Abstract
Twelve patients who have had an extended deep femoral angioplasty (EFDA) for severe lower limb ischaemia have been assessed. The patients underwent a standard exercise ankle pressure test before operation and 6 months after operation. The test included the measurement of resting brachial and ankle pressures, walking distance on a treadmill and the post-exercise pressure response. A limb ischaemic score was derived from these measurements; 8 patients showed an improved score, 3 patients exhibited no change and 1 was worse. The mean improvement in walking distance of the successful cases was 182 per cent (s.d. 96 per cent). There were no amputations during the period of study.
