Visceral Aneurysm

A visceral aneurysm is a dilation or bulge that forms within an artery to a major body organ such as the spleen, liver or kidneys. 

How does it occur?

Most are described as degenerative, in that they have formed due to weakening of the artery wall which can be caused by plaque build up, smoking, genetics or a combination of all of these factors. Some are associated with other disorders such as inflammation with blood vessels (called vasculitis). Another condition called fibromuscular dysplasia (FMD) is often found in younger female patients with aneurysms to one of the kidneys.


How can they be treated?

Generally open surgery, stenting or coiling is considered – with a preference for more minimally invasive techniques.


When should they be treated?

The current treatment guidelines proposed by the US Society for Vascular Surgery (SVS) provides the best guidelines for when these aneurysms should be treated link.
