Brain Aneurysms

An estimated one in 50 Americans has an aneurysm, a sac formed by local enlargement of the weakened wall of an artery, a vein or the heart, caused by disease or injury. A ruptured aneurysm occurs every 18 minutes in the United States. Fortunately, advances in technology and surgical techniques have led to more successful treatments and better outcomes for people with an aneurysm. The experts at Indiana University Health are recognized leaders in detection and treatment of aneurysms. We provide the hands-on experience, surgical skill and sophisticated technology required for aneurysm care. As Indiana’s only certified Comprehensive Stroke Center, IU Health is in the top 2 percent of hospitals in the nation for stroke care.  

With a commitment to leading-edge technology, the physicians at IU Health provide diagnostic testing using the latest brain-scan equipment. Sophisticated magnetic resonance imaging (MRI), computed tomography scan (CT scan), and CT and cerebral angiography imaging allow our physicians to pinpoint the exact location, size and shape of an aneurysm. This leads to highly precise and more successful treatment.

IU Health is a national leader in treating people with aneurysms, using innovative treatments options. We offer advanced surgical treatments, including:

Coil Embolization

In this delicate procedure, one of our experienced interventional neuroradiologists inserts a catheter—a thin, flexible tube—into an artery in the groin and guides it directly into the aneurysm. Then, tiny metal coils are threaded through the catheter into the aneurysm. The coils fill the aneurysm, blocking its blood supply and "starving" the aneurysm, eventually causing it to shrink.

Surgical Clipping

Clipping is a surgical procedure used to cut off an aneurysm's blood supply; it can also be used when it does rupture. In this procedure, our skilled neurosurgeons make a small opening in the skull and place a tiny clip at the base of the aneurysm. The clip blocks blood from entering the aneurysm, which can prevent a rupture and cause the aneurysm to shrink. Clipping is a well-established treatment option for aneurysms.
