What is an Aneurysm?

Aneurysms can occur in any blood vessel, but they typically develop in the abdominal or thoracic sections of the aorta, the primary blood vessel transporting blood from the heart, or in the arteries supplying blood to the brain.

The most significant danger posed by an aneurysm is its potential rupture, resulting in a stroke or severe bleeding, both of which can be fatal. Additionally, a sizable aneurysm can impede circulation and increase the risk of blood clot formation.

It's important to get it diagnosed and treated early. Aneurysms often have mild symptoms or none at all, so routine exams can help your doctor check for warning signs.

What Are the Types of Aneurysms?

Aortic aneurysm. As the name suggests, this type happens in your aorta. It can be linked with hardening of the arteries, also known as atherosclerosis. It may be an inherited condition or a complication of high blood pressure or smoking.

Cerebral aneurysm. Also known as a berry aneurysm, you get this kind in the wall of a blood vessel in your brain. Smoking raises your risk of getting one.

Popliteal artery. One of the more common peripheral vascular aneurysms, it is a bulging or weakness in the wall of the artery that supplies blood to the knee joint, calf and thigh.

Ventricular aneurysm. This is a bulge in the wall of your heart. A previous heart attack is the most common cause. In rare cases, a severe chest injury can also lead to it.

What Causes an Aneurysm?

Any condition that causes your artery walls to weaken can bring one on. The most common culprits are atherosclerosis and high blood pressure.

Deep wounds and infections can also lead to an aneurysm. Or you may be born with weakness in one of your artery walls.

How Is an Aneurysm Diagnosed?

To diagnose an aneurysm, your doctor will ask you questions, including whether another member of your family has had one. Then, they’ll give you a complete exam, during which they’ll:

• Listen to your heart

• Check your blood pressure

• Listen to the arteries in your neck

• Feel your abdomen for a mass

• Look behind the knee for popliteal aneurysms

How Is an Aneurysm Treated?

The only way to treat an aneurysm is to have it repaired with surgery or an endovascular procedure.

Sometimes, surgery isn’t possible, or it may pose more danger than the aneurysm. Careful monitoring and medication may be best in that case.

Your doctor will figure out the size, type, and location of the aneurysm. What they find will help determine your best treatment.
