Intraoperative monitoring by imaging and electrophysiological techniques during giant intracranial aneurysm surgery Contrôle peropératoire par les techniques d'imagerie et d'électrophysiologie lors de la chirurgie des anévrismes géants intracrâniens

Difficulties in giant intracranial aneurysm surgery are the consequence of aneurysmal wall histology and the complex angioarchitecture of the vascular tree. In order to reduce complications and risks of those procedures, various imaging and electrophysiological techniques can be implemented perioperatively. The authors review the principles, goals and main results in this context of micro-Doppler and flowmeter techniques, near-infrared spectroscopy, operative microscope-integrated indocyanine green video-angiography, neuro-endoscopy, selective intraoperative angiography and electrophysiological monitoring. © 2015 Published by Elsevier Masson SAS.
