Generally, an arterial ductus arteriosus blocker can be detected by ultrasound because this blocker is mainly made of metal, and a specific image can be seen during the ultrasound examination. Arterial ductus arteriosus blocker is a specialized device for the treatment of arterial ductus arteriosus, which is mainly made of titanium alloy metal and nickel metal. The patient can dispose of a catheter in the femoral vein under the guidance of the doctor, and then place the blocker in order to block the arterial ductus arteriosus. Since these plugs are primarily made of metal, it is possible to detect an arterial ductus arteriosus plug during an ultrasound examination, which usually shows a specific image. However, not all people can have this type of blocker placed. If the diameter of the ductus arteriosus is relatively thick, then blocking surgery is not recommended, and the condition will have to be improved by other means, such as open-heart surgery.
