TIn the US, one in 1000 births is affected by neural tube [4] defects (NTD). A neural tube [4] defect is a birth defect involving the malformation of body features associated with the brain and spinal cord. An NTD originates from and is characterized by incomplete closure of the neural tube [4], which is an organizer [5] and precursor of the central nervous system [6]. In humans [7], incomplete...

During a prospective study of 3500 consecutive births from November 1985 to January 1987 at three hospitals, 40 babies were found to have neural tube defects, an extremely high incidence (11.4/1000 births). The defects comprised anencephaly (n = 18), meningomyelocele (n = 11), Arnold-Chiari deformity (n = 3), encephalocele (n = 3), iniencephaly (n = 2), and one each of occipital meningocele, sp...

Fetal neck is the site of important pathological changes, related to genetic, cardiovascular, lymphatic, endocrine systems. Among the main neck pathology are fetal hygroma, goiter, teratoma/sarcoma, hemangioma/lymphangioma. Posterior anomalies of the fetal neural tube, such as occipital myelomeningocele or iniencephaly may also be included in this area. Fetal hygroma is the main pathology, prob...

The neural tube defects (NTD) are a group of congenital malformations which are depressingly familiar to many obstetricians in the UK. Despite intensive investigation, their basic aetiology remains unknown. It seems probable that genetic factors are involved, interacting with environmental agents early in gestation to prevent closure of the neural tube. The number of the mutant genes is unknown...

OBJECTIVE Central nervous system (CNS) anomalies are the most common abnormalities of all malformations and can be diagnosed on routine prenatal ultrasonography (US). We aimed to find out fetal CNS anomaly rate in our clinic which is the referral center in the region. METHODS This is a retrospective study of 15000 pregnant women who were scanned for routine obstetric follow-up from January 20...
