Final answer:
Cardiac herniation post pneumonectomy refers to the displacement of the heart into the ipsilateral pleural space following surgical removal of a lung. This rare complication can result in compression of the heart and may require surgical repair to prevent life-threatening consequences.
Step-by-step explanation:
Cardiac Herniation Post Pneumonectomy
Cardiac herniation post pneumonectomy refers to the displacement of the heart into the ipsilateral (same side) pleural space following surgical removal of a lung (pneumonectomy). This rare complication occurs when the normal anatomical barriers that separate the heart and the lungs are disrupted, allowing the heart to move into the space previously occupied by the lung.
Cardiac herniation post pneumonectomy can result in compression of the heart, great vessel injury, and cardiac tamponade if the displaced heart comes under tension due to the negative pressure in the pleural space. This condition requires prompt intervention, usually including surgical repair, to prevent life-threatening consequences.
