Brain Aneurysms - What You Should Know About Endovascular Therapy
A brain aneurysm, also called a cerebral or intracranial aneurysm, is an abnormal bulging outward of one of the arteries in the brain. It is estimated that as many as one in 17 people in the United States will develop a brain aneurysm during their lifetime. Aneurysms can occur in people of any age, but are most commonly detected in those ages 35 to 60.
Brain aneurysms are often discovered when the rupture, causing bleeding into the brain or the space closely surrounding the brain, called the subarachnoid space. A subarachnoid hemorrhage from a ruptured brain aneurysm can lead to brain damage or death. Ten to 15% of these patients will die before reaching the hospital, and more than 50% will die within the first 30 days after rupture. Of those who survive, approximately half suffer some level of permanent brain damage.
Unruptured aneurysms are sometimes treatment to prevent rupture. The main goals of treatment once an aneurysm has ruptured are to stop the bleeding and potential permanent damage to the brain and to reduce the risk of recurrence.
