Abstract

Endobronchial ultrasound-guided transbronchial needle aspiration has a low complication rate and is a cost-effective procedure for mediastinal staging and diagnosis when compared with the more invasive mediastinoscopy. There are increasing case reports of unexpected complications including equipment failures with and without significant medical consequences. Knowledge of complications, including those that are rare, is essential for the physician performing this minimally invasive procedure. We report a case of a retained foreign body from the unexpected separation of a distal spring/coil mechanism from the Olympus ViziShot Aspiration needle following early needle deployment within the working channel of the bronchoscope.
