Venous thromboembolism (VTE), deep vein thrombosis (DVT) and/or pulmonary embolism (PE) is a rare event in women of childbearing age, affecting 2–10/10,000 persons per year [1]. Exogenous sex steroids, mainly combined oral contraceptives (COCs) containing both synthetic oestrogen and progestogen, are slight transient risk factors for VTE [2]. They remain with pregnancy the most common risk factors in women of childbearing age [3]. Women who have their first VTE whilst taking oestrogens have a slight risk of recurrent VTE after stopping anticoagulation [4,5] and might not globally benefit from extended anticoagulant therapy.
