Augmented Reality in the Surgery of Cerebral Aneurysms
Augmented reality aided clipping of an unruptured, 4 mm, growing left posterior communicating artery aneurysm in a patient with a past medical history significant for the clipping of a ruptured left MCA aneurysm five years earlier and for the placement of a Pipeline stent due to neck re-growth. Before incision (00’06’’-00’34’’): The patient is settled in the supine position and her head is turned to the right. Skull exposition (00’35’’-01’05’’): The superior orbital rim, zygoma and titanium plate from a previous intervention are seen. The segmented skull images are superposed. After craniotomy (01’06’’-02’08’’): Arachnoid dissection, identification of the anterior choroidal artery, choice of clip and clip placement is guided by image injection. Note the presence of an intravascular stent in the M1 segment of the MCA from a previous endovascular intervention.
