The purpose of prenatal check ups during pregnancy is actually to observe whether the fetus has congenital diseases. Congenital diseases are difficult to treat and can cause significant harm to infants. Congenital heart disease and other conditions can cause significant harm to infants. Therefore, it is necessary to constantly observe changes in the fetus during pregnancy. Sometimes it can be observed that the fetus has a U-shaped vascular ring. Is this congenital? Why does the fetus have a U-shaped vascular ring?
The fetal U-shaped vascular ring is not a disease, which means that the position of the blood vessels has changed. This situation is not a congenital malformation, but a morphological change.
If the fetus has a U-shaped vascular ring, parents don't need to worry, just go to the hospital for regular check ups and pay attention to the physical condition of the fetus at all times. If there are no abnormal conditions, no treatment is needed. If abnormal phenomena occur, surgical treatment is necessary.
The fetal U-shaped vascular ring, also known as the right aortic arch occlusion and left sternal aortic occlusion, often produces a capillary ring, which may be due to wrapping around the bronchi and esophagus. If this U-shaped vascular ring does not wrap around the bronchi or esophagus, surgical treatment is not required. For example, the current right arch and vagus left infrasternal aorta belong to all normal capillary gene variations, so treatment is not needed. If wrapped around the bronchi and esophagus, the vascular ring can be surgically removed to expose the compression on the trachea and esophagus.
