When is restarting anticoagulation typically considered after surgery?

• A. Once hemostasis is achieved postoperatively
• B. Immediately during surgery
• C. Never restart
• D. After discharge only

Answer: (A)

Resuming anticoagulation after surgery is all about timing to balance bleeding risk with the risk of clotting. The safest approach is to restart once the surgical site has achieved hemostasis and is stable, because reinitiation too early can precipitate postoperative bleeding, while waiting too long leaves the patient vulnerable to thromboembolism.

Immediately during the operation would raise the chance of significant bleeding at the wound site, and never restarting anticoagulation ignores the ongoing thrombotic risk for someone who depends on anticoagulation. Restarting only after discharge can expose the patient to clots during the critical early postoperative period when the risk is highest. So, the usual practice is to resume once hemostasis is obtained and the surgical site is stable, with timing tailored to bleeding risk, the type of surgery, and the patient’s thrombotic risk.
