calcific plaque
Atherosclerotic deposits containing calcium that appear as high-density areas on CT and acoustic shadows on ultrasound, affecting treatment planning.
Full Definition
Calcific plaque refers to atherosclerotic deposits that contain significant calcium deposition, appearing as high-density areas on computed tomography and creating acoustic shadowing on ultrasound examinations. The presence and distribution of calcification within arterial walls significantly impacts treatment planning and procedural success rates. Heavy calcification can complicate balloon angioplasty, reduce stent expansion, and may require specialized techniques such as atherectomy or cutting balloons for optimal results. Calcium scoring and distribution patterns help predict procedural complexity and guide device selection.
Usage
Usage note: Distinguish between intimal calcification and medial sclerosis when describing calcium patterns.
In Context
- "Extensive calcific plaque was noted throughout the superficial femoral artery, requiring atherectomy preparation." — Pre-procedural assessment
- "The calcific plaque created significant acoustic shadowing, limiting ultrasound evaluation of the vessel lumen." — Duplex ultrasound limitation
