[Transbronchial needle aspiration of mediastinal masses during fiber-bronchoscopy]

The authors present their own experience in the diagnosis of thoracic adenopathies and mediastinal masses by transbronchial needle aspiration (Wang needle). The diagnostic usefulness and safety of the method is stressed. Radiology plays an important role in choosing biopsy site (by CT), in monitoring the procedure by fluoroscopy and looking for complications following completion of the examination.
