Aortic Aneurysm

Aortic aneurysms are bulges that occur in the wall of the aorta, the main artery from the heart. These aneurysms can form in any part of the aorta, but they are most commonly found in the abdominal area. Aortic aneurysms can be life-threatening if they rupture, leading to internal bleeding or blocking blood flow from the heart to other organs.

Here are some key points about aortic aneurysms:

·      An aneurysm forms in a weak area in the artery wall due to the pressure of blood pumping through the artery.

·      Aortic aneurysms can be classified based on their location:

1.  Thoracic Aortic Aneurysms (TAA): These occur in the portion of the aorta that runs through the chest.

2.  Abdominal Aortic Aneurysms (AAA): These occur in the portion of the aorta that passes through the abdomen.

·      AAAs are more common in men and people assigned male at birth than in women and people assigned female at birth. They affect only about 1% of men aged 55 to 64 and become more common with increasing age.

·      TAAs are equally likely to occur in men and women and become more common with increasing age.

Risk Factors for Aortic Aneurysms

Several factors can increase the risk of developing an aortic aneurysm or experiencing a rupture, including:

  • Age
  • Gender
  • Family history
  • Smoking
  • High blood pressure
  • High cholesterol
  • Inherited connective tissue disorders

Causes of aortic aneurysm

The causes of an aortic aneurysm are unknown, however, they can include:

  • Atherosclerosis
  • High blood pressure
  • Infection
  • Trauma
  • Genetic factors

Symptoms of aortic aneurysm

Many aortic aneurysms do not cause any symptoms until they rupture.

  • Symptoms of a ruptured aneurysm include:
    • Sudden, severe abdominal or back pain
    • Rapid heartbeat
    • Clamminess, dizziness, or nausea
    • Shock
  • Symptoms of an unruptured aneurysm include:
    • Abdominal or back pain
    • A pulsating sensation in the abdomen
    • Clamminess, dizziness, or nausea

Complications of Aortic Aneurysms

If left untreated, aortic aneurysms can lead to severe complications, including:

  • Rupture: A ruptured aortic aneurysm causes life-threatening internal bleeding and requires emergency medical attention.
  • Dissection: Aortic dissection occurs when the layers of the aortic wall separate. Thus, leading to a tear in the wall of the artery. This can lead to organ damage or death if not promptly treated.
  • Organ Dysfunction: Aortic aneurysms can compress nearby organs or blood vessels, leading to organ dysfunction or failure.

How is an aortic aneurysm treated?

Treatment of aortic aneurysms depends on several factors, including:

·      the size and location of the aneurysm

·      the patient’s overall health

·      the presence of any symptoms.

Treatment options include:

·       Medications to lower blood pressure, improve blood flow or manage cholesterol

·       Lifestyle changes, such as quitting smoking and eating a healthy diet

·       Surgery, including open repair and endovascular repair

Recovery after aortic aneurysm surgery can take several weeks or months. Possible complications after surgery include:

  • Bleeding
  • Infection
  • Blood clots
  • Heart attack
  • Stroke

Preventing aortic aneurysms involves maintaining a healthy lifestyle, including:

  • Quitting smoking
  • Eating a healthy diet
  • Exercising regularly
  • Managing high blood pressure and high cholesterol
  • Avoiding stimulating drugs like cocaine
