Placental chorioangioma is a non-trophoblastic benign tumor of rare presentation. It may be associated with complications of pregnancy when larger than 4 cm. We present the case of a pregnant adolescent with 25 weeks of gestation referred for prenatal management of a giant placental chorangioma that complicated pregnancy with hydramnios and severe fetal anemia. Fetoscopic laser ablation of the main nutrient vessel of the tumor was performed for the first time in Peru, which reversed complications and improved fetal prognosis.

Objective. To determine the similarity or difference in femur length of normal fetuses compared to fetuses with Downsyndrome at the Maternal Perinatal Institute period 2011-2015. Methodology. It is a quantitative, retrospective, observational,descriptive and cross-sectional descriptive study. Our population was all fetuses of the National Perinatal Maternal Institutein the period 2011-2015, which had the measure of Femur Length and the complete database, which meet the criteria ofInclusion and Exclusion.

A case of a pregnant woman referred to our center at 27 weeks of gestational age for twin reversed arterial perfusion (TRAP) sequence is reported. Fetoscopy and bipolar coagulation of the umbilical cord of the acardiac twin was performed with successful outcome.

Pfeiffer syndrome is an autosomic dominant disorder characterized by craniosynostosis, midface hypoplasia and syndactyly of the hands and feet. Three different phenotypes have been described, where type 2 is the most severe and the one amenable of prenatal diagnosis. We present the first clinical case reported at Instituto Nacional Materno Perinatal, Lima, Peru, of a fetus with suspicious ultrasound prenatal findings of this syndrome including cloverleaf-shaped skull, severe ventriculomegaly, frontal bossing, ocular proptosis and overlapped fingers, who was born by cesarean section and died at day eight due to progressive respiratory distress.

Multicystic renal dysplasia is a rare and little know in our country. The aim of this paper is to present and critically discuss the diagnosis, assessment and perinatal outcome of a case of multicystic dysplastic kidney and its differential diagnosis.

Objectives: Set the values for reference index pulsatilidad of artery uterine between 11-41 weeks of gestation in fetuses healthyin the maternal perinatal national institute in the period 2010 to 2016. Desing: Retrospective Cross-sectional descriptive study.Participants: Healthy fetuses. Main outcome measures: Reference ranges of the uterine artery pulsatility index.

Objective: To establish reference values of pulsatility index of the middle cerebral artery in healthy fetuses. Method: This is adescriptive, retrospective and cross-sectional study conducted at the National Maternal Perinatal Institute between 2014 and 2016.1865 women with a single pregnancy and low risk were registered between 20 and 40 weeks of gestation and were screened DopplerFetal middle cerebral artery.

Objective. To know the indicators of placental insufficiency in term and post - term gestation with normal fetal growth and adverse outcome in the National Maternal Perinatal Institute during the year 2017. Materials and methods. A correlational, descriptive, cross-sectional and retrospective study was performed in 37-42 weeks' pregnant women with normal umbilical Doppler and normal fetal growth. We investigated the association between eight indicators and six adverse outcomes for placental insufficiency.

Existen entidades internacionales líderes y referentes en evaluación fetal que discrepan en los valores de referencia Doppler usados para Arteria Umbilical.

Las bajas tasas de detección de restricción de crecimiento intrauterino (RCIU) se explican en parte porque no hay un consenso en anteponer la edad gestacional real en el informe ecográfico. Muy pocos lo hacen y la mayoría sólo informa dando una edad por el promedio biométrico. Tampoco es rutina determinar e informar el percentil del peso estimado fetal.

Objectives. To determinate the risk of death in new-boros with diagnosis of Selective intrauterine growth restriction in twin pregnancy according sex. Material and methods. Analytic, cross sectional and retrospective. The sample of new-boms with diagnosis of selective intrauterine growth restriction (SIUGR) was selected in the period between February 21'h, 2011 and November 241', 2014 on the National Maternal Perinatal Institute where were included 60491 new-boros, of which 58629 corresponded to single pregnancies, 1790 to twin pregnancies (683 new-borns with SIUGR; 335 of feminine sex and 348 of masculine sex) and 72 to triple pregnancies.
