What is Abdominal Aortic Aneurysm Surgery?

An abdominal aortic aneurysm (AAA) is a localized dilation of the infrarenal abdominal aorta to a diameter greater than 3 cm; rupture risk increases sharply at diameters of 5.5 cm or more.

Repair is indicated when the aneurysm reaches 5.5 cm in men or 5.0 cm in women, grows more than 1 cm per year, becomes symptomatic, or ruptures.

Endovascular aneurysm repair (EVAR) is the first-line technique in suitable anatomy, while open transabdominal repair remains the standard for younger fit patients, complex anatomy, or ruptured aneurysms when EVAR is not feasible.

Symptoms

Asymptomatic in most cases — detected by abdominal ultrasound screening or imaging for other reasons
Pulsatile abdominal mass on examination
Deep boring abdominal, flank, or back pain
Sudden severe abdominal or back pain with hypotension — possible rupture (life-threatening)
Distal embolization causing limb ischemia or 'blue toe' syndrome

Risk Factors

Male sex and age over 65
Smoking — the strongest modifiable risk factor
Hypertension and atherosclerotic disease
Family history of abdominal aortic aneurysm
Connective tissue disorders such as Marfan or Ehlers-Danlos syndromes

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Pulsatile abdominal mass detected on examination or imaging
  • Aneurysm 5.5 cm or larger in men, 5.0 cm or larger in women
  • Aneurysm growth more than 1 cm per year
  • Sudden severe abdominal or back pain — emergency evaluation for rupture

Treatment Methods

01
Surveillance with ultrasound or CT every 6 to 12 months for small aneurysms below repair threshold
02
Smoking cessation, blood pressure control, and atherosclerosis risk factor management
03
Endovascular aneurysm repair (EVAR) using a stent graft in suitable anatomy
04
Open surgical repair with aortobifemoral or aortoaortic graft in patients with anatomy unsuitable for EVAR or rupture
05
Long-term postoperative imaging follow-up to detect endoleaks, graft migration, and aneurysm sac changes
