==Overview==
==Overview==
An [[aneurysm]] is a localized bulge or balloon in the wall of an artery, or in most cases in the aorta (the major blood vessel that supplies blood to the body). Abdominal aortic aneurysms occur in the part of the aorta running through the abdomen, if the aneurysm ruptures it can cause life-threatening bleeding.

Abdominal aortic aneurysms occur in the part of the [[aorta]] running through the abdomen, if the aneurysm ruptures it can cause life-threatening bleeding.  
Because aneurysms can develop and become large before causing any symptoms, it is important to look for them in people who are at high risk. Most small abdominal aortic aneurysms do not rupture, but the large aneurysms have a higher risk of a rupture. Ultrasound screening for abdominal aortic aneurysms is recommended for men who have ever smoked and are between the ages of 65 and 75. Medicines and surgery are the two main treatments for aneurysms.

When an abdominal aortic aneurysm ruptures, it is a true medical emergency. [[Aortic dissection]] occurs when the innermost lining of the artery tears and blood leaks into the wall of the artery. This most commonly occurs in the aorta within the chest.

*[[Arterial embolism]]
* Pulsating sensation in the [[abdomen]]
*[[Heart attack]]
* Stiff or rigid [[abdomen]]
*[[Hypovolemic shock]]
 
*[[Kidney failure]]
You may have an abdominal aortic aneurysm that is not causing any symptoms or problems. Your doctor may find this problem by doing the following tests:
*[[Stroke]]
* [[Angiogram]]
* [[CT]] scan of the abdomen -- to confirm the size of the aneurysm
* [[Ultrasound]] of the abdomen -- done when an abdominal aneurysm is first suspected

Overview

An aneurysm is a localized bulge or balloon in the wall of an artery, or in most cases in the aorta (the major blood vessel that supplies blood to the body). Abdominal aortic aneurysms occur in the part of the aorta running through the abdomen, if the aneurysm ruptures it can cause life-threatening bleeding. Because aneurysms can develop and become large before causing any symptoms, it is important to look for them in people who are at high risk. Most small abdominal aortic aneurysms do not rupture, but the large aneurysms have a higher risk of a rupture. Ultrasound screening for abdominal aortic aneurysms is recommended for men who have ever smoked and are between the ages of 65 and 75. Medications and surgery are the two main treatments for aneurysms.

What are the symptoms of Abdominal aortic aneurysm?

Aneurysms develop slowly over many years and often have no symptoms. If an aneurysm expands rapidly, tears open (ruptured aneurysm), or blood leaks along the wall of the vessel (aortic dissection), symptoms may develop suddenly. As the aneurysm grows, some symptoms may be:

What causes Abdominal aortic aneurysm?

The exact cause is unknown, but risk factors for developing an aortic aneurysm include:

Who is at highest risk?

An abdominal aortic aneurysm can develop in anyone, but is most often seen in males over 60 who have one or more risk factors. The larger the aneurysm, the more likely it is to rupture and break open.

Diagnosis

Your doctor will examine your abdomen. The exam also will include an evaluation of pulses in your legs. The doctor may find:

You may have an abdominal aortic aneurysm that is not causing any symptoms or problems. Your doctor may find this problem by doing the following tests:

  • Angiogram
  • CT scan of the abdomen -- to confirm the size of the aneurysm
  • Ultrasound of the abdomen -- done when an abdominal aneurysm is first suspected

Any one of these tests may be done when you're having symptoms.

When to seek urgent medical care?

Go to the emergency room or call 911 if you have pain in your belly or back that does not go away or is very bad.

Treatment options

If you have bleeding inside your body from an aortic aneurysm, you will have open abdominal aortic aneurysm repair. If the aneurysm is small and there are no symptoms:

  • You and your doctor must decide whether the risk of having surgery is smaller than the risk of bleeding if you do not have surgery.
  • Your doctor may recommend checking the size of the aneurysm with a yearly ultrasound test, to see if the aneurysm is getting bigger.

Surgery is usually recommended for patients who have aneurysms bigger than 2 inches or 5.5 cm across and aneurysms that are growing quickly. The goal is to perform surgery before complications or symptoms develop. There are two approaches to surgery:

  • In a traditional (open) repair, a large cut is made in your abdomen. The abnormal vessel is replaced with a graft made of man-made material, such as Dacron.
  • The other approach is called endovascular stent grafting. This procedure can be done without making a large cut in your abdomen, so you may get well faster. Endovascular repair is rarely done for a leaking or bleeding aneurysm.

Prevention of Abdominal aortic aneurysm

To reduce the risk of developing aneurysms:

  • Eat a heart-healthy diet, exercise, stop smoking (if you smoke), and reduce stress to help lower your chances of having a blocked artery again.
  • Your health care provider may give you medicine to help lower your cholesterol.
  • If you were given medicines for blood pressure or diabetes, take them as your doctor has asked you to.

People over age 65 who have smoked at any time in their life should have a screening ultrasound performed once.

What to expect (Outlook/Prognosis)?

The outcome is usually good if an experienced surgeon repairs the aneurysm before it ruptures. However, less than 40% of patients survive a ruptured abdominal aneurysm.

Possible complications

When an abdominal aortic aneurysm ruptures, it is a true medical emergency. Aortic dissection occurs when the innermost lining of the artery tears and blood leaks into the wall of the artery. This most commonly occurs in the aorta within the chest. Complications include:
