Abstract
In vitro fertilization (IVF) procedures have been frequently associated with antithrombotic treatment, particularly aspirin or low molecular weight heparin. Historically, this type of treatment has been intended to increase the success rate of IVF with embryo transfer (IVF-ET) and live births after the procedure, as well as to prevent thrombotic disorders during pharmacological ovarian stimulation. Recurrent IVF failures and venous thromboembolism (VTE) complications during IVF-ET may be related to inherited thrombophilia. However, there aren't many studies in the literature on the frequency of VTE or bleeding in women undergoing thromboprophylaxis for IVF-ET, and reports on the caliber of clinical data vary. Thus, in this report, we describe our clinical experience with early antithrombotic prophylaxis with enoxaparin in women who have had thrombophilic defects and are undergoing IVF-ET over a period of years.
