Abstract:
The luminal separation of the vessel into two distinct, parallel channels that reunite distantly is known as fenestration. There is a correlation between the development of an aneurysm and the proximal portion of fenestration, although fenestrations are typically regarded as a variant of normal anatomy. We report an interesting case of an anterior communicating artery (a-comm) aneurysm, which turns out to be a ruptured fenestrated A1 segment aneurysm after digital subtraction angiography with concomitant multiple aneurysms treated by clipping along with case report and literature review.
