To investigate the clinical efficacy of carotid endarterectomy under multimodal monitoring in the treatment of severe internal carotid artery stenosis.

The basic data, postoperative complications and postoperative reexamination of 15 patients with severe internal carotid artery stenosis treated by carotid intimal plaque stripping in the Neurosurgery Department of The First People’s Hospital of Changde City from January 2018 to September 2021 were analyzed retrospectively.

In one patient during pre-blocking, Doppler showed that the blood flow decreased by 50%, but the electrophysiology did not indicate abnormality, increased blood pressure and did not convert to blood flow. Electrophysiology and Doppler showed hypoperfusion in 3 patients, which improved after intraoperative conversion. All patients had no obvious complications after operation, and there was no restenosis after operation.

Carotid endarterectomy under multimodal monitoring is safe and effective in the treatment of severe internal carotid artery stenosis.
