Aneurisma de aorta abdominal

When Should an Abdominal Aortic Aneurysm Be Treated?
From: The Hospitalist, January 2013 by Lauren E. Carpenter, MD, and Jennifer Best, MD, FACP, FHM
"An abdominal aortic aneurysm (AAA) should be repaired when the risk of rupture outweighs the risks of surgical repair"
  1. AAA rupture is associated with significant morbidity and mortality.
  2. Risk of AAA rupture increases with size of the aneurysm, rate of growth, and female gender.
  3. Growth of AAAs is variable and affected by individual patient characteristics.
  4. Endovascular and open repair are the two surgical options for treatment of asymptomatic AAA and are comparable in long-term outcomes.
  5. Studies support ultrasound surveillance for AAA >3.0 cm; a six-month interval is recommended.
  6. Surgical repair is indicated for symptomatic AAAs or for those >5.5 cm.
