Ankle systolic pressure index and early vein graft failure.

Abstract

To the Editor. —The article by Corson et al in the August 1978 issue (113:932-935) bears comment relative to their finding of no correlation between the ankle systolic pressure index (ankle pressure divided by brachial pressure) and the incidence of early failure of saphenous vein grafts. The authors have correctly quoted our article 1 showing a highly significant correlation between low ankle pressure indices ( It can be argued that the ankle pressure indices in the 20 patients who had distal bypasses were probably concentrated in the
