hemothorax
Accumulation of blood in the pleural space, commonly from chest trauma or iatrogenic injury.
Full Definition
Hemothorax is the presence of blood within the pleural cavity, most frequently resulting from penetrating or blunt chest trauma that damages intercostal vessels, lung parenchyma, or major thoracic structures. The condition can rapidly progress to respiratory compromise and hemodynamic instability depending on the rate and volume of bleeding. Treatment typically involves chest tube placement for drainage and monitoring, though massive hemothorax may require emergency thoracotomy for surgical control of bleeding sources.
Usage
Usage note: Often quantified as small, moderate, large, or massive based on volume and clinical impact
