Abstract:

Extracranial-intracranial (EC-IC) bypass surgery is a commonly used technique in neurosurgery, but abnormal perfusion caused by surgical operation can lead to postoperative complications such as new-onset cerebral ischemia and neurological dysfunction, which seriously affects the prognosis of patients. Intraoperative neurophysiological monitoring (IONM) can effectively identify early intraoperative ischemia, reduce surgical complications, and assess the improvement of cerebral perfusion after the establishment of EC-IC bypass. However, no relevant norms or consensus have been developed around the world. Based on the review of reported clinical evidence, our team developed this expert consensus after Delphi expert consultation, forming a consensus on 5 aspects: the significance of IONM for EC-IC bypass surgery, the method of IONM for EC-IC bypass surgery, indications and contraindications for IONM for EC-IC bypass surgery, the monitoring strategy and interpretation of IONM results for EC-IC bypass surgery in different diseases, and other notes. Based on the GRADE evidence level standard, this expert consensus combines the national expert opinions on neurophysiology and EC-IC bypass to give eight comments on the clinical practice of IONM for EC-IC bypass surgery.

Key words: Extracranial-intracranial bypass surgery, Ischaemic cerebrovascular disease, Intraoperative neurophysiological monitoring, Complex aneurysms, Expert consensus
