OBJECTIVE
Holoprosencephaly is a kind of brain anomaly characterized by inadequate cleavage of the prosencephalon during early embryogenesis. In addition, holoprosencephaly associated with cystic hygroma and hydrops fetalis has never been reported. In this article, we report a rare case of
Fourteen cases of holoprosencephaly (HP), including 10 cases of alobar HP and four cases of semilobar HP, were identified by prenatal sonography. Intracranial and extracranial findings were reviewed to determine the accuracy and spectrum of the sonographic features. All 14 cases were reliably
Holoprosencephaly is one of the rare types of craniofacial congenital anomaly characterized by failure of differentiation of the procencephalon to diencephalon and telencephalon derivatives that accompanied by variable degree of orbitofacial dysmorphism. The case presented to our hospital in the
OBJECTIVE
To present perinatal detection of distal 3p duplication and terminal 7q deletion associated with nuchal edema and cyclopia in a fetus, and to review the literature.
METHODS
A 32-year-old, G9P0, woman who had experienced eight spontaneous abortions was found to have fetal nuchal edema,
Although rare, a number of fetal anomalies can be detected with ultrasound in which the prognosis is either fetal death or minimal development. Anomalies of this type include anencephaly, holoprosencephaly, hydranencephaly, iniencephaly, cystic hygroma with hydrops, cystadenomatoid malformation of
OBJECTIVE
To establish the prevalence of congenital malformations diagnosed in Maternal-Fetal Medicine Unit of Hospital de San José, Bogotá-Colombia and comparing them to national and international reports.
METHODS
Retrospective, descriptive observational where the quantification of all malformed
A 5-year prospective prenatal study in 151 pregnancies with 152 malformed fetuses detected by ultrasound was evaluated cytogenetically. Thirty-five fetuses (23%) had abnormal karyotypes. Specific anatomical fetal malformations identified by ultrasound increase the risk for fetal chromosome
OBJECTIVE
To determine the sensitivity of first-trimester ultrasound for diagnosing different structural anomalies in chromosomally normal pregnancies, and to establish the role of aneuploidy markers in the detection of abnormalities.
METHODS
This was a retrospective study of chromosomally normal
Fetal neurologic consultations were provided to 166 maternal-fetal pairs over a 5-year period. Consultations were initiated during the second trimester in 46% (74/166) of pairs. Fifty-percent (83/166) of these consultations involved brain malformations, of which 55% (46/83) were also associated with
OBJECTIVE
To determine the association between some major structural abnormalities detected prenatally by ultrasound and chromosomal abnormalities.
METHODS
The present study was a retrolective, transversal study. We analyzed case records of patients during the fetal follow-up at the Department of
OBJECTIVE
To report five cases of major congenital malformations associated with common aneuploidies detected by rapid aneuploidy diagnosis.
METHODS
The fetus in the first case presented cebocephaly, semilobar holoprosencephaly, and tetralogy of Fallot on ultrasound at 25 gestational weeks.
BACKGROUND
This study investigated the survival and natural history of trisomy 13 in a series of patients, comparing the management and outcome before and after the implementation of Taiwan's National Health Insurance program (NHI).
METHODS
A total of 28 cases of trisomy 13 seen at Mackay Memorial
Over a 3 year period 37 pregnancies were complicated by a chromosomal abnormality. In the two cases of trisomy 13, holoprosencephaly, facial clefting, polydactyly and growth retardation were seen. In the seven cases of trisomy 18, abnormalities of the extremities, face and heart were common. Growth
OBJECTIVE
The purpose of this study was to evaluate the diagnostic utility of karyotype analysis of amniotic fluid for fetuses with abnormal sonographic findings and to determine the detection rates of abnormal karyotypes.
METHODS
We conducted a retrospective study of 5328 fetuses with abnormal
