The cost of the foramen ovale unclosed blockage surgery is about 20,000~30,000 RMB, which may vary from region to region and hospital to hospital, so it is recommended to consult with the local hospital directly. For patients with unclosed foramen ovale and symptoms (e.g. cryptogenic stroke, venous thrombosis, increased right atrial pressure, intractable migraine, etc.), interventional occlusion is mainly used to achieve anatomical closure of the unclosed foramen ovale through the use of an occluder to achieve a therapeutic effect. Usually, the cost is between 20,000 and 30,000 RMB, however, different medical insurance policies and hospital charges may lead to cost differences, so it is recommended to consult local hospitals directly. Ovarian foramen ovale closure requires timely treatment if surgical indication exists, and early treatment has a good prognosis. In order to avoid delaying treatment and worsening of the condition that affects the quality of life, it is recommended to follow the doctor’s instructions to carry out the relevant examinations and treatments.
