Perforating Artery Injury during Microsurgery for Internal Carotid Artery Bifurcation Aneurysms

2015 
: Internal carotid artery bifurcation aneurysms(ICB-ANs)are relatively rare and are difficult to occlude by direct clipping without perforating artery injury(PAI). We retrospectively analyzed 11 aneurysms in 10 cases. PAI was identified in 5 of 10 cases on postoperative computed tomography(CT)or magnetic resonance imaging(MRI), and 2 of these patients were symptomatic. PAIs were distributed in the caudate nucleus and/or the genu of the internal capsule. PAI occurred in 3 of 5 cases in which indocyanine green videoangiography(ICG-VAG)was performed. ICG-VAG is a helpful tool visualizing blood flow of vessels in surgical fields. However, PAI is a potential risk in direct clipping of ICB-ANs even if adjacent perforating arteries were observed using ICG-VAG.
