Abdominal Aortic Aneurysm (AAA) #6, removed from a 56 year old male. Another nice image of the central channel through the ulcerated thrombus. The channel seen in the image bifurcates to the left and right iliac arteries. Dr. Nir Hus MD., PhD.
Abdominal aortic aneurysm involves a widening, stretching, or ballooning of the aorta. There are several causes of abdominal aortic aneurysm, but the most common results from atherosclerotic disease. As the aorta gets progressively larger over time there is increased chance of rupture.
