Implication

Randomized trial examines the relationship between medial and intimal calcification in lower extremity artery disease, suggesting distinct pathological insights.

Key Points

This study aims to analyze the distribution and relationship between medial and intimal artery calcification in lower extremity artery disease.
Conducted a systematic histopathological analysis of 3,566 cross-sections from 125 arterial segments in 58 patients.
Quantified calcification by circumferential arc and classified plaque morphology using modified American Heart Association criteria.
Medial artery calcification (MAC) was present in 91.2% of segments and more extensive in below-the-knee arteries.
Identified advanced medial bone formation in 16.0% of segments, closely associated with high MAC burden.
In-versely correlated arcs of MAC and intimal artery calcification (IAC) (r = -0.47; P < 0.0001), indicating spatial segregation.
