segmentectomy
Pronunciation: seg-men-TEK-toh-mee
Surgical removal of a specific anatomic segment of lung while preserving adjacent normal lung tissue.
Full Definition
Segmentectomy is a lung-sparing surgical procedure involving the anatomic resection of one or more pulmonary segments while preserving the remaining segments within the same lobe. This technique requires precise identification and division of the segmental bronchus, artery, and vein supplying the target segment. Segmentectomy is indicated for small peripheral tumors, limited pulmonary function, or when lobectomy would result in excessive loss of functional lung tissue. The procedure demands thorough knowledge of segmental anatomy and careful dissection techniques to avoid injury to adjacent structures.
Usage
Usage note: Specify the exact segments resected (e.g., superior segmentectomy, lingular segmentectomy).
