Introducción: Los trastornos hipertensivos son una de las complicaciones médicas más frecuentes que se producen durante el embarazo, constituyendo un problema de salud pública en todo el mundo. En el Perú se registra entre un 7% y 9% y su importancia radica en que constituye una de las tres primeras causas de mortalidad materna y de restricción del crecimiento intrauterino. En los últimos años, se ha demostrado que un patrón anormal en las ondas velocidad de flujo de las arterias uterinas durante el primer y segundo trimestre del embarazo está relacionado con un mayor riesgo de desarrollar preeclampsia. Objetivo: Determinar el valor predictivo del índice de pulsatilidad (IP) promedio de las arterias uterinas para el punto de corte mayor o igual al percentil 95 (≥ P95) en la detección precoz de preeclampsia en las gestantes entre 11 y 14 semanas que acudieron a la Unidad de ...

Objective. To determine the uterine artery mean pulsatility index and to calculate the predictive value of the uterine artery mean pulsatility index ≥ 95th centile to predict Preeclampsia in pregnant women between 11 y 14 weeks. Lugar. Fetal Medicine Unit at INMP, a teaching Hospital, between May 2009 to March 2010. Materials and methods. Participants. Pregnant women between 11 y 14 weeks.Interventions. Uterine artery Doppler was carried out at 11 y 14 weeks in pregnant women attending for routine antenatal care. The right and left uterine arteries were identified using color flow mapping and velocity waveforms were obtained using pulsed Doppler. Main outcome measures. Determination of the uterine artery mean pulsatility index, identification of ≥ 95th centile, determination of sensibility, specificity, positive and negative predictive value. Results. Of 120 patients enrolled, 24 dev...
