Updated Guidelines on Perioperative Management of Anticoagulant and Antiplatelet Therapy for Interventional Techniques – Pain Physician

18 Aug, 2024 | 14:52h | UTC

Introduction: The American Society of Interventional Pain Physicians (ASIPP) has published updated guidelines for the perioperative management of patients undergoing interventional techniques while receiving antiplatelet and anticoagulant therapy. These guidelines are essential for clinicians to balance the risk of thromboembolism against the risk of bleeding during interventional procedures.

Key Points:

1 – Risk of Thromboembolic Events:

– Thromboembolic events have a higher risk of morbidity and mortality compared to the risk of epidural hematoma. Thus, interruption of antithrombotic therapy should be carefully considered.

2 – Risk Stratification of Procedures:

– Interventional techniques are classified into three categories based on risk: low, moderate, or high. For high-risk procedures, cessation of anticoagulant or antiplatelet therapy is recommended, whereas for low to moderate-risk procedures, therapy may continue under certain conditions.

3 – Management of Direct Oral Anticoagulants (DOACs):

– DOACs such as dabigatran, apixaban, rivaroxaban, and edoxaban should generally be discontinued for 2 days before high-risk procedures and one day for moderate-risk procedures. Adjustments are needed based on renal function, specially for dabigatran.

4 – Discontinuation of Aspirin:

– For high-risk interventional procedures, discontinuation of aspirin (81 or 325 mg) is recommended 6 days before the procedure. However, for low to moderate-risk procedures, aspirin therapy may be continued or stopped for 3 days depending on individual risk factors and clinical judgment.

5 – Discontinuation of Other Antiplatelet Agents:

– Clopidogrel (Plavix) and Prasugrel (Effient): These agents should be discontinued 6 days before high-risk procedures. For low-risk procedures, these medications can be continued.

– Ticagrelor (Brilinta): Discontinue for 5 days before high-risk procedures, with consideration of patient-specific risk factors.

6 – Timing for Restarting Therapy:

– Antithrombotic therapy should typically be resumed within 12-24 hours after low to moderate-risk procedures and within 24-48 hours after high-risk procedures, depending on bleeding risk and patient status.

7 – Shared Decision-Making:

– Decisions on whether to continue or discontinue antithrombotic therapy should involve shared decision-making between the patient, the interventional pain specialist, and other treating physicians, considering all associated risks.

Conclusion: These guidelines provide a comprehensive framework for managing the delicate balance between thromboembolic and bleeding risks in patients on anticoagulant or antiplatelet therapy undergoing interventional procedures. They emphasize the importance of personalized care and multidisciplinary collaboration.
