Medial artery calcification as an indicator of diabetic peripheral vascular disease.

Background: Mönckeberg sclerosis or medial artery calcification (MAC) is a well-known phenomenon associated with diabetic and other arterial disease. However, its consequence within the foot, and specifically the first dorsal metatarsal artery, has not previously been studied.

Materials And Methods: Nearly 1,000 foot x-rays were studied over a 9-month period in a busy hospital to identify the prevalence of first dorsal metatarsal artery calcification.
