Superficial Thrombophlebitis of Great Saphenous Vein Following Vaccine

Abstract

This paper reports on the occurrence of thrombose of the left great saphenous vein (GSV) soon after being given the AstraZeneca vaccine and two recurrent events within three days after the suspension of the anticoagulant. A 53-year-old patient had superficial thrombophlebitis of the GSV in the left leg three days after taking the second dose of the AstraZeneca vaccine for COVID-19 and initiated treatment with rivaroxaban (XareltoTM) 15 mg twice a day, subsequently increasing to 20 mg. After 45 days, the patient contracted dengue and stopped taking the anticoagulant. Two days later, the patient had another thrombosis in the left GSV. The patient is currently in outpatient care with a prophylactic dose of 10mg/day of anticoagulant and undergoes evaluations at three-month intervals. The result of our study is a rare event.
