pneumonectomy

Full Definition

Pneumonectomy is the surgical removal of an entire lung, typically performed for lung cancer, severe infection, or trauma when lesser resections are inadequate. The procedure involves division of the pulmonary artery, pulmonary veins, and main bronchus on the affected side. Post-pneumonectomy patients require careful fluid management and monitoring for complications such as bronchopleural fistula or cardiac herniation into the empty thoracic space.

Usage

Usage note: Distinguish from lobectomy, which removes only a portion of the lung.
