A retrospective assessment of venous recanalization outcomes for oral anticoagulant treatment in deep vein thrombosis.

Abstract

This study aims to provide effective treatment by comparing the venous recanalization responses of oral anticoagulants in deep vein thrombosis therapy. From January 2013 to March 2019, a retrospective analysis was conducted on 109 patients who had been diagnosed with deep vein thrombosis and received treatment with apixaban, rivaroxaban, or warfarin within 1week of symptom onset. Demographic, clinical data, and venous recanalization responses on Doppler ultrasonography of the patients that were followed-up 1year from the date of diagnosis were evaluated. At the end of the 1-year follow-up, 21 (19.3%) patients had delayed recanalization, 39 (35.8%) patients had partial recanalization, and 49 (44.9%) patients had complete recanalization. The mean time to complete recanalization was 9.178 months for apixaban, 8.986 months for rivaroxaban, and 10.641 months for warfarin. Rivaroxaban was found to result in earlier completion of recanalization compared to warfarin (p = .012). Direct oral anticoagulants might be more effective than vitamin K antagonists in achieving complete recanalization in patients that have deep vein thrombosis. Improving outcomes can be achieved by evaluating current treatment options.
