Pregnancy increases the risk of venous thromboembolism (VTE) due to physiological changes that cause a hypercoagulable state. The risk is highest in the first trimester and up to 6 weeks postpartum, and further increased with caesarean sections. VTE is a leading cause of maternal death in the UK. Risk factors include previous VTE, thrombophilia, immobility, and obesity. Thromboprophylaxis is recommended for high risk women. Diagnosis involves Doppler ultrasound or CT scan, and treatment involves low molecular weight heparin for 6 months. Amniotic fluid embolism and air embolism are rare but life-threatening complications of pregnancy
