Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients undergoing carotid endarterectomy may suffer from neurologic deficits (ND) during the carotid cross-clamping due to cerebral hypoperfusion. An associated risk of postoperative stroke incidence is also well established.

The aim of this study is to evaluate the predictive factors associated with ND during CEA performed with RA. The perioperative implications of the ND were also evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients undergoing carotid endarterectomy may suffer from neurologic deficits (ND) during the carotid cross-clamping due to cerebral hypoperfusion. An associated risk of postoperative stroke incidence is also well established.

The aim of this study is to evaluate the predictive factors associated with ND during CEA performed with RA. The perioperative implications of the ND were also evaluated.

All consecutive patients from a tertiary referral center who underwent CEA for carotid artery stenosis (CS) and consecutive patients who presented alterations in the neurologic examination after ICA clamping during CEA are selected. The control patients, submitted to the same procedure but with no neurologic alterations, are consecutively selected.
