What does the microsurgical aneurysm clipping procedure involve?
This is an open craniotomy performed under general anesthesia. The surgeon makes a small opening in the skull, uses a microscope to locate the aneurysm, and places a small titanium clip across its neck to block blood flow into the aneurysm sac. The clip remains permanently in place, and the bone flap is reattached. The procedure typically takes 2–4 hours.
