Transcatheter occlusion of a patent ductus arteriosus can be achieved with many devices. Gianturco embolization coils (11-cm wire diameter, 5- or 8-mm helical diameter) have been used to occlude a very small ductus arteriosus, such as the duct of Botallo.1

In our case, radiologic findings localized a radiopaque FB in the left hemithorax. Tracheobronchial FBs are potentially life threatening and may be associated with increased mortality and morbidity.2 Many studies have reported a male predominance, with a male-female ratio of 2:1.3,4 Most aspirated FBs occur in children younger than 3 years and are generally located in the right bronchial tree.3,5 The type of FB that is found is usually related to the age of the patient. Approximately 80% of FBs removed in children who are 5 years old or younger are some type of food item, whereas nonfood objects are found more frequently in older patients.5,6
