What to expect before, during and after an MRI scan
If you’ve never experienced a magnetic resonance imaging (MRI) scan before, you might be anxious about what to expect.
The aorta is the body's largest blood vessel. If a section of this large artery forms an aneurysm (has damage) and ruptures, you will have life-threatening internal bleeding. If the weakened area is large, the risk of rupture is greater.
When an aortic aneurysm is detected before a problem develops, physicians will monitor its growth. If they determine that it is rapidly growing or large enough, they may decide to treat it surgically or with stent grafting.
Aortic aneurysms most often occur in the abdomen as an abdominal aortic aneurysm, but can also occur in the upper chest as a thoracic aortic aneurysm.
Types of Aortic Aneurysms
While the exact cause is unclear, an aortic aneurysm may be caused by multiple factors that damage the aortic wall. Atherosclerosis (hardening of the arteries) is thought to play an important role. Infection, injury to the aorta and genetic disorders, including Marfan syndrome, are also factors that increase the risk of developing an aortic aneurysm.
Other risk factors that contribute to aortic aneurysm include:
Many of these risk factors can be reduced or eliminated by changing your lifestyle. Medical professionals recommend that men older than 60 who have ever smoked should have a one-time screening for abdominal aortic aneurysm with a simple ultrasound test.
Symptoms of a growing aortic aneurysm can include pain in the abdominal area, groin or lower back. Many aortic aneurysms are asymptomatic, meaning that the patient often does not experience noticeable symptoms prior to the detection that an aortic aneurysm is present.
When to see a doctor
You should see a doctor if you have any of the symptoms listed above. If you are a male and a smoker, there is an increased risk of aortic aneurysm.
There isn't enough evidence to determine whether women ages 65 to 75 who have ever smoked cigarettes or have a family history of abdominal aortic aneurysm would benefit from abdominal aortic aneurysm screening. If you are showing signs of common risk factors associated with aortic aneurysm, ask your doctor if you need to have an ultrasound screening. Women who have never smoked generally don't need to be screened for the condition.
When an aortic aneurysm is detected, it is usually incidental during an examination for another condition. Tests to confirm the presence of an aortic aneurysm include:
Treatment of an aortic aneurysm depends on its size and the symptoms an individual may be experiencing. The goal is to prevent the aneurysm from ever rupturing. Medication to control high blood pressure and to lower cholesterol may be prescribed. Surgery may also be indicated.
There are generally two types of aneurysm repair surgeries:
A ruptured aneurysm is a very dangerous condition. Although it is possible to repair a ruptured aneurysm surgically, it is important to identify and treat aneurysms before a rupture occurs.
