Pulmonary embolism occurs when one of the pulmonary arteries in the lungs becomes blocked. Several medical studies found that
pregnant women are at greater risk of developing the condition. For most cases, pulmonary embolism develops in conjunction with deep vein thrombosis. This is known as venous thromboembolism.
There are three risk factors to consider: abnormal clotting, damage to the veins, and reduced blood flow. Pregnant women have increased potential because of the changes in hormones and blood composition. Pregnancy also reduces the amount of blood that flows in the legs due to the fetus’ weight. Obese women, those older than 35, or those who have a family or personal history of blood clots are considered at-risk patients.
Conditions for these women are carefully monitored during the first few weeks after delivery, where the risk of blood clots is at its peak. It must also be noted that delivery through caesarian section also increases the potential for developing pulmonary embolism. Blood clots can be prevented during pregnancy by wearing compression stockings or taking anticoagulant medicine.
Pregnant women diagnosed with either deep vein thrombosis or pulmonary embolism should discuss with both her OB-GYN and pulmonologist whether she should take an anticoagulant medicine during her pregnancy. One of the more recommended anticoagulants is heparin as it has been shown to have little to no effect on the fetus. Other anticoagulants may be taken after childbirth.
