Craniotomy to Treat Aneurysms: Patients suffering from conditions within the skull, like aneurysms, require a craniotomy.
Not all aneurysms require immediate treatment. Very small (less than 3 mm) aneurysms are less likely to break or rupture; thus, may not need immediate treatment.
A surgeon may decide to treat an aneurysm, even when it does not show any symptoms, in order to prevent the possibility of a fatal rupture in the future. Surgery may involve coiling or clipping and is used to treat both ruptured and unruptured aneurysms. This is one of the most commonly used methods for repairing aneurysms.
Surgical clipping is performed through a craniotomy. A craniotomy is a surgical procedure that allows access to the brain and blood vessels inside the head via an opening in the skull. Once the aneurysm itself is clearly identified, a small metal clip is applied to it. This eliminates the risk of this an aneurysm from bleeding in the future.
Endovascular surgery often uses a “coil” or coiling to repair aneurysms. This is a less invasive way to treat certain aneurysms.
