Determination of Amputation Level in Ischemic Limbs: Reappraisal of the measurement of TcPo2

Abstract

Preoperative TcPo2 measurement may be of considerable help to predict stump outcome and level of amputation. Our study provides objective prognostic values for the range 0-50 mmHg and suggests that TcP02 should usually be 20 mmHg at the site of amputation, which will predict healing with 80% accuracy and should, therefore, not be used as a sole criteron. Despite this aid in making his decision about the amputation level, the surgeon still has to balance between his goal of achieving primary wound healing and his hope of preserving the maximal limb length and has to consider patient preferences.
