What Is An Aneurysm?
by Dr. Thomas K. Lo, Advanced Chiropractic & Nutritional Healing Center
An aneurysm is a weak or expanded part of an artery, like a bulge in a balloon. Your arteries are large blood vessels that carry oxygenated blood from your heart to other parts of your body. If an area in an artery wall weakens, the force of blood pumping through can result in a bulge or aneurysm.
Aneurysms usually aren’t painful. You might not know you have one unless it ruptures or bursts. If it does, it can be very dangerous or even fatal.
Different Types of Aneurysms
An aneurysm can form in any of the arteries in your body. Aneurysms can occur in your heart, abdomen, brain, or legs. The location determines the type of aneurysm.
Aortic aneurysms are by far the most common. They form in your aorta, your body’s largest artery. Your aorta carries blood out of your heart. Aneurysms that develop in arteries other than your aorta are called peripheral aneurysms.
Types of aneurysms include:
Abdominal aortic aneurysm (AAA): These aneurysms may form where your aorta carries blood into your abdomen (belly).
Cerebral aneurysms: Also called brain aneurysms, these aneurysms affect an artery in your brain. A saccular (or berry) aneurysm is the most common type of cerebral aneurysm. It forms as a sack of blood attached to an artery. It looks like a round berry attached to the artery.
Thoracic aortic aneurysm: These aneurysms form in the upper part of your aorta, in your chest.
Carotid aneurysm: These aneurysms form in your carotid arteries. These blood vessels bring blood to your brain, neck, and face. Carotid aneurysms are rare.
Popliteal aneurysm: These develop in the artery that runs behind your knees.
Mesenteric artery aneurysm: This type of aneurysm forms in the artery that brings blood to your intestine.
Splenic artery aneurysm: These aneurysms develop in an artery in your spleen.
How Common Are Aneurysms?
Unruptured brain aneurysms affect 2 to 5 percent of healthy people, and about 25 percent of them have multiple aneurysms. Most brain aneurysms develop in adulthood—but they can also occur in children—with a mean age of detection around 50 years in adults. Many brain aneurysms don’t rupture.
Aortic aneurysms become more prevalent with age.
Abdominal aortic aneurysms are four to six times more common in males than females.
Who Is At Risk of An Aneurysm?
Different types of aneurysms affect different groups. Brain aneurysms affect females more than males. Aortic aneurysms more often affect males.
Abdominal aortic aneurysms occur most often in people who are:
Male.
Over the age of 60.
Smokers.
White, although they affect people of any race.
What Are the Symptoms of An Aneurysm?
In many cases, people don’t know they have an aneurysm. If an aneurysm ruptures (bursts), it’s a medical emergency that requires immediate treatment. Call 911 if you or someone you’re with shows signs of a ruptured aneurysm.
Symptoms of a ruptured aneurysm come on suddenly. You may feel:
Lightheaded.
Rapid heartbeat.
Sudden, severe pain in your head, chest, abdomen, or back.
Sudden loss of consciousness following a severe headache.
When an aneurysm causes symptoms, the signs depend on its location. You might notice signs of shock, such as a drop in blood pressure, feeling clammy and “out of it,” and having a pounding heart. Other symptoms of an aneurysm can include:
Confusion or dizziness.
Difficulty swallowing.
Fatigue.
Headache.
Nausea or vomiting.
Pain in your abdomen, chest, or back.
Pulsating abdominal mass or swelling in your neck.
Rapid heart rate.
Vision changes.
What Are the Complications of An Aneurysm?
If an aneurysm ruptures, it causes internal bleeding. Depending on the location of the aneurysm, a rupture can be very dangerous or life-threatening.
An aneurysm in your neck can cause a blood clot that travels to your brain. If the clot cuts off blood flow to your brain, it causes a stroke.
When a brain aneurysm ruptures, it causes a subarachnoid hemorrhage. Some people call this type of stroke a brain bleed. Typically, people have what they call the worst headache of their life and then develop other symptoms like limb weakness, headache, and trouble speaking.
What Causes An Aneurysm?
In some cases, people are born with aneurysms. They can also develop at any point during your life. Although the cause of an aneurysm is often unknown, some possible causes include:
Atherosclerosis (narrowing of the arteries).
Family history of aneurysms.
High blood pressure.
Injury to your aorta.
How Is An Aneurysm Diagnosed?
Many aneurysms develop without causing symptoms. Your healthcare provider may discover it by accident during a routine checkup or other screening.
If you have symptoms that may indicate an aneurysm, your provider will do imaging tests. Imaging tests that can find and help diagnose an aneurysm include CT scan, CT or MRI angiography, and Ultrasound.
How Will My Healthcare Provider Classify An Aneurysm?
Your provider will classify an aneurysm by how large it is and how it forms. The different classifications include:
Fusiform aneurysm bulges out on all sides of your artery.
Saccular aneurysm causes just one side of your artery to bulge.
Mycotic aneurysm develops after an infection (typically in your heart valves) has weakened an artery wall.
Pseudoaneurysm or false aneurysm occurs when just the outer layer of your artery wall expands. This can occur after injury to the inner layer of your artery called dissection.
How Is An Aneurysm Treated?
If your provider discovers that you have an unruptured aneurysm, they’ll monitor your condition closely. The goal of treatment is to prevent the aneurysm from bursting.
Depending on the aneurysm’s type, location, and size, treatment can include medication or surgery. Your provider may prescribe medications to improve blood flow, lower blood pressure, or control cholesterol. These treatments can help slow aneurysm growth and reduce pressure on the artery wall.
Large aneurysms at risk of bursting may require surgery. You’ll also need surgery if an aneurysm bursts.
How Can I Prevent An Aneurysm?
Unruptured aneurysms are common. You can’t always prevent them. But you can reduce your risk of developing an aneurysm by maintaining a healthy lifestyle:
Eat a heart-healthy diet.
Exercise regularly.
Maintain a healthy weight.
Avoid or quit smoking.
What Is the Prognosis for People With An Aneurysm?
Ruptured aneurysms are a life-threatening emergency. Without immediate treatment, it can be fatal. If you get treatment right away, the outcomes vary. Many people recover well with rehabilitation and other care.
