Produced by Rajiv Thavanathan, Podcast editing by Richard Hoang, Blog post written by Tanishq Suryavanshi, edited by Anton Helman, February, 2020 What is tension hydrothorax? Tension hydrothorax is a massive pleural effusion presenting with hemodynamic abnormalities secondary to mediastinal compression. Massive is defined as occupying greater than 2/3rd of the hemithorax, with 10% of pleural effusions being massive. Causes of tension hydrothorax Tension hydrothorax can result from a number of causes, including: Trauma, chylothorax, pancreatitis, cirrhosis, parapneumonic effusions, and autoimmune diseases, but by far the most common cause is malignancy. Indications for tube thoracostomy for hydrothorax * Associated pneumothorax or hemothorax * Respiratory and/or hemodynamic instability * Grade III–V parapneumonic effusions While there are no absolute contraindications to tube thoracostomy in patients with tension hydrothorax, adherence of the lung to the chest wall and history of pleurodesis are relative contraindications, in which case a thoracentesis may be indicated.
