Initiate warfarin and titrate dosage to achieve an INR of 2 to 3; continuefor the full term of the pregnancy.C. The use of serial ultrasonography studies during early pregnancy have shown that the arterial signals in the yolk circulation disappear and the umbilicoplacental circulation increases between 8 and 10 weeks of gestation, indicating that the placenta replaces the yolk sac as an essential source of blood supply to the embryo at that time.1 Thus, it can be deduced that during the switch and at least from the beginning of the 11th week of gestation the maintenance of the permeability of the maternal placental intervillous space becomes a crucial necessity for the viability of the fetus.

This is known as deep vein thrombosis (DVT), which most commonly occurs in the legs. Objective: The aim of this study was to compare the effects of low molecular weight heparin (LMWH), LMWH plus low dose aspirin, or low dose aspirin only on pregnancy outcomes in recurrent pregnancy loss (RPL) patients with factor V Leiden mutation (FVLM).Materials and methods: A total of 2764 RPL patients were evaluated in for the etiology of RPL. In patients taking aspirin, losses occurred between the 11th and the 18th week of amenorrhea (median, 15; lower and upper quartiles, 13 and 16). In patients taking enoxaparin, losses occurred later on: from the 17th to the 24th week (during weeks 23 and 24 in 2 patients). The site is secure. Fetal complications such as miscarriage,7 intrauterine fetal demise (IUFD), placental abruption, and intrauterine growth retardation (IUGR)1 have also been associated with FVL.
