What is a Abdominal Aortic Aneurysm (AAA)?
Your doctor may recommend abdominal aortic aneurysm (AAA) repair to treat an aneurysm. An aneurysm is a bulging, weak spot in the aorta that may be at risk for rupturing. In this case, the aneurysm is in part of the aorta that is in the abdomen. Repair of an AAA may be done in one of two ways:
- Open repair. For this surgery, your doctor makes a large incision in the abdomen to expose the aorta. Once he or she has opened the abdomen, a graft can be used to repair the aneurysm. Open repair remains the standard procedure for an abdominal aortic aneurysm repair.
- Endovascular aneurysm repair (EVAR). This is a minimally invasive option. This means it is done without a large incision. Instead, the doctor makes a small incision in the groin. He or she will insert special instruments through a catheter in an artery in the groin and thread them up to the aneurysm. At the aneurysm, your doctor will place the stent and graft to support the aneurysm.
Who should get this test?
Ultrasound of Abdominal Aortic Aneurysm (AAA) is usually ordered by doctors for the following reasons:
- To prevent the risk of rupture
- To relieve symptoms
- To restore a good blood flow
- Size of aneurysm greater than 5 centimeters in diameter (about 2 inches)
- Growth rate of aneurysm of more than 0.5 centimeter (about 0.2 inch) over 1 year
- When risk of rupture outweighs the risk of surgery
- Emergency life-threatening bleeding
Is there radiation involved?
No. Unlike X-ray imaging, there is no ionizing radiation exposure associated with ultrasound imaging.
