There is a possibility of detachment after one month after the foramen ovale blockage, but the chances of detachment are relatively small. About one month after foramen ovale occlusion there is a possibility of detachment although the body epithelial cells have begun to grow over the blocker, but they have not yet completely covered it. Or it may be dislodged due to the presence of factors such as the mismatch between the size of the blocker and the size of the defect, the inappropriate positional pattern of the blocker release, and the exposure to abnormal external forces. However, since the occluder itself can withstand a certain amount of tension, most of the general activities will not cause the occluder to shift or fall off, so the chances of the occluder falling off after one month of occlusion surgery are very small. Therefore, it is recommended that patients should have regular postoperative checkups, and if any abnormality is found, they should consult a doctor in time and be treated under the guidance of a professional physician.
