arterial calcification
Calcium phosphate deposits within arterial walls that affect vessel compliance and imaging interpretation.
Full Definition
Arterial calcification involves the deposition of calcium salts in arterial walls, which can occur in the intimal layer (associated with atherosclerotic plaques) or medial layer (Mönckeberg's sclerosis). This process reduces arterial compliance and can interfere with non-invasive pressure measurements, potentially leading to falsely elevated ankle-brachial index readings. Calcification patterns visible on imaging help assess cardiovascular risk and guide treatment planning.
Usage
Usage note: Distinguish between intimal calcification (atherosclerotic) and medial calcification (age-related or metabolic).
In Context
- "Extensive arterial calcification in this diabetic patient may render ABI measurements unreliable." — Diagnostic report
- "The presence of medial arterial calcification suggests advanced vascular disease despite normal luminal diameter." — Imaging interpretation
