Symptoms of patent foramen ovale

summary

Foramen ovale is a vital channel for fetal development. It is through this channel that the umbilical vein blood from the mother enters the left cardiac cavity of the fetus, and then distributes to the whole body to provide oxygen and nutrients for fetal development. When the baby was born, with the first cry, the left atrial pressure increased, making the left primary septum cling to the right secondary septum, resulting in functional closure, and reaching anatomical closure within one year. If the foramen ovale of children over 3 years old is still not closed, it is called patent foramen ovale.

Symptoms of patent foramen ovale

In recent years, many studies have shown that the occurrence of patent foramen ovale disease is closely related to patients with unexplained stroke. This is because through the patent foramen ovale, after the occurrence of this disease, patients will have lower extremity deep vein or pelvic vein thrombosis.

The problem of patent foramen ovale may also lead to air embolism caused by diving disease or decompression sickness; The risk of recurrence of fat emboli after surgery or trauma is still high for patients with patent foramen ovale who have had thrombosis.

Lip blackening is a typical symptom of patent foramen ovale. We can also make the initial judgment through these common sense. Patent foramen ovale is a congenital heart disease, which easily leads to insufficient blood pump of the heart, so it leads to lip blackening. If the central atrial septal defect is large, larger than 8-10 mm, with large shunt, it is called central atrial septal defect and needs surgical repair.

matters needing attention

Therefore, it is expected to reduce the incidence of patients by closing the open foramen ovale in high-risk groups. In addition, we also found that patent foramen ovale is related to decompression sickness and migraine, and closure of foramen ovale may be beneficial to these patients.
