The choice of aneurysm treatment is weighed upon the aneurysm’s size, location, the risk of rupture and overall health of the patient. Although endovascular coiling is largely favored in the treatment of aneurysms, another treatment choice is a Cerebral Aneurysm Clipping. When a specialist decides on this treatment, the patient will undergo general anesthesia, and a surgeon will make an opening in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm and a small titanium clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip will remain on the artery permanently.
