Cryoprobe Retrieval of an Airway Foreign Body: A Case Report and Literature Review
2019
Abstract We report a case of a 7-year-old boy with clinical and radiographic evidence of foreign body (FB) aspiration with a 2-week delay in diagnosis. The retrieval of the pushpin with traditional bronchoscopic instrumentation was made difficult by granulation tissue formation. A cryoprobe through a flexible bronchoscope was used to successfully remove the FB. To our knowledge, this is the first report of interventional bronchoscopy with a cryoprobe to remove a pushpin in a child under suspension laryngoscopy and spontaneous ventilation. A high index of suspicion is crucial for identifying FBs early and minimizing granulation tissue development which complicates FB removal.
