[Ultrasound guided diagnostic procedures in the thorax].

Fluid in the pleural cavity, parenchyma masses and consolidation provide excellent sonographic windows for scanning. Ultrasound has proven extremely useful in directing interventional procedures in the pleural space, pulmonary parenchyma and mediastinum. Ultrasound offers a number of advantages over other imaging methods, the most important being the capability to monitor continuously the interventional procedures, thus assuring maximum safety and benefit. We will discuss the indications, technique, performances and complications of ultrasound guided thoracic puncture in the pleural space, pulmonary parenchyma and mediastinum.
