Causes. It is not clear exactly what causes aneurysms. Some aneurysms are present at birth (congenital). Defects in some parts of the artery wall may be a cause. Common locations for aneurysms include: Major artery from the heart such as the thoracic or abdominal aorta. Brain (cerebral aneurysm) Behind the knee (popliteal artery aneurysm)
Smoking. High blood pressure (hypertension) Strong family history of brain aneurysms (familial aneurysms) Age (over 40) Gender: women have an increased risk of aneurysms. Race: people of color have an increased risk of ruptured aneurysms.
