Recurrent fetal loss (RFL) is a significant clinical problem, occurring in 1% to 5% of reproductive females. Inherited or acquired thrombophilia has been diagnosed in 50% to 65% of women with history of unexplained fetal loss. The objective of our study was to determine the prevalence of thrombophilia in women ...
Santoro Rita - - 2009
Pregnancy is associated with an increased risk of venous thromboembolism, which probably varies according to the presence of single or multiple thrombophilic defects. Acquired or inherited thrombophilia is moreover associated with adverse outcomes in pregnancy. For this reason, in the past, pregnant women at risk of venous thromboembolism or pregnancyes ...

Pregnancy is associated with an increased risk of venous thromboembolism (VTE) and approximately half of all pregnancy-related VTEs are associated with thrombophilia. Recent studies suggest that there is a link between thrombophilia and other adverse pregnancy outcomes, such as fetal loss, preeclampsia, placental abruption and intrauterine growth restriction. However, the ...

Pregnancy is associated with a fivefold increase in the prevalence of venous thromboembolism, and pulmonary embolism is a leading cause of maternal death. However, the diagnosis of pulmonary embolism during pregnancy is challenging because classic clinical symptoms are often absent and physiologic changes during pregnancy can mimic pulmonary embolism. Concerns ...

Venous thromboembolism is a major cause of maternal morbidity and mortality, and accurate diagnostic workup upon suspicion of deep vein thrombosis or pulmonary embolism in a pregnant woman is of utmost importance. The diagnostic repertoire for venous thromboembolism is, however, less well studied in pregnant women. The clinical assessment is ...
Hvas Anne-Mette - - 2009
Pregnancy in healthy women is accompanied by hypercoagulable changes that may interact with thrombophilia risk factors and threaten pregnancy. However, the literature on this issue is conflicting. In investigating the relationship between pregnancy-associated complications and the presence of thrombophilia risk factors, we studied the records of 414 women who had ...
Pabinger Ingrid - - 2009
In recent years thrombophilia has gained much attention as a risk factor for pregnancy complications. Whereas there is an established correlation between antiphospholipid antibodies and pregnancy loss, data for other risk factors of thrombosis are less well established. Data suggest associations with antithrombin deficiency, hyperhomocysteinemia and also with factor V ...
Sood Rashmi - - 2009
Inherited thrombophilia is recognized as one of the causes of recurrent fetal loss. Yet, the risk of fetal loss in women with thrombophilia is far from absolute. Other risk modifiers are clearly involved, but remain to be identified. The mechanism that translates maternal thrombophilia into pregnancy disorder is also not ...
Goodman Chelsi - - 2009
PROBLEM: We have previously reported the role of polymorphisms of thrombogenic genes involved in coagulation and fibrinolysis as risk factors for recurrent pregnancy loss. Thrombophilia has been viewed as a multigenic disorder rather than a monogenetic clinical phenotype and Apo E has been shown to play an important role in ...

Pregnancy in women with mechanical valve prostheses has a high maternal complication rate including valve thrombosis and death. Coumarin derivatives are relatively safe for the mother with a lower incidence of valve thrombosis than un-fractionated and low-molecular-weight heparin, but carry the risk of embryopathy, which is probably dose-dependent. The different ...
