An aneurysm is a weakening in the side of a blood vessel, which causes a small sac of blood to form. This can occur in blood vessels of the brain (cerebral aneurysm), heart (aortic aneurysm) or limbs (peripheral aneurysm).
Overview
This situation becomes urgent only if the aneurysm bursts. In the case of a ruptured brain aneurysm, a person would experience a stroke due to blood flowing into the brain. A call to 911 and transportation to the emergency department are the first important steps in getting help for this condition.
University of Minnesota Medical Center is a Primary Stroke Center, as designated by The Joint Commission, an independent organization that accredits and certifies health care organizations and programs in the United States. As a Primary Stroke Center, we have demonstrated exceptional efforts to deliver better outcomes for stroke patients. We partner with other hospitals to support high quality standards for Minnesotans who receive stroke care.
Our approach
Small aneurysms usually don’t have symptoms and may not cause problems. But as they enlarge you may experience headaches or pain, difficulty with vision, speech, thinking skills, or seizures. You may also experience numbness, weakness in one or more limbs, or have difficulty walking.
Your doctor will take your blood pressure, because having high blood pressure is a leading cause of stroke. You’ll also be asked about any medication you may be taking, such as blood thinners, diet pills or other substances that may increase your risk for stroke. A complete health history will help determine your diagnosis and treatment plan.
An aneurysm is diagnosed through diagnostic imaging such as MRI or CT scan. You may also receive an angiogram, in which a small catheter is inserted through a blood vessel in the groin and guided to the site of the aneurysm. Your doctor is able to take pictures of blood vessels in the brain to diagnose any problems.
The best treatment options depend on the size and location of the aneurysm. Your doctor will talk with you about the recommended treatment options.
