Obstetric venous thromboembolism: Evaluation of prophylactic approach based on risk scores, D-dimer levels, and ultrasonography findings in a tertiary hospital in Japan.

Aim: Pulmonary embolism remains a leading cause of maternal mortality in developed countries despite developments in venous thromboembolism prophylaxis strategies. This study aimed to evaluate the effectiveness of our approach involving risk-scoring, D-dimer level assessment, and ultrasonography for obstetric venous thromboembolism.

Methods: This retrospective cohort study included women who delivered at 22-41 weeks of gestation in The University of Tsukuba Hospital, Japan between January and December 2020.

Higher D-dimer level in the early third trimester predicts the occurrence of postpartum hemorrhage.

Aims: This study aimed to determine effective predictive factors for primary postpartum hemorrhage (PPH) among clinical blood parameters associated with coagulation and fibrinolysis and demographic characteristics.

Methods: We retrospectively studied 1032 women who underwent determinations of clinical blood parameters at gestational week (GW) 29-32 and GW 35-37 and gave birth to singleton infants at our hospital between January 2011 and December 2013. PPH was defined as estimated blood loss ≥700 mL.
