Is Carotid-Vertebral Doppler Ultrasonography Necessary for Patients With Vertigo?

Completed

• Conditions: Vertigo; Carotid Artery Diseases
• Interventions: Diagnostic Test: Carotid Doppler USG

• Registration Number: NCT05196685
• Lead Sponsor: Pamukkale University

Brief Summary

This study will be carried out prospectively on patients who applied to the cardiovascular surgery polyclinic and the carotid-vertebral artery doppler ultrasound due to the vascular problem. All patients will fill "Balance Disorder Scan Survey" and "Vertigo-Dizziness Imbalance Questionnaire-SS". Patients who score 1 and more are directed to the ear nose throat polyclinic and detailed differential diagnosis. Those who score 0 will be in control group.

Detailed Description

Right and left carotid artery flow velocities, intima-media thicknesses (IMT), presence of plaque, vertebral artery flow velocities, and vertebral artery resistance indexes (RI) will be recorded in all patients. Risk factor analysis, Vertigo Symptom Scale (VSS) and Dizziness Handicap Inventory (DHI-S) questionnaires will be applied to the patients in the ENT outpatient clinic. The differential diagnosis of vertigo will be made by performing detailed balance examinations and advanced balance tests.

Arm && Interventions

Group	Intervention	Description
Group Vertigo	Carotid Doppler USG	Patients who have Carotid Doppler Ultrasonography and Vertigo screening test scores of 1 and above will be sent to ENT
Group control	Carotid Doppler USG	Patients who have Carotid Doppler Ultrasonography and Vertigo screening test score below 1

Primary Outcome Measures

Name	Time	Method
Intima Media Thickness	1 year	The intima-media thickness will be measured 1 cm proximal to the start of the carotid bulb dilatation on the CCA in the far wall. Using the cine-loop function, an optimal longitudinal freeze-frame image in the end-diastolic state is measured manually.
Carotid Stenosis	1 year	ECST for Carotid Stenosis measurement will be used. In the ECST the estimated normal lumen diameter at the site of the lesion, based on a visual impression of where the normal arterial wall is before development of the stenosis, is used.
Resistive Index	1 year	Measurements are taken from vertebral artery and formulated as below.; Resistive Index = peak systolic velocity - end diastolic velocity\] / peak systolic velocity
