Mönckeberg's arteriosclerosis

arteriosclerosis /ar·te·rio·scle·ro·sis/ (-sklĕ-ro´sis) a group of diseases characterized by thickening and loss of elasticity of the arterial walls, occurring in three forms: atherosclerosis, Mönckeberg's arteriosclerosis, and arteriolosclerosis.arteriosclerot´ic

Mönckeberg's arteriosclerosis  arteriosclerosis with extensive deposits of calcium in the middle coat of the artery.

arteriosclerosis obli´terans  that in which proliferation of the intima of the small vessels has caused complete obliteration of the lumen of the artery.

peripheral arteriosclerosis  arteriosclerosis of the limbs.

Mönckeberg's arteriosclerosis

[meng′kəbərgz]

Etymology: Johann G. Mönckeberg, German pathologist, 1877-1925

a form of arteriosclerosis in which extensive calcium deposits are found in the tunica media of the artery with little obstruction of the lumen. Also called medial arteriosclerosis.

arteriosclerosis [ahr-te″re-o-sklĕ-ro´sis]

any of a group of diseases characterized by thickening and loss of elasticity of the arterial walls; popularly called “hardening of the arteries.” Symptoms depend on the organ system involved. adj., adj arteriosclerot´ic.ƒ

There are three main forms of arteriosclerosis: (1) atherosclerosis, the most common type, in which plaques of fatty deposits form in the inner layer (tunica intima) of the arteries; (2) Mönckeberg's arteriosclerosis, called also medial calcific sclerosis because of involvement of the middle layer (tunica media) of the arteries, where there is destruction of muscle and elastic fibers and formation of calcium deposits; and (3) arteriolar sclerosis or arteriolosclerosis, which is marked by thickening of the walls of arterioles. All three forms may be present in the same patient, but in different blood vessels. When reference is made to hardening of the arteries, this usually refers to atherosclerosis; the terms arteriosclerosis and atherosclerosis are often used interchangeably.

It is the responsibility of the health care provider to help individuals modify or eliminate from their lives risk factors for the development of arteriosclerosis. These include cigarette smoking, obesity, elevated cholesterol levels, and sedentary life style.
