What is chronic arterial occlusive disease?

What is chronic arterial occlusive disease?

Chronic arterial occlusive disease is a highly prevalent peripheral vascular disorder. This disease is caused by arteriosclerosis obliterans (ASO), thromboangiitis obliterans (Buerger’s disease), primary arterial thrombosis, embolism and so on. Of these, ASO is the most frequently encountered.

What is chronic arterial?

Chronic arterial insufficiency (CAI) is a common condition affecting predominantly older patients. It normally involves the lower limbs and is usually due to progressive furring up and hardening of the arteries due to atherosclerosis.

What is lower extremity arterial occlusive disease?

Lower extremity arterial disease—also known as peripheral artery disease, lower extremity—occurs when plaque forms in a leg artery, blocking blood flow. Plaque is composed of fat, cholesterol, calcium, and other substances in the blood.

What causes vascular occlusive disease?

Occlusive peripheral arterial disease is blockage or narrowing of an artery in the legs (or rarely the arms), usually due to atherosclerosis and resulting in decreased blood flow. Symptoms depend on which artery is blocked and how severe the blockage is.

What is the difference between classic claudication and asymptomatic claudications?

Asymptomatic: Without obvious symptomatic complaint (but usually with a functional impairment). Classic claudication: Lower extremity symptoms confined to the muscles with a consistent (reproducible) onset with exercise and relief with rest.

What is the goal of physical therapy for peripheral vascular disease?

First, with respect to the affected limb or limbs, the goal is to eliminate ischemic symptoms and prevent progression to vascular occlusion.

What is the ABI of lower extremity arterial disease?

Lower extremity arterial disease is defined by a low ABI, usually ≤0.9 but ranging in the literature from <0.80 to <0.97. 31213141516 The incidence of asymptomatic lower extremity arterial disease in the 55- to 74-year-old age group is about 10% when an ABI <0.9 is used as a reference standard. 17

What is the best treatment for lower extremity arterial disease?

At present the best treatment for this indication appears to be aspirin, 75 to 325 mg daily. 6 Ticlopidine is a reasonable alternative for patients who are intolerant of aspirin. 78910 The purpose of this paper was to develop guidelines for the treatment of patients with lower extremity arterial disease.
