pleural effusion
Accumulation of fluid in the pleural space complicating cardiac surgery recovery.
Full Definition
Pleural effusion is a common postoperative complication following cardiac surgery, involving fluid accumulation between the visceral and parietal pleura. Causes include inflammatory response to surgery, heart failure, infection, or chylothorax from lymphatic injury. Management depends on volume and symptoms, ranging from observation to chest tube drainage. Large effusions can compromise respiratory function and delay recovery, requiring drainage and investigation of underlying etiology.
Usage
Usage note: Distinguish from pneumothorax (air) or hemothorax (blood) in pleural space.
