(a) Pre-operative and (b) intra-operative angiographic images demonstrating a dissecting, partially thrombosed aneurysm with a saccular component arising from the mid portion of the right SCA, 2 cm from its origin followed by aneurysm reconstruction with preservation of distal flow

During microsurgical dissection, it was confirmed that this aneurysm was thick-walled and partially thrombosed [Figure 1a and b].
PMC3115274_02
(a) Preoperative angiographic image demonstrating an anteriorly-directed broad-based dissecting aneurysm arising from the right SCA roughly 1.5 cm beyond the SCA origin from the basilar artery. (b) Intra-operative image confirms normal flow in the SCA with obliteration of the aneurysm

The aneurysm was located 2 cm from the SCA origin, and measured 7 mm in maximal diameter [Figure 2a and b].
(a) The SCA artery, aneurysm dome, two major efferent branches, and the dissected fourth nerve running superiorly, (b) clips reconstructing the artery leaving a bulbous area at the aneurysm base to preserve flow, (c) gortex wrapping of the clipped complex
