Abdominal Aortic Aneurysm (AAA)

What Is an Abdominal Aortic Aneurysm?

An Abdominal Aortic Aneurysm (AAA) is a localised enlargement or bulging of the aorta, the main blood vessel that carries blood from the heart through the chest and abdomen.

​

Over time, the weakened section of the aortic wall can expand. If the aneurysm continues to grow, there is a risk of rupture, which is a life-threatening medical emergency.



Causes, Symptoms & TreatmentWhat Causes AAA?

AAAs develop due to weakening of the aortic wall. Contributing factors include:

  • Smoking

  • High blood pressure (hypertension)

  • Atherosclerosis (build-up of plaque in the arteries)

  • Genetic predisposition or family history


Symptoms

In many cases, AAAs do not cause symptoms in their early stages and are often detected incidentally.

When symptoms do occur, they may include:

  • A deep, persistent, or pulsating pain in the abdomen

  • Lower back pain

 

A ruptured aneurysm is a medical emergency and may present with:

  • Suddenly, severe abdominal or back pain

  • Dizziness or collapse

  • Nausea and sweating

 

Treatment Options

Management depends on the size of the aneurysm and the risk of rupture. When an aneurysm reaches a size where the risk becomes significant, intervention is recommended.


Endovascular Aneurysm Repair (EVAR)

EVAR is a minimally invasive procedure used to treat AAAs and is often preferred over traditional open surgery where appropriate.

 

Benefits of EVAR include:

  • Smaller incisions (typically in the groin)

  • Shorter hospital stay and faster recovery

  • Reduced postoperative pain

  • Lower overall procedural risk in suitable patients

 

Overview of the EVAR Procedure

  • Access: Small incisions are made in the groin, and thin tubes (catheters) are inserted into the arteries.

  • Deployment: A stent-graft (a fabric-covered metal mesh tube) is guided through the blood vessels to the site of the aneurysm.

  • Positioning: The stent-graft is carefully positioned and expanded within the aorta, sealing off the weakened area and redirecting blood flow through the graft.

  • Closure: The catheters are removed, and the small incisions are closed.

 

Recovery & Follow-Up

Recovery following EVAR is typically faster than with open surgery. Many patients are discharged within 24–48 hours, depending on their overall health.

Regular follow-up imaging is essential to:

  • Monitor the position of the stent-graft

  • Ensure the aneurysm remains sealed

  • Detect any potential complications early
