Pregnancy increases venous thrombosis risk by 4-5 times

Pregnant women face a 4 to 5 times higher risk of venous thrombosis compared to non-pregnant women, with the highest risk occurring during the postpartum period. This information was presented by Dr. Tao Tuan Kiet, Head of Anesthesia and Resuscitation at Tu Du Hospital, during a medical conference.

Statistics from Tu Du Hospital indicate that while venous thrombosis or pulmonary embolism accounted for approximately 3% of patients prior to surgery between 2019 and 2022, there has been an increase in detected cases among obstetric and gynecological patients from 2023 to 2025.

Risk factors for developing blood clots include undergoing surgery, prolonged immobility, advanced age, obesity, or underlying medical conditions. If a blood clot travels to the lungs, it can cause a pulmonary embolism, leading to circulatory failure, cardiac arrest, or death. Medical professionals emphasize the need for proactive risk assessment and prevention during maternal care.
