What symptom does fetal neural tube defect have?
summary
Every family is very happy when they are pregnant. But many times, if they are not careful, the fetus will have a variety of situations. At present, congenital heart disease is more common, but it is not too serious. Recently, fetal neural tube malformation disease has appeared in clinical medicine, which is still very serious, Once diagnosed is the need for timely termination of pregnancy, but encounter such a phenomenon do not nervous, worry, ordinary heart face. So what are the symptoms of fetal neural tube defects? Let's talk about it now.
What symptom does fetal neural tube defect have?
In clinical medicine, if the fetus suffers from fetal neural tube malformation, the main manifestations are anencephalia, encephalocele, invisible spina bifida, cleft lip and other phenomena. Anencephaly and spina bifida are malformations that occur during the development of the fetus. Anencephaly mainly refers to the absence of a complete head. Generally, it will die in the uterus before birth, forming the phenomenon of stillbirth. Even if it is born, it will die in a short time. Spina bifida refers to the fetal spine bone is not well developed, will be prominent or exposed to the body surface, with the increase of age, produce different symptoms.
Anencephalia is a kind of severe DNT, which is characterized by the absence of all or most of the brain. The defect of the head starts from the top and extends to any part of the foramen magnum. Due to the absence of the cranial fornix, the child has a special facial appearance. The anterior cranial fossa shortens and the orbit becomes shallow, which makes the eyeball protrude forward, the mandible clings to the sternum, the mouth is half open, and the auricles are very thick, Protrusion from both sides of the head, showing a very strange "frog like face", can be accompanied by other parts of the body deformities, such as cleft palate, cervical spina bifida, narrow chest, imbalance of upper and lower limbs, absence of tibia and thumb, almost all with maternal amniotic fluid.
For example, the lesion is located in the lumbosacral region, with slow paralysis and muscle atrophy of the lower limbs, disappearance of sensation and tendon reflex, low temperature, cyanosis and edema of the lower limbs, nutritional ulcer, gangrene, muscle contracture, dislocation of the hip joint, horseshoe foot deformity, fecal and urinary incontinence, and some mild cases, Neurological symptoms may be mild.
matters needing attention
There are two ways to diagnose the fetus before birth. The first is non-invasive examination. First, observe the fetus's ultrasound and MRI. The examination can find out whether the fetus has fetal neural tube malformation. In this case, biochemical and fetal tissue analysis are common, such as analysis of alpha fetuses haploid and chorionic gonadotropin. The second is invasive examination, common amniocentesis, chorionic villus biopsy, fetal blood analysis and other examinations, can effectively diagnose whether the fetus has fetal neural tube malformation disease. If you have a pregnancy, you should end it in time.
