Amputation of the Ischemic Limb: Selection of the Optimum Site by Thermography

Abstract

This report describes the value of infrared thermography in assessing the optimum level of amputation of an ischemic limb. Interpretation of thermo- grams and the factors that can significantly alter the thermal image of the lower limbs are detailed. Results from 104 patients demonstrate that the thermographic method is a reliable indicator of the level of a major limb amputation. A rationale for the inadequacy of the method when attempting to determine the outcome of a partial foot amputation is considered.
