Sites of Atherosclerosis Atherosclerotic plaques develop primarily in elastic arteries (e.g., aorta, carotid and iliac arteries), and large & medium sized muscular arteries (e.g., coronary artery and poplitial arteries). In descending order, the vessels most commonly involved are - Abdominal aorta (most common) → Causing aneurysm Coronary arteries (heart) → Causing MI Popliteal arteries → Causing ischemic gangrene of lower limbs. Internal carotid arteries → Causing stroke Circle of willis → Causing stroke Vessels usually spared are Vessels of upper extremities Mesentric and renal vessels, except at their
