title: Intraoperative assessment of anterior circulation aneurysms using the indocyanine green video angiography technique.
abstract: We performed a prospective study to evaluate the intraoperative value of indocyanine green (ICG) video angiography in anterior circulation aneurysms. From January 2007 to April 2008, 42 patients with anterior circulation aneurysms who were to undergo aneurysm clipping were enrolled in the study. Intraoperative ICG video angiography was performed using a fluorescence microscope. After the operation, three-dimensional CT angiography (CTA), digital substraction angiography (DSA) and magnetic resonance angiography (MRA) were used to evaluate the use of intraoperative ICG video angiography. Of the 42 patients, on ICG video angiography after initial clip placement, neck remnants of the aneurysm were found in two patients, inadvertent clipping of branching vessels in one patient, and inadvertent clipping of perforating vessels in two patients. ICG video angiography after adjustment of the clip position showed a perfect residual elimination with no abnormal findings. Post-operative DSA, CTA and MRA results corresponded to the intraoperative ICG video angiography findings. Therefore, ICG video angiography is an important tool to monitor residual aneurysm, parent artery stenosis or perforating artery occlusion during intracranial aneurysm clipping.
