SURGICAL APPROACHES OF THE CORPUS-CALLOSU M

There are no dedicated approaches to the corps callosum itself. The di fferent approaches, subcallosal, supracallosal and posterior to the sp lenium are usually used to reach neighboring structures such as third ventricle or pericallosal arteries. MRI is the best guideline to reach a specific position in the corps callosum and must imperatively contr ibute to the choice of the type of approach. During the procedure, it is necessary to take great care to protect the vessels, arteries and v eins especially, to avoid ischemic damage which is the main complicati on of these approaches.
