| ABSTRACT |
|
A rare case of ruptured aneurysm associated with multiple A1 fenestrations resembling plexiform network was demonstrated by 3D angiography. A 56-year-old female presented with a ruptured aneurysm in the A2 segment of the left distal anterior cerebral artery associated with the right A1 fenestration. The ruptured aneurysm was occluded with surgical neck clipping via interhemispheric approach without neurological deficit. Plexiform fenestrations of the right distal A1, opposite side to the left ruptured A2 aneurysm, were clearly visible on postoperative 3D angiography. Our case may strongly support the theory described by Paget, namely that a remnant of the plexiform anastomosis between the primitive olfactory artery and A1 segment is the source of such fenestration. |
