Signs of malformation in pregnancy

Today, with the continuous development of high technology, air pollution is coming one after another. If pregnant women are in a polluted environment for a long time, the probability of having a deformed fetus will immediately increase significantly. To date, the incidence of developmental malformations has been on the rise. In China, neural tube defects and cleft lip and palate are the most common fetal malformations. So, what are the symptoms of having a malformed fetus?

What are the symptoms of a malformed fetus?

⑴ Whole embryo dysgenesis: caused by serious genetic defects, generally can not produce complete test tube embryos, early death digestion or miscarriage.

⑵ Partial dysplasia of the test tube embryo: caused by disordered growth and development of the test tube embryo, usually resulting in simultaneous malformations of multiple organs. For example, facial dysplasia, synmelia, etc.

⑶ Malformations of human organs and parts of human organs: caused by the non-production or poor development of a certain organ, such as the non-production of both or one lung, damage to the ventricular septum, etc.

⑷ Deformity due to improper tissue division: Generally, this type of deformity occurs relatively late and is difficult to distinguish with the human eye. For example, bone dysplasia, cretinism, etc.

⑸ Excessive growth and development malformations: malformations caused by hyperplasia of human organs, such as closure or stenosis of the foramen ovale and syndactyly caused by excessive growth and development of the second septum during the formation period of the atrial septum.

⑹ Malabsorption malformation: During the process of embryonic development, some structures are completely or partially absorbed. If the absorption is incomplete, malformation will occur immediately. For example, webbed fingers (toes), esophageal atresia, etc.

⑺Supernumerary and disordered malformations: caused by supernumerary and abnormal organ primordium formation or formation in abnormal position, such as porous breast, disordered breast, double renal pelvis and double urethra, etc.

⑻ Growth and development arrest malformation: the growth and development of human organs are stopped halfway, and the human organs are in an intermediate state. For example, bicornuate uterus, cryptorchidism, pelvic kidney, tracheoesophageal fistula, etc.

⑼ Recurrent malformation: Recurrent malformation is caused by the inability to completely separate the two twins of monozygotic twins, resulting in the recurrence of different degrees of overall or partial structures of the fetuses.

⑽Endoparasitic malformation: Endoparasitic malformation is also known as parasitic fetus. The two babies of identical twins develop at very different rates, causing the smaller one to be attached to a nearby position.
