Foot TcPO2 Response to Lumbar Sympathectomy in Patients with Focal Ischemic Necrosis

Foot TcPO2 Response to Lumbar Sympathectomy in Patients with Focal Ischemic Necrosis ) values of <30 mmHg who received a sympathectomy as the primary treatment of their vascular occlusive disease. Preoperatively, and every 2-3 days in the postoperative period, measurement of TcPO2 of the forefoot was performed. Clinical success was defined as healing of the necrosis or healing of a toe amputation and avoidance of a major below-knee/above-knee amputation for 1 year. Ten patients were available for long-term evaluation. During the first 4-5 days, all patients increased their foot TcPO2 and the mean increase (23 mmHg) was significant (p= 0.04). Clinical improvement was marked by an average increase of 29 mmHg by postoperative day 10. In contrast, patients with clinical failure had only an average increase of 5 mmHg in TcPO2 by the same postoperative interval. Preoperative increase in TcPO2 by at least 20 mmHg in response to dependency predicted a favorable response to sympathectomy. In addition, sustained postoperative increases in tissue oxygen levels by postoperative day 10 also favored wound healing. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annals of Vascular Surgery Springer Journals

Abstract

) values of <30 mmHg who received a sympathectomy as the primary treatment of their vascular occlusive disease. Preoperatively, and every 2-3 days in the postoperative period, measurement of TcPO2 of the forefoot was performed. Clinical success was defined as healing of the necrosis or healing of a toe amputation and avoidance of a major below-knee/above-knee amputation for 1 year. Ten patients were available for long-term evaluation. During the first 4-5 days, all patients increased their foot TcPO2 and the mean increase (23 mmHg) was significant (p= 0.04). Clinical improvement was marked by an average increase of 29 mmHg by postoperative day 10. In contrast, patients with clinical failure had only an average increase of 5 mmHg in TcPO2 by the same postoperative interval. Preoperative increase in TcPO2 by at least 20 mmHg in response to dependency predicted a favorable response to sympathectomy. In addition, sustained postoperative increases in tissue oxygen levels by postoperative day 10 also favored wound healing.
