Evaluates tissue perfusion improvement in ischemic limbs using infrared thermography after revascularization, suggesting better assessment methods.

To assess the feasibility of infrared thermography for evaluating tissue perfusion pre- and post-revascularization in critical limb ischemia.
Prospective evaluation of 30 patients with critical limb ischemia undergoing revascularization.
Thermographic measurements taken in a temperature-controlled environment at 26°C.
Mean surface temperatures recorded for the affected foot and anterior chest.
Calculated affected-to-chest temperature ratio and absolute temperature change (ΔT).
Clinical outcomes correlated with thermal changes.
Mean foot temperature increased from 29.7°C pre-revascularization to 32.2°C post-revascularization (P < 0.001).
Affected-to-chest temperature ratio improved from 0.85 to 0.92 (P < 0.001).
≥2°C temperature improvement was linked to higher rates of wound healing and limb salvage (r = 0.62, P < 0.01).
