What is aneurysmal dilation

Most aneurysms come with few warnings signs until tearing or rupturing occurs. When that happens, these symptoms can emerge:. Aortic aneurysms can be confused with symptoms of a heart attack. Seeking immediate medical attention is vital if you experience any of these warning signs.

At Penn Medicine, we have two large aortic surveillance clinics — the Thoracic Aortic Program established in and our Bicuspid Aortic Valve Center established in Both programs see more than aortic surveillance patients each year.

Untreated infection, such as salmonella poisoning, is a rare cause of an aneurysm in the aorta that is commonly known as a mycotic aneurysm. People with problems of the aortic valve may be more likely to experience ascending aortic aneurysms. For example, those born with a bicuspid aortic valve — where there are just 2, rather than 3, cusps of the aortic valve — may experience more pressure on the artery walls.

Aneurysms that develop in the chest area, above the diaphragm, are classed as thoracic aneurysms and may be subcategorized as either ascending or descending. Descending aortic aneurysms occur in the back of the chest cavity. Aneurysms that develop in the lower part of the aorta are called abdominal aortic aneurysms.

These are more common than thoracic aortic aneurysms, with abdominal aortic aneurysms comprising over 75 percent of aortic aneurysms. An ascending aortic aneurysm is a serious health risk. It may rupture, causing internal bleeding that can be life-threatening.

The larger the aneurysm, the greater the risk of rupture. Similarly, larger aneurysms can cause aortic dissection, a life-threatening medical emergency characterized by tearing of the aortic layers. If a doctor suspects an aortic aneurysm, they may use one or more of the following tests to confirm the diagnosis:. Doctors usually treat small aneurysms with beta-blockers , a type of medication for high blood pressure. In this procedure, surgeons make an incision in the chest.

They remove the damaged portion of the aorta and replace it with a synthetic tube called a graft.
