Abstract english

The prognostic value of distal blood pressure measurements has been studied in 314 consecutive diabetic patients with foot ulcers. Systolic toe blood pressure was measured with a strain-gauge technique, and ankle pressure was measured with strain-gauge or Doppler techniques. Wound healing was defined as intact skin for at least 6 mo. One hundred ninety-seven patients healed primarily, 77 had amputations, and 40 died before healing had occurred. In 294 of 300 patients, it was possible to measure either ankle or toe pressure. Fourteen patients were not available for pressure measurements. Of these, 10 patients healed primarily, and 4 died before healing occurred. Both ankle and toe pressures were higher (P less than .001) among patients who healed without amputation compared with those who underwent amputation or died before healing. No differences were seen in ankle or toe pressure levels among those who had amputations or died. No patient healed primarily with an ankle pressure less than 40 mmHg. An upper limit above which amputation was not required could not be defined. Primary healing was achieved in 139 of 164 patients (85%) with a toe pressure level greater than 45 mmHg, whereas 43 of 117 patients (36%; P less than .001) healed without amputation when toe pressure was less than or equal to 45 mmHg. In conclusion, a combination of ankle and toe pressure measurements is a useful tool to predict primary healing in diabetic foot ulcers.
