The utility of thoracic ultrasound before local anesthetic video-assisted thoracoscopy in patients with suspected pleural malignancy.

Video-assisted thoracoscopy under local anesthesia (VAT-LA) is a key investigation in the diagnosis and management of suspected malignant pleural effusion. Two problems encountered at VAT-LA are accessing the pleural space and fibrinous intrapleural septa. Thoracic sonography (TUS) is known to facilitate thoracocentesis after dry tap but has not been studied in detail before VAT-LA. We report a case of lateral decubitus pre-VAT TUS that helped locate the optimal access to the pleural space and demonstrated fibrinous intrapleural septation, thereby affecting the decision to avoid thoracoscopic pleurodesis.
