Abdominal Aortic Aneurysm

Abdominal aortic aneurysm is a common disease that may be lethal when ruptured. A need for the repair is indicated when the aneurysm becomes greater than 5.5 cm in diameter or grows more than 0.6 cm per year. While open surgical repair has been performed safely, an endovascular approach is used in select patients if the aortic and iliac anatomy are amenable. The present review summarizes the knowledge of the pathophysiological incidence and risk, as well as current treatment strategies of AAA on the basis of current literatures.
