Obliterative Arteriosclerosis

Obliterative arteriosclerosis is progressive atherosclerotic occlusion of peripheral arteries, causing intermittent claudication, rest pain, ulcers, or gangrene. Treatment: smoking cessation; supervised exercise; antiplatelet; statin; control BP/diabetes; cilostazol for claudication; revascularization (angioplasty/stenting/bypass) for critical limb ischemia; wound care; amputate nonviable tissue if needed.

Common Symptoms

Claudication; rest pain; ulcers/gangrene; occluded peripheral arteries; smokers/older patients

Causes and Pathogenesis

Atherosclerotic plaque progresses to occlude peripheral arteries, causing limb ischemia.

Treatment

No smoking; exercise; antiplatelet/statin; revascularization for critical ischemia; wound care

Preventive Measures

No smoking; control risk factors; foot care.
