Arterial thromboembolectomy--should anticoagulants be administered?
Acta Chirurgica Scandinavica
|August 1, 1986
Summary
Anticoagulants like heparin and coumarin are often used in acute limb ischemia surgery. This study found no definite evidence of their benefit, suggesting a need for further trials.
Area of Science:
- Vascular Surgery
- Thromboembolic Disease Management
Background:
- Perioperative anticoagulation with heparin and coumarin is standard for acute limb ischemia (ALI).
- The efficacy of anticoagulants in arterial thromboembolectomy for ALI remains debated.
Purpose of the Study:
- To compare outcomes of arterial thromboembolectomy with and without perioperative anticoagulation.
- To evaluate the impact of anticoagulants on recurrence rates and hospital mortality in ALI patients.
Main Methods:
- Retrospective analysis of arterial thromboembolectomy cases with and without anticoagulants.
- Review of 15 published series on acute limb ischemia management.
Main Results:
- Adequately anticoagulated patients showed more good results, but hospital death rates were similar.
- Selection bias may have influenced better outcomes in the anticoagulated group.
- Long-term anticoagulation did not significantly reduce thromboembolism recurrence.
Conclusions:
- Current evidence for the benefit of perioperative anticoagulation in ALI is lacking.
- No significant difference in outcomes was observed between centers using and not using postoperative anticoagulants.
- A prospective randomized trial is necessary to definitively assess the role of anticoagulants in ALI treatment.
