[Pleural effusion: what next?]

Abstract

This article gives an overview of the aetiology, diagnostic evaluation and treatment of pleural effusions. A systematic approach including radiological and sonographic examinations and pleural fluid analysis is proposed with a view to selecting the most appropriate therapy. Common forms of exudative pleural effusions are explained in detail. For complicated parapneumonic effusions, new therapeutic options such as the use of fibrinolytics or thoracoscopic debridement are discussed. Talc slurry and thoracoscopic talc poudrage provide effective methods for pleurodesis in case of malignant effusions.
