What is an Aortic Aneurysm?

An aortic aneurysm is a bulge or dilation in the wall of the aorta, the largest artery in the body. The aorta carries oxygen-rich blood from the heart to the rest of the body. When a section of the aorta becomes weakened, it can enlarge, posing a risk of rupture, which can be life-threatening.

Types of Aortic Aneurysms

There are two main types of aortic aneurysms:

1. Thoracic Aortic Aneurysm (TAA):
   • Occurs in the chest area.
   • Can affect the ascending aorta, aortic arch, or descending aorta.
2. Abdominal Aortic Aneurysm (AAA):
   • Develops in the lower part of the aorta, in the abdomen.
   • More common than thoracic aneurysms.

Symptoms of Aortic Aneurysms

Aortic aneurysms often grow slowly and may not cause symptoms until they are large or rupture. Symptoms can vary depending on the type and location but may include:

• For Thoracic Aortic Aneurysms:
  • Chest pain or back pain.
  • Shortness of breath or difficulty swallowing.
  • Hoarseness.
• For Abdominal Aortic Aneurysms:
  • Deep, constant pain in the abdomen or lower back.
  • A pulsating sensation near the navel.
  • Sudden, severe pain if the aneurysm ruptures.

Causes and Risk Factors

Aortic aneurysms can result from several factors, including:

1. Atherosclerosis:
   • The buildup of plaque in the artery walls weakens the aorta.
2. Genetic Conditions:
   • Conditions like Marfan syndrome, Ehlers-Danlos syndrome, or other connective tissue disorders can increase the risk.
3. Age and Gender:
   • More common in people over 65, with men at higher risk.
4. Lifestyle Factors:
   • Smoking, high blood pressure, and high cholesterol levels are significant contributors.
5. Infections or Injuries:
   • Rarely, infections or trauma can lead to an aneurysm.

Diagnosis

Diagnosing an aortic aneurysm often begins with a physical examination and imaging tests to confirm its presence and size:

1. Ultrasound:
   • Commonly used to screen for abdominal aortic aneurysms.
2. CT Scan or MRI:
   • Provides detailed images to assess the size, location, and risk of rupture.
3. X-Ray:
   • May detect signs of a thoracic aneurysm.

Treatment Options

Treatment depends on the size and growth rate of the aneurysm as well as the patient’s overall health:

1. Monitoring:
   • Small, slow-growing aneurysms are often monitored with regular imaging tests and lifestyle changes to control risk factors.
2. Surgical Intervention:
   • Open Repair: The damaged section of the aorta is replaced with a synthetic graft.
   • Endovascular Repair (EVAR/TEVAR): A minimally invasive procedure where a stent graft is inserted through a small incision to reinforce the aorta.

Prevention and Lifestyle Changes

To reduce the risk of developing an aortic aneurysm or its complications, consider:

• Quitting smoking.
• Maintaining healthy blood pressure and cholesterol levels.
• Regular exercise and a balanced diet.
• Routine screenings, especially if there is a family history or other risk factors.
