 (0.26) after 30 days. The increase in ABI over 30 days was significantly greater than the increase over 1 day. In the femoropopliteal bypass group the baseline ABI was lower at 0.46 (0.17). However 1 day postoperatively it had increased to 0.92 (0.2) with almost no further increase at 30 days [0.95 (0.17)]. We concluded that by contrast to a surgical bypass where there was a large improvement in the ABI over the first day, the ABI following angioplasty continued to improve significantly beyond the first day.
