Question:

What dissection is analogous to Isolated Superior Mesenteric artery dissection?
1. Renal artery dissection
2. Aortic dissection beginning at the ligamentum arteriosum
3. Vertebral artery dissection
4. Coeliac trunk dissection
5. Internal Carotid artery dissection





Answer:

The correct answer for the question "What dissection is analogous to Isolated Superior Mesenteric artery dissection?" is:

2. Aortic dissection beginning at the ligamentum arteriosum



Explanation

This segment of the SMA corresponds to the exit of the artery from the pancreas, and may be the site of acute or chronic stress due to turbulent flow in the vessel at this location, analogous to that resulting in aortic dissection at the ligamentum arteriosum

Abstract
Two cases of isolated superior mesenteric artery dissection diagnosed by contrast enhanced 64 slice CT are reported. In both, the dissection was seen extending along the entire length of the artery with one of them showing partially thrombosed false lumen. One case was associated with dissection of left renal artery with consequent renal infarcts. Although superior mesenteric artery dissection is a rare phenomenon, it should be considered in the differential diagnosis of abdominal angina.
