Fetal finger deformities require amniocentesis.
Amniocentesis is an invasive means of obtaining fetal genes from amniotic fluid so that chromosomal analysis can be performed to screen for chromosome-related disorders.
Fetal finger deformities may be due to chromosomal abnormalities, and amniocentesis is used to perform chromosomal screening to determine whether chromosomal abnormalities are present.
If chromosomal abnormality exists, it may be combined with other malformations, which can be used as a reference to determine whether to continue the pregnancy. If chromosomal abnormality does not exist, the simple finger deformity may be related to abnormal bone development.
Therefore, when there are malformations of the fingers or other parts of the fetus, it is best to carry out amniocentesis to further clarify whether there is a genetic disease, and if necessary, can be avoided in the next pregnancy through assisted reproduction technology to avoid this risk.
