IVF Increases The The Risk Of Thrombosis

IVF Increases The The Risk Of Thrombosis.
Women who became in a family way through in vitro fertilization (IVF) may have an increased hazard of developing blood clots and potentially devastating artery blockage, Swedish investigators suggest. Although the risk remains small, the discrepancy are especially high during the first trimester compared to women who become pregnant naturally, the researchers said. Blood clots - called venous thromboembolism - can demonstrate in the leg veins and intervene free, traveling to the lungs and blocking a main artery. This condition, called pulmonary embolism, can cause hindrance breathing and even death.

So "There is an increased incidence of pulmonary embolism and venous thrombosis amidst women pregnant after IVF," said lead researcher Dr Peter Henriksson, a professor of internal c physic at the Karolinska Institute in Stockholm. "Embolism is the leading cause of devoted mortality during pregnancy. The diagnosis can be elusive, so physicians should be aware of this risk to facilitate the diagnosis".

The jeopardize of clotting during pregnancy isn't confined to women who undergo IVF, another experts said. "Any pregnancy carries a jeopardy of clotting," said Dr Avner Hershlag, principal of the Center for Human Reproduction at North Shore University Hospital in Manhasset, NY. This is because hormones, principally estrogen, increase during pregnancy. "This changes what we call the clotting cascade. There are many factors in blood clotting that can be distressed by hormones - especially estrogen".

In addition, the enlarging uterus puts intimidation on pelvic blood vessels, which can lead to clotting. Some women are advised to guide their movement to reduce the risk of clotting. Although it's unclear why women who stand IVF have a greater risk of clotting, Hershlag speculates that it could be due to fertility treatments that further estrogen even beyond levels normally associated with pregnancy.
