A brain aneurysm -- a weakened or bulging portion of an artery in the brain -- can be emergent or stable. If a rupture has occurred, our neurosurgeons work quickly to repair damage and reduce the risk of complications. If your brain aneurysm is stable, small, and has not ruptured, Duke radiologists, neurologists, and neurosurgeons use sophisticated imaging tools to determine whether you will benefit from observation or treatment. We perform open surgery or complex, minimally invasive catheter procedures to repair aneurysms.

MRI or CT Scans
High resolution, 3-D images of the brain and its blood vessels are reviewed to analyze the size, shape, and location of the aneurysm, as well as potential bleeding or spasms that may signal an increased risk for stroke. These tests take about 30-60 minutes, and are virtually painless. When MRI or CT scans are used to examine blood vessels (angiograms), they are called MRAs and CTAs.
Through a small incision, a catheter is inserted into one of your major arteries and threaded through the circulatory system to your neck. Then a contrast dye is injected into the catheter and travels to the brain’s arteries, which highlights the location and severity of the aneurysm. Overall, this test takes about an hour and requires you to lie flat afterward for two to four hours.
Why Choose Duke
Emergency Diagnosis and Response
Many cerebrovascular diseases aren’t diagnosed until after a serious complication occurs. Our team is the region's leading resource for brain health emergencies, including aneurysms.
Advanced Training and Experience
Our neurologists, neurosurgeons, and radiation therapists are trained and experienced in the full range of aneurysm prevention, management, and treatment. Blood-flow disorders in the brain can be difficult to diagnose, but our specialists have the advantage of doing so regularly. From emergency situations in which weak artery walls create immediate risk, to less urgent cases where a comprehensive assessment determines whether surgery is necessary, we ensure you receive the most appropriate treatment for your condition.
Complex Procedures, Successful Outcomes
Unlike some hospitals, we are equipped and trained to perform surgery on large aneurysms, which is an extremely complex and often lifesaving procedure.
Sophisticated Microsurgical Techniques
Our surgeons use powerful microscopes that allow them to see tiny vascular structures in detail and in real time. This makes complex aneurysm surgeries safer and more precise.
Diagnostic and Imaging Expertise
We use the most advanced equipment and procedures to diagnose and treat brain aneurysms, including high-resolution 3-D imaging of blood vessels in the brain. These tools enhance our ability to review your medical situation and present the safest and best treatment options.
