Implication

Cohort study reveals transcutaneous oxygen pressure predicts wound healing in peripheral vascular disease amputations, suggesting an objective threshold to preserve limb length.

Key Points

To evaluate whether transcutaneous oxygen pressure (TcpO2) measurement can reliably assess tissue viability and predict wound healing to guide the selection of distal amputation levels.
Evaluated preoperative TcpO2 and ankle systolic pressure in 59 patients undergoing 62 lower limb amputations for peripheral vascular disease.
Tracked postoperative healing outcomes across below-knee and above-knee amputation sites relative to measured oxygenation thresholds.
Below-knee amputations with preoperative TcpO2 levels >35 mmHg consistently achieved wound healing, whereas all healing failures exhibited levels ≤35 mmHg.
Nine of sixteen patients (56.3%) who received above-knee amputations demonstrated below-knee TcpO2 values >35 mmHg, identifying them as potential candidates for successful below-knee procedures.
No significant correlation was observed between ankle systolic pressure measurements and amputation wound healing success.
