This video details the microsurgical clipping of a complex, partially calcified, unruptured left posterior inferior cerebellar artery (PICA) aneurysm. After discussion of the clinical presentation, the relevant anatomy is reviewed and the role of imaging, including MRI/MRA and digital subtraction angiography, in preoperative evaluation is explained. The video then documents the entire procedure step by step, illustrating clip placement and highlighting measures to ensure a successful outcome, including the use of intraoperative angiography to confirm complete occlusion of the aneurysm.

Video Transcript

[MUSIC PLAYING] Here, we describe the microsurgical clipping of the complex PICA aneurysm. This aneurysm was diagnosed in a 65-year-old woman who presented to the emergency with headache and some dizziness. After discussion of treatment versus observation, we decided for treatment.

The aneurysm is large and, therefore, we temporary clip, under burst suppression, the vertebral artery. Once the first clip is positioned, we check, confirm the patency of the distal vertebral artery. Once we are sure, we add another clip on top of the first one. After final dissection around the dome, we add a third clip as a final booster clip to completely eliminate the flow in the aneurysm.
