Summary

Intraoperative indocyanine green (ICG) videoangiography is now widely used in aneurysm surgery because of its reliability and safety. ICG videoangiography is able to evaluate patency of parent, branching and perforating arteries and documents clip occlusion of aneurysms. False interpretation of ICG videoangiography may occur when viewing aneurysms and arteries located deep in the visual field. The authors present a case of unruptured large left middle cerebral artery aneurysm in a 65-year-old woman in whom ICG videoangiography wrongly displayed clip occlusion of the aneurysm. ICG videoangiography confirmed blood flow in parent, branching and perforating arteries, the sac behind the clip did not fill with contrast. Fundus puncture caused bleeding and, consequently, contrast material occurred in the sac. We added more clips (totalling five) and we succeeded to stem the inflow of blood into the sac. The authors emphasize the need for opening the sac after clipping. Full reliance on ICG videoangiography could lead to erroneous aneurysm treatment with an uncertain long‑term result.

Key words:
intracranial aneurysms – clipping – indocyanine green – videoangiography
