Aortic Aneurysm

Aortic Aneurysm

An aortic aneurysm is a critical condition marked by the dilation or bulging of the aorta’s wall, the primary artery carrying blood from the heart through the chest and abdomen. This condition, largely due to atherosclerosis, hypertension, and other risk factors, can have life-threatening consequences if not properly managed.

What Causes an Aortic Aneurysm?

Factors contributing to the development of an aortic aneurysm include:

  • High blood pressure
  • Atherosclerosis, or hardening of the arteries due to plaque buildup
  • Smoking
  • Genetic conditions such as Marfan syndrome or Ehlers-Danlos syndrome
  • Physical injury
  • Aortic valve defects
  • Sometimes, the exact cause remains unknown (Idiopathic)

Symptoms of an Aortic Aneurysm

Aneurysms can remain stable or expand gradually or rapidly, often without presenting any symptoms until they reach a critical size or rupture. When symptoms do occur, they vary based on the aneurysm’s location:

  • Abdominal Aortic Aneurysm (AAA): May cause a pulsing sensation in the abdomen, abdomen or back pain, swelling of legs, and sudden leg pain with loss of movement.
  • Thoracic Aortic Aneurysm (TAA)/Thoracoabdominal Aortic Aneurysm (TAAA): Symptoms include chest pain, neck pain, altered voice quality, difficulty breathing, and similar signs as AAA.

A ruptured aneurysm is a medical emergency, indicated by sudden, intense pain, dizziness, sweating, vomiting, and possible sudden collapse.

Who is at Risk?

Aneurysms can affect anyone but are more common in:

  • Smokers
  • Individuals with a family history of aneurysms
  • Those with hypertension or high cholesterol
  • Older adults
  • People with genetic or connective tissue disorders

Diagnosing an Aortic Aneurysm

Aortic aneurysms are often detected incidentally during routine exams or imaging for other conditions. A CT angiogram is a preferred method for detailed assessment, providing information on the aneurysm’s size and effect on surrounding structures

Treatment Options

The treatment strategy depends on the aneurysm’s size, growth rate, and the patient’s overall health, including:

  • Medications: Aimed at reducing blood pressure, cholesterol levels, and preventing blood clots.
  • Surveillance: Small aneurysms are monitored with regular imaging tests to track their growth.
  • Surgery: Required for large, symptomatic, or rapidly growing aneurysms to prevent rupture.
    • Open Aneurysm Repair: Involves replacing the aneurysm segment with a synthetic graft.
    • Endovascular Stent Grafting (EVAR/FEVAR): A less invasive method using a stent-graft to reinforce the artery wall.

Prevention and Management

Managing an aortic aneurysm involves:

  • Controlling blood pressure
  • Quitting smoking
  • Regular exercise
  • Lowering cholesterol and dietary fat intake
  • Routine surveillance to monitor aneurysm growth

Aortic aneurysms, while serious, can often be effectively managed with a combination of lifestyle adjustments, medication, and, when necessary, surgical intervention. Early detection and regular monitoring are crucial to preventing complications and ensuring patient safety and well-being.
