An aneurysm is a bulge or weakness in the wall of a blood vessel. Aneurysms can enlarge over time and may be life threatening if they rupture. They can occur because of high blood pressure or a weak spot in a blood vessel wall. Aneurysms can occur in arteries in any location in your body. The most common sites include the abdominal aorta and the arteries at the base of the brain.
High blood pressure is the excessive force of blood pumping through your blood vessels. High blood pressure causes many types of cardiovascular disease, such as stroke and heart failure, and renal disease.
Peripheral arterial disease (PAD) is caused by atherosclerosis, which is the narrowing and / or blockage of the blood vessels in the legs. PAD manifests as pain in the legs when walking, which is relieved by rest. If you have PAD you are at greater risk of developing gangrene in your legs.
