Study Notes
Abdominal Aortic Aneurysm (AAA)
Symptoms
- Asymptomatic in most cases
- May cause:
- Abdominal pain or discomfort
- Back pain
- Abdominal tenderness
- Nausea and vomiting
- Loss of appetite
- Rupture symptoms:
- Sudden, severe abdominal pain
- Hypotension
- Tachycardia
- Abdominal distension
- Peritoneal signs (guarding, rebound tenderness)
Diagnosis
- Imaging studies:
- Ultrasound (US)
- Computed Tomography (CT) scan
- Magnetic Resonance Angiography (MRA)
- Diagnostic criteria:
- Aortic diameter ≥ 3 cm
- Aortic diameter ≥ 1.5 times the normal diameter
Treatment Options
-
Endovascular Aneurysm Repair (EVAR):
- Minimally invasive procedure
- Stent-graft placement to exclude the aneurysm
-
Open Surgical Repair:
- Open surgical procedure
- Aneurysm resection and graft replacement
-
Watchful Waiting:
- Monitoring with regular imaging studies
- Intervention if aneurysm grows or symptoms develop
Risk Factors
- Age: ≥ 65 years
- Male gender
- Family history of AAA
- Smoking
- Hypertension
- Atherosclerosis
- High cholesterol
Screening
-
USG screening recommended for:
- Men ≥ 65 years with a history of smoking
- Men ≥ 60 years with a family history of AAA
- One-time screening for AAA between 65-75 years
- Interval screening every 5 years for individuals with a normal USG result

Watchful Waiting
- Monitoring with regular imaging studies, with intervention if aneurysm grows or symptoms develop
Risk Factors
- Age ≥ 65 years
- Male gender
- Family history of AAA
- Smoking
- Hypertension
- Atherosclerosis
- High cholesterol
Screening
- Ultrasound screening recommended for men ≥ 65 years with a history of smoking and men ≥ 60 years with a family history of AAA
