Measuring Optic Nerve Sheath Diameter to Predict Neurological Issues in Carotid Surgery

Can Ultrasonographic Screening of Optic Sheath Diameter Be an Early Detector of Norological Morbidities Related Carotis Endarterectomy

Observational Başakşehir Çam & Sakura City Hospital · NCT06491693

This study is testing if measuring the optic nerve sheath diameter during carotid surgery can help predict neurological problems in older patients with narrowed carotid arteries.

What this trial studies

This observational study aims to evaluate how changes in the Optic Nerve Sheath Diameter (ONSD) during Carotid Endarterectomy (CEA) can help predict neurological complications in patients post-surgery. It focuses on elderly patients with carotid artery stenosis, who are at risk for ischemic strokes. By monitoring ONSD alongside other standard perioperative parameters, the study seeks to improve early detection of cerebral hypoperfusion and ischemia during the surgical procedure. The findings could enhance patient safety and outcomes by identifying those at higher risk for neurological morbidities.

Who should consider this trial

Good fit: Ideal candidates are male and female patients aged 50 to 80 scheduled for elective carotid endarterectomy under general anesthesia.

Not a fit: Patients under 50 years of age, over 80 years of age, or those with neurological issues unrelated to carotid lesions will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring and prevention of neurological complications in patients undergoing carotid endarterectomy.

How similar studies have performed: While the approach of using ONSD measurements is gaining attention, this specific application in the context of carotid endarterectomy is relatively novel and has not been extensively tested in prior studies.
