The main purpose of this study is to investigate the contribution of changes in Optic Nerve Sheath Diameter (OSNC) measured at different periods during Carotid Endarterectomy (CEA) operations to the prediction of neurological problems detected in the postoperative period. The secondary aim of the study is to examine the relationship between optic nerve sheath diameter measurement and other routinely used perioperative follow-up parameters in terms of predicting neurological problems.
Male and female patients between the ages of 50 and 80, who are planned for elective CEA under general anesthesia, who come in a spontaneously breathing, conscious and cooperative state.
Patients who are under 50 years of age, over 80 years of age, have neurological findings caused by reasons other than carotid lesion, and are intubated.
