• An area of a blood vessel that bulges out due to weakening of the vessel walls. • If the bulge increases and/or the vessel continues to weaken, it may rupture. This can be life-threatening. o For example: A brain aneurysm rupture leads to hemorrhagic stroke, which can cause serious permanent brain damage or death. In the U.S., approximately 40% of ruptured brain aneurysms lead to death within 24 hours.¹
• There are two main forms of aneurysms: o Fusiform: the bulge occurs on all sides of the vessel. o Saccular: the bulge occurs only on one side of the vessel. • Aneurysms can occur in various arteries throughout the body. o Aortic aneurysms occur along the aorta (major artery that connects to the left side of the heart). o Peripheral aneurysms occur in arteries in other areas of the body.
• Common types of aneurysms include: o Cerebral aneurysm (brain) o Thoracic aortic aneurysm (chest) o Abdominal aortic aneurysm (abdomen, pelvis) o Mesenteric artery aneurysm (intestines) o Splenic artery aneurysm (spleen)
• Aneurysms often don’t create any symptoms, and a person may unknowingly have an unruptured aneurysm for years.
• Symptoms may include pain, headaches, nausea, low blood pressure, dizziness, rapid heartbeat, etc. • Emergency red flags: Loss of consciousness, vision changes, seizures, intense pain, and shock may be signs of a rupture.
• Different types of aneurysms have different causes, and we’re still learning about how they form. • Possible causes and risk factors include: o Birth defect o Smoking o High blood pressure o Poor diet and sedentary lifestyle o Obesity o Plaque buildup in arteries (atherosclerosis)
• Treatment varies depending on the type, location, cause, and state of the aneurysm.
• Ruptured aneurysms are typically treated by surgically reinforcing vessel walls, stopping blood flow, or diverting blood flow. • Unruptured aneurysms are commonly treated with medications and lifestyle changes that reduce pain and lower the risk of rupture.
• If you’re experiencing possible symptoms— especially if there’s a family history of aneurysms or relevant prior injury—it may be time to see a specialist. • If you’ve previously had an aneurysm and begin experiencing similar symptoms, see your vascular doctor as soon as you recognize them. • If you have severe symptoms that may indicate a rupture, do not wait for an appointment. Seek emergency medical care immediately, then make plans to see a specialist.
