Context: Hormone-dependent gynaecological disorders, such as polycystic ovary syndrome (PCOS) or endometriosis, have been recently discussed as potential risk factors for venous thromboembolism (VTE). Combined hormonal contraceptive (CHC) therapy, which is a well-known risk factor for VTE, is usually used to alleviate symptoms related to these gynaecological disorders. Nevertheless, prevalence of hormone-dependent gynaecological disorders at the time of VTE event and the management of hormonal contraceptives are not well known., Objective: To assess retrospectively the prevalence of hormone-dependent gynaecological disorders in patients with VTE event and the hormonal therapy at the time of VTE event and at the time of inclusion in the present study., Methods: Women aged between 18 to 50-year-old who were hospitalized at Saint-Joseph Hospital (Paris) for a VTE event from January 1st, 2016 to December 31st, 2020 were included in this retrospective observational study., Results: In total, 125 women were included. At the time of VTE event, mean age was 39-years-old (±8) and mean body mass index (BMI) 26kg/m 2 (±8). Pulmonary embolism represented more than two third (68%) of VTE events. Fourteen women (11%) had PCOS and among them, 6 (43%) were using CHC. Eleven women (9%) had endometriosis and among them, 1 (9%) was using CHC. Women with PCOS appeared to be younger at the time of VTE compared to non-PCOS women (mean age 32 years (±6.0) vs. 40 years (±8.0), respectively, P<0.001), whereas women with endometriosis were older with a mean age of 43-year-old (±7.8), which did not differ significantly from women without endometriosis. Among PCOS women, 1 (7%) VTE event was idiopathic, whereas among those with endometriosis, 5 (46%) VTE events were idiopathic. Regarding contraceptive use at the time of inclusion, with a mean delay between VTE event and inclusion of 3 years (±1), 1 woman pursued CHC, 35 (28%) used non-hormonal contraceptive. Seventy-three women (58%) were aware of hormonal contraindications due to VTE event., Conclusion: The present study, including 125 young women with a mean age of 39 years, allowed a description of gynecological pathologies and history of contraceptive use potentially involved in VTE events., (Copyright © 2022 Elsevier Masson SAS.
