Where do Aneurysms most often occur?

Aneurysms most often occur in the brain (cerebral aneurysms) and in the aorta, the large blood vessel that carries blood from the heart to the rest of the body. In the aorta, they can develop in the thoracic (chest) or abdominal regions. Other common sites include the popliteal artery behind the knee and the femoral artery in the groin. These locations are particularly prone due to the high pressure and stress placed on the arterial walls.
