Abdominal Aortic Aneurysms (Etiology, Epidemiology, and Natural History)

Anesthesiol Clin. 2022 Dec;40(4):657-669. doi: 10.1016/j.anclin.2022.08.010. Epub 2022 Sep 28.


Abdominal aortic aneurysm is a potentially lethal condition that is decreasing in frequency as tobacco use declines. The exact etiology remains unknown, but smoking and other perturbations seem to trigger an inflammatory state in the tunica media. Male sex and advanced age are clear demographic risk factors for the development of abdominal aortic aneurysms. The natural history of this disease varies, but screening remains vital as it is rarely diagnosed on physical examination, and elective repair (most commonly done endovascularly) offers significant morbidity and mortality advantages over emergent intervention for aortic rupture.
