Applicability of Fetal Doppler Ultrasound to Identify Alterations Suggestive of Extra-Cardiac Anomalies (First Part)

Abstract

Introduction: Fetal Doppler ultrasound is the method of choice to identify alterations that put the fetus at risk;this tool has revolutionized the traditional conception of Perinatology as it gives the opportunity to understand that the pathophysiological process of the sick fetus presents a hemodynamic deterioration. Objective: To describe the applicability of fetal Doppler ultrasound in the main extra cardiac anomalies. Methods: Bibliographic review of scientific articles published in Spanish and English and their corresponding validation under CASPe and PRISMA tools. Results: A bibliographic analysis of 92 citations was carried out under the aforementioned systematic search in which the main fetal anomalies were separated under the supradiaphragmatic, infradiaphragmatic and cerebral concept. Conclusion: There are a limited literature regarding Doppler ultrasound evaluation in relation to extra-cardiac anomalies,and among them there are discrepancies in the findings found between various authors.
