[Arteriosclerosis and media sclerosis. A comparison of 2 calcifying vascular diseases].

PATHOGENESIS: Arteriosclerosis and Mönckeberg's mediasclerosis are vascular diseases associated with calcification of the artery wall. While mediasclerosis in most cases develops in type 2 diabetic patients, arteriosclerosis is the result of a combination of different vascular risk factors. Mönckeberg's mediasclerosis typically involves the tunica media, whereas arteriosclerosis-associated calcifications primarily involve the intima. CLINICS: Isolated mediasclerosis does not cause narrowing of the blood vessel. The disease is usually asymptomatic, specific therapy has not yet been established. The involvement of the intima in arteriosclerosis finally leads to a decreased circulation.
