NCT05196685 | Completed

• 1 other identifier: 10
• Study Type: observational
• Target: 195
• Locations: 1 country

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.

Conditions

Vertigo; Carotid Artery Diseases

Keywords

Vertigo; Imbalance; Doppler Ultrasonography; Carotid Artery; Vertebral Artery

Outcome Measures

Primary Outcomes (3)

• Carotid Stenosis

  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.

  1 year

• Resistive Index

  Measurements are taken from vertebral artery and formulated as below. Resistive Index = peak systolic velocity - end diastolic velocity\] / peak systolic velocity

  1 year

• Intima Media Thickness

  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.

  1 year

Study Arms (2)

Group Vertigo

Patients who have Carotid Doppler Ultrasonography and Vertigo screening test scores of 1 and above will be sent to ENT

Diagnostic Test: Carotid Doppler USG

Group control

Patients who have Carotid Doppler Ultrasonography and Vertigo screening test score below 1

Diagnostic Test: Carotid Doppler USG

Interventions

Carotid Doppler USG DIAGNOSTIC_TEST

All Doppler ultrasonography measurements will be made in a dimly lit room at room temperature, with the patient in the supine position, the head slightly hyperextended, the patient looking to the left when measuring the right side, and the patient looking to the right when measuring the left side. In all patients, common carotid artery (CCA), internal carotid artery (ICA) and vertebral artery (VA) gray scale and color Doppler ultrasonography wşll be performed using the GE 9L Linear Probe. Color Doppler examination will be performed with a frequency of 4.0/8.0 MHz.

Group Vertigo; Group control
