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.

ar·te·ri·o·scle·ro·sis (är-tîr--skl-rss)

n.

Any of a group of chronic diseases in which thickening, hardening, and loss of elasticity of the arterial walls result in impaired blood circulation. Also called arterial sclerosis.

ar·teri·o·scle·rotic (-rtk) adj.

---

Arteriosclerosis

A chronic condition characterized by thickening and hardening of the arteries and the build-up of plaque on the arterial walls. Arteriosclerosis can slow or impair blood circulation.

Mentioned in: Aneurysmectomy, Angiography, Atherosclerosis, Dizziness, Gangrene, Hypertension, Hypotension

arteriosclerosis

[ärtir′ē·ō′sklərō′sis]

Etymology: Gk, arteria + sklerosis, hardening

a common disorder characterized by thickening, loss of elasticity, and calcification of arterial walls. It results in a decreased blood supply, especially to the cerebrum and lower extremities. The condition often develops with aging and in hypertension, nephrosclerosis, scleroderma, diabetes, and hyperlipidemia. Typical signs and symptoms include intermittent claudication, changes in skin temperature and color, altered peripheral pulses, bruits over an involved artery, headache, dizziness, and memory defects. Vasodilators and exercise may relieve symptoms, but there is no specific treatment. Preventive measures include therapy for predisposing diseases, adequate rest and exercise, avoidance of stress, and discontinuation of tobacco use. Kinds of arteriosclerosis include atherosclerosis and Mönckeberg's arteriosclerosis. Also called arterial sclerosis, hardening of the arteries. arteriosclerotic, adj.

arteriosclerosis (ärtir´ēōsklerō´sis),

n a term applied to a group of diseases that affect the elasticity of the blood vessels. It may refer to atherosclerosis, hyperplastic arteriosclerosis, or Mönckeberg's sclerosis. These degenerative processes generally affect only the tunica media and tunica intima. The effect is narrowing of the lumen of a blood vessel, causing rupture of the blood vessel or ischemia of an area of tissue that the vessel supplies.

arteriosclerosis

a group of diseases of humans characterized by thickening and loss of elasticity of the arterial walls. Of no importance in animals.

---

Monckeberg's arteriosclerosis

medial calcific sclerosis of humans.

arteriosclerosis 

Thickening and hardening of the walls of arteries which results in an obstruction of the blood flow. It is most frequently the result of hypertension but in the elderly it can develop in the absence of hypertension. In the retina, the branches of the central retinal artery may become straightened at first, later they become lengthened and tortuous, the arteriovenous (A-V) crossings are abnormal. Arteries resemble 'copper wire' as they become infiltrated with lipid deposits and eventually as 'silver wire' as the deposits increase and the whole thickness of the artery appears as a bright white reflex. Some retinal oedema may be present and as the disease progresses there are retinal haemorrhages and small sharp-edged exudates without surrounding oedema. This retinal condition is called arteriosclerotic retinopathy. See atherosclerosis; anterior ischaemic optic neuropathy; hypertensive retinopathy; sphygmomanometer.

arteriosclerosis

ASHD, hardening of the arteries Cardiology ASHD's early effects are in the lower extremities, with subtotal occlusion and decreased ability to withstand exercise without frequent rest periods; atherosclerosis is a generic term for arterial 'hardening'–calcium deposition, sclerosis, and thickening by fibrous tissue with loss of elasticity forms of arteriosclerosis including atherosclerosis–in which there is lipid deposition, Mönckeberg sclerosis, arteriolosclerosis; it is a common disorder usually affecting > age 50 and refers to any of a group of diseases characterized by thickening and hardening of the artery wall and in the narrowing of its lumen Risk factors Personal or family history of coronary artery or cerebrovascular disease, DM, HTN, kidney disease involving hemodialysis, smoking, or obesity. See Atherosclerosis, Hyaline arteriosclerosis

Arteriosclerosis

Arteriolosclerosis

• Benign–associated with hyaline arteriolosclerosis
• Malignant–associated with myofibroblast hyperplasia, 'onion-skinning' of endothelial basement membrane and deposit of fibrinoid material in vascular wall

Atherosclerosis

Formed by cholesterol and cholesterol esters, covered by a fibrous plaque which, with time becomes calcified, ulcerated and causes thromboembolism in coronary artery disease–strokes, MIs, leg ischemia-especially in DM, ischemia of large intestine

Mönckeberg sclerosis

Idiopathic and often asymptomatic annular calcified bands occurring in the muscular media of medium to small blood vessels of the extremities that have been fancifully likened to a goose's neck
