Raynaud disease is idiopathic, intermittent spasm of the arterioles in the digits, which causes skin pallor. Arteriosclerosis obliterans is occlusion of the blood supply to the extremities by atherosclerotic plaques. Giant cell arteritis is a generalized inflammatory disease that affects the carotid, temporal, and occipital arteries. An aneurysm is dilation of an artery caused by a weakness in the arterial wall. Aneurysms occur in the aorta, renal, femoral, and popliteal arteries.
