so i'm lead to believe,  most aortic anuerysms are eccentric rather than truly saccular, or fusiform for that matter...

Thanks Patricia.

I set Jonathan Nguyen to the task of asking him (Dr. Polak). Clearly the Bat Phone to Commissioner Gordon is on your desk, not Jon’s.

This is from Dr. Polak:

 

This is to clearly distinguish saccular aneurysms from other types of aneurysms.

 

Sonographers may be tempted to call an aneurysm saccular if the aorta is dilated in an "eccentric fashion" (not evenly) and when the term fusiform (evenly dilated) does not apply. The implications are different.

 

1. an eccentric aneurysm places more stress on one wall than on another.  It may grow more quickly but the risks of rupture are likely a function of size.

 

2. a saccular aneurysm represents another etiology, most often infectious or inflammatory.  The three layers of the aortic wall tend not to be intact.  It requires very close monitoring at the very least.  The risk of rupture/dissection does not necessarily correlate with size.

 

The term "eccentric" has been extensively used in the angiographic literature and adopted for MRA and CTA.  The presence of an eccentric aneurysm may indicate an evolving saccular aneurysm but not necessarily.

No there is such a thing as an eccentric aortic aneurysm.  I wasn’t aware of this until last month when I went to the IAME vascular conference in Washington D.C and they discussed this.
