PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: This is a generally well-written, informative, and
novel case report. I believe it has the potential to be a useful addition to the
literature.
REQUESTED REVISIONS: 
The following comments may help improve the manuscript:
1. The phrase in the abstract 'A total of 88% of cases were reported to occur in
men with a mean age of 54 years' repeats the one in the main text. Please re-
phrase.
2. Please provide data on arterial pressure and history of smoking of your
patient.
3. Consider reporting on true lumen residual diameter/severity of narrowing in
the true lumen according to the Sakamoto classification.
4. It would be helpful if the authors could comment on the mean SMA angle on
the initial CTA of their patient and whether it changed during follow-up.
This is because there is a school of thoughts suggesting that a larger SMA angle
is associated with a higher oscillatory shear index in the vessel lumen at the
SMA superior convex.
