This document discusses the anatomy and structure of the aorta and vascular system. It then focuses on abdominal aortic aneurysms (AAA), providing details on epidemiology, risks, history, definitions, classification, morphology, and etiology. AAA affected over 700,000 people in Europe and caused approximately 10,000 deaths in the US in 2014. The document outlines the normal diameters of the abdominal aorta and iliac arteries and includes images demonstrating aneurysm anatomy.

41. • In the United States, AAA were directly responsible
for approximately 9900 deaths in 2014, and
approximately 120,000 AAA procedures were
performed to prevent
• subsequent rupture

43. HISTORY
• Egyptian mummies from 3500 years ago. The Ebers
Papyrus (c.2000 BC) clearly identifies an arterial
aneurysm, recommending, “Treat it with a knife and
burn it with a fire so that it bleeds not too much.
• John Hunter
• DeBakey , graft era .
• Juan Parodi

44. Definitions
• defined as “a permanent localized (i.e., focal)
dilatation of an artery having at least a 50% increase
in diameter compared with the expected normal
diameter of the artery in question.
• aortic aneurysms have used a 3.0-cm threshold for
definition across all adults, or a 50% increase relative
to an adjacent normal-appearing segment

45. Classification
• Site
• Aortic
• Peripheral
• True vs. pseudoaneurysm
• False trauma , iatrogenic ,anastomotic

46. • Ectasia
• Arteriomegaly
• Anerysmosis

47. Morphology
• Morphology
• Fusiform
• Saccular

48. Etiology
• Degenerative
• Inflammatory
• Dissecting
• Infectious
• Congenital
• Traumatic
