What Is an Aneurysm?

An aneurysm is a bulging, weakened area in the wall of a blood vessel. Aneurysms can occur in any blood vessel in the body, but they are most common in the aorta, the large artery that carries blood from the heart to the rest of the body.

Aneurysms can be caused by a variety of factors, including:

* High blood pressure

* Arteriosclerosis (hardening of the arteries)

* Smoking

* Diabetes

* Obesity

* Family history of aneurysms

Aneurysms can be dangerous because they can rupture, causing life-threatening bleeding. The risk of rupture depends on the size, location, and shape of the aneurysm.

Small aneurysms may not cause any symptoms. However, larger aneurysms can cause a variety of symptoms, including:

* Pain

* Pulsation

* Swelling

* Difficulty swallowing

* Hoarseness

* Headaches

* Dizziness

* Confusion

If you experience any of these symptoms, it is important to see a doctor immediately.

Aneurysms are often diagnosed with imaging tests, such as ultrasound, computed tomography (CT) scans, and magnetic resonance imaging (MRI) scans.

Treatment for aneurysms depends on the size, location, and shape of the aneurysm. Treatment options may include:

* Medications to lower blood pressure and cholesterol

* Surgery to repair or remove the aneurysm

* Endovascular surgery, a minimally invasive procedure that uses a catheter to repair the aneurysm

If you have an aneurysm, it is important to follow your doctor's instructions for treatment and monitoring.
