The aim of this guideline is to provide advice, based on clinical evidence where available, regarding the prevention of venous thromboembolism (VTE) during pregnancy, birth and following delivery. For the diagnosis and management of acute VTE in pregnancy, please refer to Green-top Guideline No. 37b: Thrombosis and Embolism during Pregnancy and the Puerperium: Acute Management.
For anticoagulation for mechanical heart valves in pregnancy, read the chapter covering this within the proceedings of the RCOG study group on heart disease - a summary of the guideline for antenatal and postnatal thromboprophylaxis is given in Appendix I.
Erratum: correction made to the Transient risk factors in Appendix III to link dehydration with hyperemesis not immobility.
