There pre-eclampsia (PE) complicated between 2 And 7% of the pregnancies (WHO 2005), It is a cause major of mortality And of morbidity kindergarten And perinatal. The benefit of uterine Dopplers (DU) in the first trimester has been demonstrated as factors predictive of there PE (in particular among THE pathologies vascular placental (PVP) ), notably the value of the index of pulsatility (IP). Thanks to the measurement of the pulsatility index, medical and family history of the patients, of there pressure arterial average And of some markers b iochemicals, it is today possible to establish from the first trimester a calculation of the risk of development of PVP For a patient at course of her pregnancy. This screening early allow to identify THE women has risks And will allow soon to be able to introduce preventive treatment and thus reduce the rate of occurrence of these pathologies. The uterine Doppler constitutes one of the key parameters of this screening. It therefore appears essential that his realization either there more reliable possible. Its measurement can be done, with ultrasound machines, abdominally and, when this is impossible to carry out, the measurement can be done endovaginally. HAS To our knowledge, there is only one study comparing the two approaches (Plasencia et al). The main objective is to know if he there is a difference between uterine dopplers obtained by the abdominal route and those obtained by the endovaginal route . If there is a difference it would be relevant to find a corrective factor allowing the integration of the IP measure by endovaginal route calculation risk of EP. The objective secondary East of compare there quality of the dopplers uterines according to there way First of all used And to assess the possible impact of BMI on r there quality of these dopplers. Firstly, we will present current knowledge concerning the performing the uterine Doppler, then we will present the method and results of the study conducted, And Finally, We we will discuss these results And We THE will
