Endovascular is a term that refers to “inside the blood vessels.” An aneurysm is the bulging or ballooning of a weakened area of a blood vessel.

• The wall of the aorta (the largest blood vessel in the body) can become weak due to age
• High blood pressure
• Disease
• Trauma.

This may cause the aortic wall to bulge, leading to an aortic aneurysm. As the bulge grows, the wall of the aorta becomes weaker. This may cause the aorta to rupture and lead to massive internal bleeding.
A ruptured aneurysm requires immediate medical attention. In most cases, patients have no symptoms. However, for those patients with symptoms, the most common are pain in the abdomen, back, or chest.
