Summary

Managing antiplatelet agents before surgery involves balancing bleeding and clotting risks. While aspirin is often continued, clopidogrel discontinuation may cause thrombotic events, necessitating careful patient evaluation.

Area of Science:

  • Cardiology
  • Anesthesiology
  • Pharmacology

Background:

  • Antiplatelet agents like aspirin, clopidogrel, and glycoprotein (GP) IIb/IIIa inhibitors are crucial for preventing arterial thrombosis.
  • Their use in patients undergoing surgery presents a dilemma between hemorrhagic and thrombotic risks.

Purpose of the Study:

  • To review surgical risks associated with antiplatelet agents.
  • To outline principles for evaluating and managing these risks.

Main Methods:

  • A narrative review of existing medical literature in English and French.

Main Results:

  • Continuing aspirin is often recommended for vascular procedures with low bleeding risk.
  • Stopping clopidogrel five days prior may lead to thrombotic events in urgent cases.

Related Experiment Videos

  • Glycoprotein IIb/IIIa inhibitors should be withdrawn before surgery to reduce bleeding.
  • Platelet transfusions are reserved for patients with abnormal bleeding due to antiplatelet effects.

    • Conclusions:

    • Data on managing antiplatelet therapy in surgical patients, particularly non-cardiovascular, is limited.
    • Further clinical trials are essential to guide patient management.
