    Delaying emergency amputations with cryoamputation in critically ill patients may improve outcomes. This technique allows for patient stabilization before surgery, potentially reducing high mortality rates associated with immediate operative procedures.

    Area of Science:

    • Surgical Innovation
    • Critical Care Medicine
    • Limb Salvage

    Background:

    • Emergency amputations in critically ill patients carry high morbidity and mortality risks.
    • Immediate operative procedures for severe limb ischemia or infection often lead to poor patient outcomes.

    Purpose of the Study:

    • To evaluate the impact of preoperative cryoamputation on patient outcomes.
    • To assess if delaying inevitable amputation via freezing improves survival in high-risk patients.

    Main Methods:

    • Retrospective review of 56 patients undergoing cryoamputation over 12 years.
    • Analysis of risk factors, sepsis, amputation level, morbidity, and mortality.
    • Comparison with primary operative major amputations.

    Main Results:

    • Overall mortality for cryoamputation was 14% (8/57), higher than primary amputations (7%).
    • Diabetes mellitus was a significant factor affecting survival in cryoamputation patients.
    • Cryoamputation allowed stabilization for critically ill, septic patients.

    Conclusions:

    • Cryoamputation is a valuable, simple technique for stabilizing high-risk patients before surgery.
    • This method can mitigate the high mortality associated with emergency amputations.
    • Careful patient selection and preparation are crucial for cryoamputation success.
