Brain Aneurysms (Cerebral Aneurysms)

Stony Brook is Your Brain Aneurysm Expert
Stony Brook Medicine has long been a leader in complex brain aneurysm treatment. As a result, clinical trial sponsors seek us out as a trial site, often making Stony Brook the first on Long Island or in the country to offer brain aneurysm treatment options not available elsewhere. Led by David Fiorella, MD, PhD, our brain aneurysm treatment team will work with you to determine the best plan for your particular brain aneurysm. If your aneurysm requires treatment, it's our goal to accomplish this easily and safely in a way that causes minimal disruption of your normal daily life.

Our multidisciplinary expert team offers both in person and telemedicine consultations for the treatment of all cerebrovascular disease processes. Contact us for a consultation:

What is a Brain Aneurysm?
A brain aneurysm occurs when the wall of an artery supplying blood flow to the brain bulges out to form a balloon-like structure. Arteries carry high-pressure blood flow from the heart to the organs of the body. The constant pressure within an artery can cause brain aneurysms to grow over time and eventually leak (or rupture). When a brain aneurysm leaks, this causes arterial force bleeding to occur and enter into the fluid space around the outside of the brain. This type of life-threatening bleeding is called a subarachnoid hemorrhage – which is a common type of hemorrhagic stroke.

  • Minimally Invasive Brain Aneurysm Treatments: Stony Brook Medicine has pioneered many of the most important minimally invasive treatments for brain aneurysms. Most all brain aneurysms requiring treatment can be treated at Stony Brook using minimally invasive endovascular techniques. We specialize in the treatment of complex brain aneurysms using technologies such as:

New Clinical Trials and Devices Expand Treatment Options for Wide-Neck Bifurcation Aneurysm

We are currently participating in multiple ongoing clinical research trials for brain aneurysm treatment that allow us to offer our patients the newest and most advanced brain aneurysm therapies. More from Dr. Fiorella on this topic here. 


  • Brain aneurysm clipping: Our cerebrovascular specialists perform open brain surgery and place a tiny metal clip at the base of your aneurysm to cut off its blood supply.
