What is the purpose of administering anticoagulants in women with CD during pregnancy?

Administering anticoagulants to women with certain medical conditions, like congenital heart disease (CD), during pregnancy primarily serves to prevent thrombophlebitis due to venous congestion. During pregnancy, the body undergoes significant changes, including increased blood volume and changes in blood flow dynamics. These changes can predispose pregnant women to thromboembolic events.

In women with congenital heart disease, the risk of venous thrombosis can be elevated due to impaired blood flow and an increased tendency for clotting, particularly in the lower extremities where stasis may occur. Anticoagulants help to reduce this risk by thinning the blood and improving circulation, thereby minimizing the chances of clots forming or venous obstruction occurring.

This intervention is crucial as thrombophlebitis can lead to more serious complications, such as pulmonary embolism, which poses a significant risk to both mother and fetus. Therefore, the administration of anticoagulants in these cases is a preventive measure aimed specifically at ensuring the safety and well-being of the mother during her pregnancy.
