A Pilot Study Investigating the Use of Regional Oxygen Saturation as a Predictor of Ischemic Wound Healing Outcome after Endovascular Treatment in Patients with Chronic Limb-Threatening Ischemia.

ABSTRACT: Objective: To determine the prognostic value of regional tissue oxygenation saturation (rSO₂) for ulcer healing after endovascular treatment (EVT) of peripheral arterial disease (PAD). Materials and Methods: Among PAD patients, 34 patients with chronic limb-threatening ischemia underwent EVT for limb salvage. We retrospectively analyzed the cutoff rSO₂ values on postoperative day 1 to predict ulcer healing and patient prognosis. Skin perfusion pressure (SPP) and transcutaneous oxygen pressure (TcPO₂) were also used to assess wound healing. Results: A finger-mounted tissue oximeter can easily measure rSO₂ on the dorsal foot. Among the 34 patients, the ulcer healed in 25, and no changes were observed in 2 patients at 1 month af
