vessel calcification
Calcium deposition within arterial walls that affects vessel compliance and complicates endovascular interventions.
Full Definition
Vessel calcification involves calcium phosphate crystal deposition within arterial walls, creating rigid, incompressible segments that significantly impact endovascular treatment planning and outcomes. Calcification patterns include intimal (associated with atherosclerotic plaques) and medial (Mönckeberg's sclerosis) types, each presenting different clinical challenges. Heavily calcified vessels resist balloon expansion, increase risk of vessel rupture, and may require specialized interventional techniques such as cutting balloons, atherectomy devices, or high-pressure balloon inflation. Preprocedural imaging assessment of calcification patterns helps guide device selection and procedural planning. Calcification severity affects long-term patency rates and may influence decisions between endovascular and surgical revascularization approaches.
Usage
Usage note: Describe pattern and severity of calcification when documenting lesion characteristics in procedural reports.
