Embolectomy for limb embolism significantly reduces perioperative mortality and improves long-term survival, especially with oral anticoagulant treatment. Further trials are needed for definitive conclusions on amputation rates.

Area of Science:

  • Vascular Surgery
  • Cardiology
  • Pharmacology

Background:

  • Embolectomy is a critical intervention for acute limb ischemia.
  • High mortality rates are associated with extremity embolectomy.

Purpose of the Study:

  • To evaluate factors influencing outcomes after extremity embolectomy.
  • To assess the impact of oral anticoagulant therapy on perioperative and long-term survival.

Main Methods:

  • Retrospective analysis of 221 patients undergoing extremity embolectomy.
  • Evaluation of patient demographics, clinical factors, and treatment outcomes.
  • Statistical analysis of mortality, amputation rates, and survival.

Main Results:

  • Perioperative mortality was 37%, with higher rates in hospitalized patients and those with myocardial infarction.

  • Oral anticoagulant treatment was associated with significantly lower perioperative mortality (5% vs. 51%) and improved 5-year survival (43% vs. 12%).
  • Patient age, coronary artery disease, and anticoagulant use independently influenced early postoperative morbidity.

    • Conclusions:

    • Oral anticoagulant therapy appears to be a significant factor in reducing mortality and improving survival after extremity embolectomy.
    • Time to embolectomy did not correlate with amputation rates.
    • Further prospective studies are warranted to confirm these findings and clarify the role of anticoagulation.
