Perioperative Management of Antithrombotic Therapy in Patients Undergoing Plastic and Reconstructive Surgery: A Practical Tool Based on Current Guidelines

Introduction: Given the aging population, plastic surgeons are increasingly faced with the challenge of balancing procedural bleeding risk with thromboembolic risk in patients receiving antithrombotic therapies undergoing elective procedures. Guideline recommendations remain unclear in this population, which contributes to heterogeneity in clinical practices. We present a practical approach that summarizes guideline recommendations to facilitate the perioperative management of patients requiring surgery who are already on antithrombotic agents. Methods: Due to the scarcity of plastic surgery-specific guidelines, recommendations were primarily adapted from the 2022 American College of Chest Physicians guidelines on perioperative management of antithrombotic therapy as they are recognized as authoritative and widely used in clinical practice. Results: A clinical practice conceptual framework was adapted based on preexisting guidelines, dividing decision-making into 3 steps: (1) assessing the procedural bleeding risk; (2) assessing the patients' thromboembolic risk; and (3) determining appropriate management according to antithrombotic agent type. Specific indications are provided for continuing, stopping, and bridging anticoagulants and antiplatelet agents, as well as for consultation with a cardiologist or hematologist. Conclusion: The present framework can be implemented in plastic surgeons' clinical practice to guide the management of patients on antithrombotic therapies, while minimizing nonessential referrals to the thrombosis service. The lack of plastic surgery-specific guidelines on this topic highlights a need for further research to "bootstrap" the risk categorization of plastic surgical procedures and their appropriate perioperative management.
