Reference values for fetal Doppler-based cardiocirculatory indices in monochorionic-diamniotic twin pregnancy

BMC Pregnancy and Childbirth, 2021
Background Placental anastomoses in monochorionic diamniotic (MCDA) twin pregnancy have a major impact on fetal circulation. This study was designed to define reference ranges of cardiac and vascular Doppler indices in MCDA twin pregnancies. Methods This

Implementation and Performance of First‐Trimester Referral Ultrasound Scan Following the Introduction of National Guidelines

Journal of Clinical Ultrasound, Volume 54, Issue 6, Page 1335-1348, July/August 2026.
The expert assessment of fetal anatomy before 14 weeks is feasible when adopting a standardized protocol and allows an early diagnosis in most cases at risk for fetal anomaly following first trimester screening ultrasound. ABSTRACT Background To report the implementation across Fetal Medicine units and the agreement between first and second trimester ...

Dopplervelocimetria no Rastreamento de Aneuploidias no Primeiro Trimestre da Gestação Doppler Velocimetry in Screening of Aneuploidy in the First Trimester of Gestation

Revista Brasileira de Ginecologia e Obstetrícia, 2001
Objetivo: estudar o valor da dopplervelocimetria do duto venoso, da artéria e da veia umbilical no rastreamento de anomalias cromossômicas entre a 10ª e a 14ª semana de gestação. Pacientes e Métodos: foram estudados 314 fetos consecutivamente.

Longitudinal reference ranges for ductus venosus flow velocities and waveform indices [PDF]

, 2006
OBJECTIVES: Serial Doppler measurements of the ductus venosus are used increasingly for monitoring fetuses at risk of hemodynamic compromise, but existing reference ranges are based on cross-sectional studies and thus are less suitable for comparison ...

Numerical Investigation of the Hemodynamics in the Human Fetal Umbilical Vein/ Ductus Venosus Bifurcation [PDF]

, 2012
The transport of oxygenated blood from the placenta to the human fetus has received great attention in clinical Doppler velocimetry studies, especially the ductus venosus. The ductus venosus is connecting the intra abdominal portion of the umbilical vein

Advancing fetal autopsy in cases of maceration: Underwater dissection technique and its forensic relevance

Journal of Forensic Sciences, Volume 71, Issue 4, Page 1821-1828, July 2026.
Abstract Fetal autopsy remains essential for determining the cause of intrauterine death and for supporting clinical, genetic, and forensic evaluations. However, in cases of advanced maceration, autolysis severely compromises tissue integrity, often preventing adequate identification of anatomical structures and limiting the diagnostic and medico‐legal

Spontaneous echocardiographic contrast due to ductus venosus

Türk Kardiyoloji Derneği Arşivi, 2017
Spontaneous echocardiographic contrast is defined as a phenomenon of discrete reflections appearing in the cardiac chambers or great vessels. It has been associated with several conditions leading to microbubble formation or low blood flow.

Prediction of neonatal acidosis by ductus venosus Doppler pattern in high risk pregnancies

Middle East Fertility Society Journal, 2013
Study objective: Evaluate whether ductus venosus (DV) Doppler velocimetry might be a good diagnostic tool of neonatal acidosis than umbilical artery (UA) and middle cerebral artery (MCA) blood velocities. Design: Prospective observational study. Setting:

Successful amnioinfusion for severe fetal growth restriction with umbilical cord complications: two case reports

Journal of Medical Case Reports, 2021
Background There is no established treatment for fetal growth restriction during pregnancy. We report two cases that represent an example of an amnioinfusion-based management strategy for severe fetal growth restriction with umbilical cord complications.
