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 the formation of AAAs.

Thrombus fissuration is a worrisome sign that may point to impending rupture of an aortic aneurysm.
