Major amputation following vascular reconstructive procedures (including sympathectomy)

G Hunter, P Holliday

    Canadian Journal of Surgery. Journal Canadien De Chirurgie
    |September 1, 1978
    PubMed
    Summary

    Previous vascular surgery or sympathectomy increases below-knee amputation success rates but also revision procedures. However, revision surgeries do not impact lower limb amputation mortality.

    Area of Science:

    • Vascular Surgery
    • Amputation Procedures
    • Surgical Outcomes

    Background:

    • Vascular reconstruction and sympathectomy are interventions aimed at limb salvage.
    • The impact of these procedures on subsequent amputation levels and outcomes is not fully understood.
    • Understanding these effects is crucial for optimizing patient management and resource allocation in amputation care.

    Purpose of the Study:

    • To investigate the influence of prior vascular reconstruction or sympathectomy on amputation level.
    • To determine the effect of these vascular interventions on the number of revision procedures required post-amputation.
    • To assess the impact of vascular surgery or sympathectomy on mortality following lower limb amputation.

    Main Methods:

    • Retrospective review of 504 patient records from three Toronto teaching hospitals.

  • Analysis included patients undergoing amputation at or above the below-knee level.
  • Data collected focused on prior vascular interventions, amputation level, revision procedures, and mortality.

    • Main Results:

    • Previous vascular surgery or sympathectomy was associated with a higher success rate for below-knee amputations.
    • Failed vascular interventions led to an increased number of necessary revision procedures.
    • Revision procedures performed after amputation did not significantly affect overall mortality.

    Conclusions:

    • Prior vascular interventions can improve the success of below-knee amputations.
    • Vascular surgery or sympathectomy failures necessitate more revision procedures.
    • Revision procedures do not alter the mortality rates associated with lower limb amputations.
