Abstract
The utility and safety of transbronchial needle aspiration is well described. Serious complications from transbronchial needle aspiration are exceedingly rare. The addition of endoscopic ultrasonographic techniques in the form of endoscopic ultrasonography and, more recently, endobronchial ultrasonography has added valuable information regarding lymphatic anatomy of the hilum and mediastinum. In addition, the use of real-time ultrasound gives the operator visual feedback of needle placement and proximity to major surrounding structures such as the heart and great vessels. Here, the authors present the case of a 74-year-old man with a left hilar mass who underwent biopsy by means of intentional traverse of the pulmonary artery.
