CT in Abdominal Aortic Aneurysm


CT in Abdominal Aortic Aneurysm, AAA Computed Tomography, Helical CT in Abdominal Aortic Aneurysm, CT Angiography of Abdominal Aortic Aneurysm, Abdominal Aortic Aneurysm CTA

  • Standard Abdominal CT
  1. Indications
    1. Suboptimal Ultrasound of AAA
    2. Suspected hemodynamically stable ruptured AAA
  2. Advantages over Ultrasound
    1. Reproducible results without operator variation
    2. Defines surrounding periaortic anatomy
  3. Limitations
    1. Does not define periaortic Vascular Anatomy
  • Helical CT (Spiral CT) or CT Angiography
  1. Indications
    1. Preoperative AAA evaluation
  2. Advantages
    1. Defines periaortic Vascular Anatomy
    2. Replaces Abdominal Aortography in most cases
      1. Noninvasive detailed vascular imaging
      2. Offers three dimensional reconstruction (CTA)
