Does taking an aspirin every day prevent an aneurysm from rupturing?

Dr. Geoffrey P. Colby, MD
There is no medicine or pill that can definitely prevent an aneurysm from growing or rupturing.

There is, however, evidence from some clinical studies that medications people take to reduce inflammation in other parts of the body might also reduce the risk of rupture of an intracranial aneurysm. In one recent study patients who took a mini-dose aspirin, a baby aspirin or a single aspirin every day for its protective effect against atherosclerosis seemed to have a lower risk of rupture for intracranial aneurysms.

That doesn't mean that people with aneurysms should start taking an aspirin every day -- it's usefulness for preventing hemorrhaging is still being investigated, and this decision should be discussed with your doctor.

Over the next few years the relationship between arterial inflammation and the risk of intracranial aneurysm rupture may be clearer.
