Description
Summary:	To study two women who presented with internal jugular vein thrombosis that developed shortly after in vitro fertilization (IVF) therapy complicated by mild ovarian hyperstimulation syndrome (OHSS). Evaluation of the past medical history, treatment, laboratory studies, and clinical outcome of both patients. The two patients were found to be carriers for factor V Leiden mutation (FVLM). One was homozygote and the other heterozygote for that mutation. The genetic predisposition probably contributed to the development of an early thrombosis in these patients despite the mildness of their OHSS. In the homozygote patient, the dose of low molecular weight heparin was reduced due to vaginal bleeding. Afterwards, fetal loss due to an extensive placental infarction occurred. Infarction was confined to maternal side while the fetal side vessels were spared. We suggest that women of European descent, especially those with personal or familial history of thromboembolic events, should be screened for FVLM before IVF treatment. In those found to be carriers of FVLM, preventive anticoagulation should be considered.
