succumbed to AAA?

38. Albert Einstein died
from an abdominal aortic
aneurysm, a type of
vascular disease that
affects more than 700,000
people in Europe.

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
