lymphedema
Pronunciation: LIMF-eh-DEE-mah
Chronic swelling caused by impaired lymphatic drainage, often affecting extremities.
Full Definition
Lymphedema is a chronic progressive condition characterized by accumulation of protein-rich fluid in tissues due to impaired lymphatic drainage, resulting in persistent swelling, skin changes, and increased infection risk. This condition can be primary (congenital lymphatic abnormalities) or secondary (acquired due to surgery, radiation, infection, or trauma), with the lower extremities most commonly affected. In vascular medicine documentation, lymphedema requires differentiation from venous edema through clinical assessment and specialized testing, with staging based on severity and response to elevation, requiring precise terminology for optimal patient care coordination.
Usage
Usage note: Distinguish from venous edema and lipedema; specify primary versus secondary etiology when known.
