Ultrasound evaluation of fetal central nervous system anomalies and its correlation with postnatal outcome

International Journal of Medical Research and Review, 2017

Introduction: CNS anomalies are the most serious congenital abnormalities. Ultrasound is an effective and non invasive modality of prenatal diagnosis of these anomalies. The purpose of the current study was to determine the frequency of CNS anomalies and its postnatal outcome. Objectives: Present study was undertaken to find out the incidence of CNS anomalies in utero by ultrasound and to confirm them by autopsy or postnatal examination. Materials and Methods: Ultrasound scanning of 5761 pregnant w omen was performed. Pregnancies with ultrasound findings of CNS anomalies were followed up. Prenatal findings were compared with postnatal findings and confirmed by autopsy wherever possible. In case of live birth post natal findings were noted. Results: Ultrasound detected 50 anomalies in 42 cases. Ultrasound findings were exactly matching in 90%. 4 cases had variations 3 on autopsy & 1 on postnatal USG. Conclusion: The incidence of CNS malformations on ultrasound was 0.73%. Autopsy and postnatal findings showed high degree of correlation with prenatal ultrasound findings.

Comparison of prenatal ultrasound and postmortem findings in fetuses and infants with central nervous system anomalies

Ultrasound in Obstetrics and Gynecology, 1998

Detection of fetal developmental abnormalities by ultrasound examination of pregnant women has become a specialized field of medicine. Quality control of this field requires detailed examination of aborted fetuses. In 408 fetuses and infants with developmental anomalies, the prenatal ultrasound findings were compared with the postmortem findings. This study focused on 140 central nervous system (CNS) anomalies. Criteria for inclusion were an ultrasound examination at the National Center for Fetal Medicine (NCFM) and an autopsy performed during the period 1985-94. Results of the ultrasound and autopsy examinations were systematized into six different categories.

Results: CNS anomalies were the most common congenital anomalies observed. Out of the total 50 stillborn fetuses studied, CNS anomalies were found in 17 fetuses and their occurrence was more common among male stillborn than females...

Congenital Central Nervous System and Associated Systemic Anomalies in Foetal and Perinatal Autopsy- A Retrospective Study

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH

Introduction: Congenital malformations in India accounts for 10-15% of perinatal deaths. Congenital Heart Defects (CHD) is most common congenital anomaly followed by Central Nervous System (CNS) anomalies, among which Neural Tube Defects (NTD) are most common. Folic acid deficiency can lead to NTDs and can be corrected by its supplementation in subsequent pregnancies, the authors analysed neurological anomalies in foetal and perinatal autopsies to ascertain distribution of various congenital neurological malformations and to classify those according to WHO classification system and their association with other systemic malformation. Aim: To study CNS anomalies in foetal autopsies. Materials and Methods: The present retrospective study conducted in Department of Pathology, Karnataka Institute of Medical Sciences, Hubli, Karnataka, India from July 2015 to June 2020 analysed 500 foetal autopsies retrospectively. Data regarding maternal age, parity, history of previous abortion, foetal ...

Perinatal Autopsy: A 3 year Study of Central Nervous System Anomalies.

IOSR Journals , 2019

Background: CNS anomalies are due to defective closure of neural tube.It is associated with other systemic anomalies in most of the cases. This study was undertaken to determine the incidence of CNS anomalies among congenital malformations at autopsy, associated systemic anomalies, maternal age and sex of the fetus. Objectives: To determine the incidence of central nervous system anomalies among congenital malformations at perinatal autopsy. Methods: The present study comprises 62 consecutive perinatal autopsies conducted after obtaining consent from the parents/guardians. In cases where prenatal ultrasound findings were available they were compared with the autopsy findings. Results: Out of 62 perinatal autopsies, 27 cases showed congenital anomalies with M:F = 1.2:1. The malformations involving the central nervous system were commonest, seen in 9 cases (33.3%). Anencephaly is the most common type of anomaly seen in 6(66.6.%) cases. Conclusion: This study highlights the importance of perinatal autopsy in confirming the diagnosis of congenital anomalies by prenatal ultrasound findings. Pathological examination of the fetus is essential to document associated anomalies.

Study of Congenital Neurological Anomalies in Foetus

Congenital defects and anomalies present at birth have induced curiosity in people, since the dawn of history. In early societies, the babies surviving with developmental defects were considered as Monsters and were thought to be a curse on the mother or family. Prehistoric period reveals the records of human congenital malformations in cave paintings, sculptures and in writings. Archeologists have found skeletons of malformed infants dating as far back as the Stone Age. In the dark middle ages, mothers were burnt for the alleged curse of giving birth to a malformed child. The present study was done on 50 still born and aborted fetus around age group of 26 weeks to 40 weeks obtained from Gandhi Hospital Secunderabad,6 of them had central nervous system abnormalities of anencephaly to spina bifida,1case of meningocele. The author found a high incidence of central nervous system anomalies which suggest that they may be due to nutritional defiencies like folic acid and vitamin B 12 as the present study involved people from rural areas around Hyderabad and Secunderabad in a low socio economic group.

Autopsy Findings of Central Nervous System Anomalies in Intact Fetuses Following Termination of Pregnancy After Prenatal Ultrasound Diagnosis

Pediatric and Developmental Pathology

Objectives Central nervous system (CNS) anomalies are the second most frequent category of congenital anomalies after congenital heart defects (CHDs). In this study, the aim was to investigate the distribution of different CNS anomalies with associated anomalies and karyotype in a fetal autopsy population of terminated pregnancies over a 30-year period and to correlate the ultrasonographic diagnoses of CNS anomalies with autopsy findings. Materials and Methods This study includes 420 intact fetuses with CNS anomalies terminated at gestational ages 11+ 0 to 33+ 6 over a 30-year period from 1985 to 2014.

Study of Foetal Ultrasound of Neuroectodermal Anomalies in Antenatal Mothers

International Journal of Medical and Biomedical Studies, 2019

This study was to evaluate the incidence, prevalence and various types of neuroectodermal anomalies of foetuses in antenatal mothers. Methods: All pregnant women with intrauterine pregnancy of gestational age ranging from 12 weeks to Post-term cases were included for this study. We were studied on 21450 ultrasound scan of antenatal mothers, who were come for routine check up. Among them 50 foetuses anomalies were found. Results: Data was analyzed by using simple statistical methods with the help of MS-office software. All data was tabulated, and percentage was calculated. Conclusions: Neuroectodrmal anomalies of foetuses were commonly seen in maternal age group of 30-40 years and prevalence was 0.23%. Anencephaly and hydrocephalus associated with spina bifida were seen in most of the CNS anomalies foetuses. Spina bifida in the lower lumbar region associated with a meningocoele or myelomeningocoele was the most common. Hence, ultrasound is an effective investigative modality for in utero screening of congenital anomalies. Ultrasound imaging in antenatal period practically gives an anatomical record of the developing foetus. So that early detection of anomalies especially in first and early second trimester helps in planning termination, interventions and further management of neuroectodermal anomalies foetus.
