Thoracocentesis of loculated pleural effusions using grey scale ultrasonic guidance.

Journal Article (Journal Article)

Six patients with either malignant pleural effusion or empyema, in whom multiple conventional attempts at thoracocentesis were unsuccessful, were evaluated by ultrasound. In each case, a subsequent thoracocentesis guided by ultrasound produced sufficient fluid to enable a diagnosis to be established. In no case was pneumothorax produced.
