TEHRAN-IRAN. Arda Kiani Department of Pulmonary Medicine, Azadeh Arab Department of Pulmonary Medicine, Journal Article 2021 02 11 Foreign Body (FB) aspiration is a life threatening event. Long interval between aspiration and removal can result in formation of granulation tissue around the FB. It can significantly affect the lung structure and manifest as a medical problem requiring surgery and increasing the related complications. It may also limit the visual field and extraction maneuver by flexible bronchoscope. In this case series we report 4 cases of FB aspiration in which FB is covered with granulation tissue and we also discuss different strategies to successful removal of these objects.
