Where do aneurysms occur in the body?

Cardiology (Cardiovascular Disease)
Aneurysms can occur anywhere along the aorta, and in other blood vessels. The two most common aneurysms are of the thoracic aorta, which is in your chest (thorax), and of the abdominal aorta, which is in your abdomen. Aneurysms can also occur in the brain, neck or arm arteries and behind the knee cap (popliteal artery aneurysms), although all of these are less likely. The most important thing is to work with your doctor to decide if you're somebody who should be screened for aneurysms.

Aneurysms can occur in arteries in any part of the body, including the abdomen, chest, behind the knees, the brain, and arteries to various organs in the abdomen. The type of treatment depends on the aneurysm’s location and size, as well as the person's medical history.
If left unmonitored or untreated, aneurysms may rupture and cause serious health risks, including death.

n the aorta, the central artery that extends from your heart through the center of your abdomen and chest. Certain medical conditions, such as high blood pressure, can weaken the arteries, which deliver oxygenated blood from our heart to the rest of our bodies. The pressure of blood traveling through the arteries can lead to this balloon-like bulge. You can have an aneurysm for years without symptoms or problems. Others can have an aneurysm that pops, which can lead to a stroke if bleeding occurs in the brain. Ruptured aneurysms must be treated quickly, usually within minutes, or it can become deadly: about 50% of all ruptured aneurysms are fatal.
