Abdominal aortic aneurysm with thrombus fissuration

  • An aneurysm is defined as a more than 50% increase in diameter compared with the expected normal diameter vessel. A less than 50% increase is termed ectasia.
  • An infrarenal aorta considered to be aneurysmal if it is 3 cm in diameter or greater. Some authors consider 3.5 cm in diameter to be a better “cut off point.”
  • Aortic wall degeneration secondary to atherosclerotic disease, as in our case, is probably not the most common cause responsible for formation of AAAs.
  • Thrombus fissuration is a worrisome sign that may point to impending rupture of an aortic aneurysm.
