Abstract
Direct measurement of the femoral artery pressure before operation has been used to
predict the postoperative change in ankle and toe pressure in 102 limbs (83 patients)
that underwent aortoiliac surgery for the treatment of atherosclerotic occlusion or
stenosis affecting both the aortoiliac and femoral artery segments. Rest pain or gangrene
was present in 74 limbs. In 26 other limbs simultaneous aortoiliac and femoral artery
reconstructions were performed. The changes in both toe and ankle pressures could
be confidently predicted from the preoperative data. A predicted toe pressure of lower
than 25 mm Hg was associated with a high probability that amputation would be required.
The chances of an amputation were less than 3% if a toe pressure higher than 40 mm
Hg was predicted. If the predicted ankle pressure index was lower than 0.56, there
was a 90% chance that intermittent claudication would persist. Measurement of the
femoral artery pressure allows prediction of the toe and ankle pressure response to
surgery to be made with sufficient accuracy to permit a preoperative decision to be
made between the need for a single-level or a two-level arterial reconstruction: no
patients who had an aortoiliac reconstruction needed a subsequent downstream repair
of the femoral segment.
