BACKGROUND: The long-term recurrence risk after a pregnancy-associated venous thromboembolism (VTE) is sparsely assessed.
OBJECTIVES: To determine the rate of recurrence after a pregnancy-associated VTE and identify associated risk factors.
METHODS: Five hundred eighty-seven women with a history of first VTE occurring during pregnancy or up to 3 months after delivery were referred to La Timone Hospital, Marseille, France. Women were consecutively included between 2000 and 2015. VTE characteristics and biological parameters were collected upon inclusion. During the 2016-2019 period, patients were recontacted to gather information on postinclusion VTE. A weighted Cox model, adapted to the study's ambispective design, was used to analyze pre- and postinclusion VTE recurrences.
RESULTS: After quality controls, 583 women were analyzed. The incidence of recurrent VTE was 2.4% person-years. The cumulative risk of VTE recurrence was 38% (n = 221), with a median follow-up of 31 years (95% CI: 27-35); 6%, 13%, 17%, and 30% at 2, 5, 10, and 30 years respectively. Pulmonary embolism at first event was associated with a 2-fold increased risk of pulmonary embolism at recurrence compared with isolated deep venous thrombosis (DVT, hazard ratio [HR]: 2.63; 95% CI: 1.44-4.82). Risk factors significantly associated with recurrence were interrupted pregnancies (HR: 1.85; 95% CI: 1.18-2.90), lower limb DVT (HR: 2.95; 95% CI: 1.16-7.49), and AB blood group (HR: 1.71; 95% CI: 1.06-2.77).
CONCLUSION: Although the recurrence risk is low within the first 10 years after a pregnancy-associated VTE, one-third of patients experienced a new event over a 30-year period. Interrupted pregnancies, lower limb DVT, and AB blood group were associated with higher risk of recurrence.
