Mesenteric angiography via the coeliac axis and SMA confirms the presence of a false aneurysm arising from a small proximal branch of the SMA. No filling from the coeliac axis was demonstrated. The false aneurysm corresponds in position to the false aneurysm identified on the CT scan.
Using a Simmons 2 catheter as a guide in the SMA, a Progreat microcatheter was manipulated as far as the false aneurysm. From there it was possible to fill the false aneurysm and occlude the feeding vessel using 5 mm fibred straight 0.018 inch micro coils. Final runs demonstrate no filling of the false aneurysm and no compromise to adjacent SMA branches.
