Question: Craniotomy

 Frances Hill - Sun May 31, 2009 10:04 am

My mom is scheduled for a craniotomy for a cerebral aneurysm clipping after a failed attempt to complete an angiographic coiling. She wants to know if the arteries in the brain in the prefrontal lobe are on the surface of the brain or deeper in the brain tissue? And what is the average length of time for this surgery?

User avatar Hi Frances Hill,
The circle of Willis whose branches supply the brain are on its under surface - thus, although they are superficial to the brain,they are situated under the brain.Do not worry about the time taken to complete the procedure, It is surgeon dependent and in modern era, does not matter much(thanks to modern anesthetic practices).
