Case Management: Abdominal Aortic Aneurysm
Contributing Author: Andres Fajardo, MD Jun 2016

AAA is a degenerative process occurring between the diaphragm and the aortic bifurcation that results in a segmental, full-thickness dilatation of the abdominal aorta exceeding the normal vessel diameter by 50 percent (i.e., ≥3.0 cm). AAAs, approximately 85 percent of which are infrarenal, are usually asymptomatic until they rupture, an often fatal event with a mortality of 85 to 90 percent. Of those patients who reach the hospital, only 50 to 70 percent survive. Read the full story & the medicine behind it.
