Pregnant women are at higher risk of venous thromboembolism after in vitro fertilisation, particularly during the first trimester.
The risk of pulmonary embolism in women after in vitro fertilisation was increased almost sevenfold during the first trimester, although the absolute risk was low (two to three additional cases of pulmonary embolism per 10,000 pregnancies).
Pulmonary embolism is, however, an elusive condition that is difficult to diagnose and is a leading cause of maternal death. Our finding is therefore important to health professionals dealing with women who are recently pregnant after in vitro fertilisation.Doctors should be aware of these increased risks because the symptoms of pulmonary embolism can be insidious and the condition is potentially fatal.
Women who undergo IVF have a higher risk of experiencing blood clots while they are pregnant, a new study has found.
Swedish researchers found that a higher ratio of women who got pregnant following in vitro fertilisation (IVF) suffered from venous thromboembolism (blood clots) than those who became pregnant naturally.
The risk of pulmonary embolism - a potentially fatal blood clot which can prevent blood from reaching the lungs - in women who had the fertility treatment increased almost seve-nfold during the first trimester of pregnancy, according to the research.
