In<unk> , the most commonly involved vessels include the left subclavian artery (50%), left common carotid artery (20%), brachiocephalic trunk, renal arteries, celiac trunk, superior mesenteric artery, and pulmonary arteries (50%). Infrequently, the axillary, brachial, vertebral, coronary, and iliac arteries are involved. The pathogenesis of<unk>  is poorly understood.<unk>  characterized by segmental and patchy granulomatous inflammation of the aorta and its major derivative branches.This inflammation leads to arterial stenosis, thrombosis, and aneurysms. Three factors that have been suggested to have association with susceptibility, development and progression of<unk>  are genetic inﬂuences, immunologic mechanisms and relationship to tuberculosis. The cause of<unk>  is idiopathic but genetic, immunologic and infectious factors play important role in the development of<unk> .<unk> kayasu arteritis has a worldwide distribution, it is observed more frequently in Asian countries such as Japan, Korea, China, India, Thailand, and Singapore. Female are more commonly affected. Common risk factors in the development of<unk>  include genetic predisposition, female sex, age <40, asian ethnicity. Common complications of<unk>  include hardening and narrowing of blood vessels, High blood pressure, Heart failure, Stroke, Transient ischemic attack. Common symptoms of<unk>  include headache, malaise, arthralgias, bruit, claudication, hypertension, visual disturbance. The most common finding is a systolic blood pressure difference (>10 mm Hg) between arms. Hypertension due to renal artery involvement is found in approximately 50% of patients. Absent or diminished pulses are the clinical hallmark of<unk> kayasu arteritis. Chest radiographs may reveal widening of the ascending aorta, irregular descending aorta, aortic calcifications, and rib notching (late findings). Most people with<unk>  respond to steroids such as prednisone. The usual starting dose is approximately 1 milligram per kilogram of body weight per day (for most people, this is approximately 60 milligrams a day). The two most important aspects of treatment: are controlling the inflammatory process and controlling hypertension.
