The cost of surgery for patent foramen ovale is mostly between 20,000 and 30,000 RMB, which can be varied by hospital area, level and local health insurance policy, etc. It is recommended to consult with local hospitals directly. Ovarian foramen magnum does not require treatment if there is no abnormality, but if it is accompanied by unexplained stroke, venous thrombosis, increased right atrial pressure, etc., it needs to be treated accordingly. Surgical repair has been replaced by interventional therapy in most cases. The cost of interventional therapy is relatively high, ranging from 20,000 to 30,000 RMB in total, and may vary from region to region. The prognosis is good if the abnormality is accompanied by timely treatment. If there is an indication for surgery, it is recommended to follow the doctor’s instructions and ensure adequate rest and regular checkups after the operation.
