- Fig 1.
Large pericallosal aneurysm treated with Neuroform stent and coils. Frontal (A) and lateral (B) angiograms showing large wide-necked pericallosal aneurysm. Native lateral projection (C) image showing placement of Neuroform stent across the aneurysm neck. D, Subsequent placement of coils within the aneurysm is well constrained by the stent. Final frontal (E) and lateral (F) angiograms showing the coiled pericallosal aneurysm. At the conclusion of the case, thrombus was noted in 1 of the MCA branches, presumably related to thrombus from the guide catheter.

(A) Noncontrast CT, contrast-enhanced CT, and axial CTA images showing a large partially thrombosed AcomA aneurysm. Frontal oblique angiograms showing the aneurysm before (B) and after (C, D) treatment. Eighteen-month follow-up MRA sequential source images (E-H) and maximum intensity projection (I) show stent widely patent and resolution of the aneurysm thrombus. The area of signal intensity dropout in the A1 segment was stable in the immediate postoperative and other follow-up MRAs and was related to artifact from the end markers on the stent.
