Keyhole Microsurgery for Cerebral Aneurysms

Abstract

The choice of an effective and safe surgical approach is an important and largely outcome-determining step in the microsurgical treatment of cerebral aneurysms. Transcranial approach to aneurysm should provide proximal and distal control, visualization of the aneurysm and surrounding structures, freedom to work with microinstruments, optimal and close view of the surgical field with the necessary ergonomics and the possibility of comfortable work for the neurosurgeon. In addition, the approach should provide a low risk of associated complications, good cosmetic outcomes and patient satisfaction. Today, a neurosurgeon has a sufficient number of approaches to cerebral aneurysms. Minimally invasive approaches are the reduced model of traditional approaches and each of these approaches has a specific surgical corridor that cannot be changed during microsurgical manipulations, unless through the transition to an extended craniotomy.
