Abdominal Aortic Aneurysm

What is Abdominal Aortic Aneurysm (AAA)?

The aorta is the most significant blood vessel in the body. Its thickness is similar to a garden hose. This vessel is responsible for carrying blood from the heart to the head, and arms, as well as down through the abdomen and pelvis to the legs. An abdominal aortic aneurysm is a condition in which the part of the aorta that travels through the abdomen has weakened. The walls of the aorta become extended like a balloon as a result of weakness in the vessel wall.

Symptoms of Abdominal Aortic Aneurysm

An abdominal aortic aneurysm may grow over time without causing initial symptoms. This aneurysm may never rupture and may always stay small. Sometimes, the abdominal aortic aneurysm expands more quickly. The rate of expansion is not something that we can predict.

If the aneurysm grows larger, symptoms such as deep, persistent pain in the abdomen, back pain, or a pulsating or vibrating sensation near the navel may develop. The sudden onset of any of these symptoms requires emergency medical care.

Science has not determined an exact cause of abdominal aortic aneurysm. However, there are several contributing factors. These include:

  • High blood pressure, which can weaken the walls of the aorta.
  • Atherosclerosis, or hardening of the arteries, fills the lining of the blood vessel with fatty substances.
  • Vascular disease in the aorta, which cause inflammation.
  • Infection in the aorta caused by fungus or bacteria.
  • Trauma to the chest or abdominal cavity, such as an auto accident.
  • Tobacco use, which can weaken the walls of the aorta.
  • Heredity.

diagnosing Abdominal Aortic Aneurysm

Many abdominal aortic aneurysms are detected during a medical examination conducted for other reasons. For instance, a general physical exam may reveal an abdominal bulge. This type of aneurysm may also be detected during medical tests such as chest x-ray or abdominal ultrasound.

If symptoms, examination findings, or medical history indicate a potential abdominal aortic aneurysm, your doctor may order specialized tests. These include:

  • Abdominal ultrasound. This non-invasive, painless imaging exam is conducted in a radiology facility or hospital. After applying gel to the abdomen, the provider runs a transducer across the skin. This sends ultrasound waves into the abdominal cavity, which will bounce off of structures to produce an image that is displayed on the computer monitor.
  • CT scan. Computerized tomography, or CT, is conducted in a donut-shaped machine. The patient lies comfortably on an exam table, and the table is moved through the machine as cross-sectional images are captured.
  • MRI, or magnetic resonance imaging, can detect the size and location of an aneurysm. This test is somewhat similar to a CT scan, but the tube-like machine is longer. The table slides into the machine and remains in place throughout the test. The doctor obtains images using a magnetic field and radio wave energy.

Abdominal Aortic Aneurysm Risk Factors

Doctors are careful to monitor or treat abdominal aortic aneurysm to diminish the risk of complications. The primary complication to avoid is aneurysm rupture, in which the “balloon” of weakened aortic tissue breaks open, allowing extensive internal bleeding. Another complication that may occur includes aortic dissection, or tears in the layers of the aortic wall. Finally, blood clots may form around the aortic aneurysm. If one or more blood clots break free, it can create a blockage in any blood vessel of the body.

Treatment for Abdominal Aortic Aneurysm

An abdominal aortic aneurysm may be treated with one of two surgical techniques:

  • Open abdominal surgery involves an incision on the abdomen to gain access to the interior space. The damaged section of the aorta is located and removed. A synthetic graft tube is inserted in the place of this section. It is secured with sutures.
  • Endovascular aneurysm repair is a technique that involves small incisions in the groin, through which a graft stent is inserted. This stent is situated within the aneurysm to preserve blood flow and prevent aneurysm rupture. No aortic tissue is removed in this surgical procedure.

Recovery after Surgery for AAA

Regardless of the type of surgery performed for AAA, the patient may remain in the hospital for a few days. At home, recovery may continue at a relatively slow pace. Soreness at the incision site of an open AAA repair diminishes gradually over 5 to 10 days. Discomfort after either surgical technique is manageable with prescription pain medication. Patients should expect to feel more fatigued than usual during their recovery. Rest and a good support system are vital to healing and general well-being. After 6 to 8 weeks, patients will be more comfortable and can resume more activities.
