Substernal Thyroid Biopsy Using Endobronchial Ultrasound-guided Transbronchial Needle Aspiration
Published on: November 10, 2014
Needle aspiration biopsy of pulmonary, hilar, and mediastinal masses
Abstract:
The use of small needles (20 gauge or smaller) has made it possible to safely biopsy hilar and mediastinal masses as well as central and peripheral lesions in the lungs. The diagnostic accuracy of needle biopsy currently makes it the preferred method for obtaining tissue samples in patients with peripheral (non-endobronchial) lesions in the lung. Needle biopsy of the hilum and mediastinum frequently makes it possible to avoid more invasive procedures in the staging of patients with known or suspected bronchogenic carcinoma and to obtain a diagnosis in patients with mediastinal masses of unknown etiology.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
