Aneurysm

Aneurysm is a bulge in the wall of an artery. Aneurysms form when there’s a weak area in the artery wall. Untreated aneurysms can burst open, leading to internal bleeding. They can also cause blood clots that block the flow of blood in your artery. Depending on the location of the aneurysm, a rupture or clot can be life-threatening.
