Craniotomy for Brain Tumors

A craniotomy is a procedure to remove a lesion in the brain through an opening in the skull (cranium). A craniotomy is a type of brain surgery and is the most commonly performed surgery for brain tumor removal.

It also may be done to remove a blood clot (hematoma), to control hemorrhage from a weak, leaking blood vessel (cerebral aneurysm), to repair arteriovenous malformations (abnormal connections of blood vessels), to drain a brain abscess, to relieve pressure inside the skull, or to perform a biopsy.The procedure is engaged through a glioma resection with fluorescence guidance in high-grade tumors, neuronavigation and functional mapping.

Through the administration of ALA preoperatively, tumoral cells in high-grade gliomas are able to synthetize a fluorescent substance that can be visually detected with the help of a specially designed light, which enables the surgeon to differentiate between red colored tumoral tissue from blue normal brain parenquima.

Without this technology is difficult to define the resection limits of some infiltrative tumors.
