Background: Direct oral anticoagulants (DOACs) are increasingly being used in the setting of venous thromboembolic disease (VTE). There is little evidence to guide the peri-procedural interruption of DOACs in this patient population. A number of studies have evaluated the perioperative interruption of DOACs based on half-life of the anticoagulant and the underlying procedural bleeding risk in patient with atrial fibrillation, but it remains unclear whether these findings can be extended to patients with VTE. Objective: Evaluate thrombotic and bleeding outcomes following the perioperative interruption of direct oral anticoagulation in patients with prior VTE. Methods: We conducted a retrospective analysis of consecutive patients on a DOAC for prior VTE requiring temporary interruption of anticoagulation for an invasive procedure. The primary efficacy outcome was the 30-day symptomatic VTE rate, and the primary safety outcome was the 30-day major bleeding rate. Secondary outcomes included overall mortality and the rate of clinically relevant non-major bleeding. Results: A total of 190 patients were included in the analysis. The 30-day VTE rate was 1.05% (95% CI, 0.29-3.8%) and the 30-day major bleeding rate was 0.53% (95% CI, 0.09-2.93%). There were no deaths during the 30-day follow-up period. The rate of clinically relevant non-major bleeding was 3.16% (95% CI, 1.46-6.72%). Conclusions: The perioperative interruption of DOACs in the setting of VTE, using a strategy that considers the half-life of the DOAC and the underlying procedural bleeding risk, appears to be both safe and effective.
