Asymptomatic TAA repair indications

Q: One of the indications of Thoracic Aortic Aneurysm (TAA) is? (select one)

A) End-diastolic aortic diameter >5.5 cm
B) End-systolic aortic diameter >5.5 cm


Answer: A

All symptomatic TAA should be repaired but major indications for the repair of TAA are
  • End-diastolic aortic diameter >5.5 cm
  • Aortic size index i.e., aortic diameter divided by body surface area ≥2.75 cm/m2
  • Aortic area over height ratio i.e., maximal aortic cross-sectional area divided by height >10 cm2/m
