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

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

All patients who have a vascular problem and doppler USG.

Exclusion criteria

Patients with impaired cooperation, history of malignancy, presence of central nervous system pathology, presence of neurological disease affecting balance in the history, patients whose use of glasses may cause problems (epilepsy, vision loss, etc.) were excluded from the study.

Treatment and study plan

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.

Primary outcomes

Carotid Stenosis

Time frame: 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

Time frame: 1 year

Measurements are taken from vertebral artery and formulated as below.

Resistive Index = peak systolic velocity - end diastolic velocity] / peak systolic velocity
Intima Media Thickness

Time frame: 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.
