RESUMO
Pregnancy complications are still a challenge for physicians, because knowledge of pathomechanisms and prophylactic measures is still limited. In recent years thrombophilia as a risk factor for pregnancy complications has gained much attention in the scientific community. To study the rate of thrombophillia gene in cases with recurrent abortion. In the period between January 2006 and May 2007, 40 consecutive patients with a history of recurrent failed IVF and abortion, defined as fetal loss before 16 weeks' gestational age, were screened by the following tests: Molecular diagnosis of 11 thromobophilia gene mutation, ACL IgG and IgM. PtC, PtS. ATIII and Lupus anticoagulants. 40 patients were included in this study and the following data was recorded: All cases were negative to protein C, S and anti T Ill. One case showed positive anti cardiolipin Ig M-3 cases positive for Lupus anticoagulant, all the cases were positive for multiple thrombophillia genes. The observed rate of successful pregnancies of women treated with aspirin, who had mild thrombophilia and a history of a single abortion, is much lower than it would haye been expected from patient treated with combined therapy
