Abstract:
Introduction. The study is elaborated to evaluate carotid arteries
using color Doppler ultrasound in the diagnosis of ischemic stroke.
It is one of the leading causes of death in the world and are a
common cause of handicap for adults.
Purpose. The aim of the study is to demonstrate the association
of carotid artery stenoses with most cases of ischemic stroke.
Material and methods. The study was performed on 40
patients, examined at the General Electric Vivid S6 ultrasound, with
a linear array transducer of 7 MHz.
Data obtained refer to: the appearance and characteristics of the
atheromatous plaque (hypoechoic, hyperechoic, calcified) (Image
no 1), the gradation of stenosis based on the maximum systolic
velocity of the internal carotid artery (PSV), the PSV ratios between
the internal carotid artery and the common carotid artery.
Results. The highest incidence of stroke was found in the male
population. Out of 40 patients, 28 are men and 12 women, in the
age group 59-70 years. The carotid bulb was the common site of
atheroma plaque for 35 of 40 patients.
Also, based on PSV of ACI, 20 patients had
significant stenoses (greater than 60%), 11 - stenoses less
than 60%, and 9 patients had occlusion of the internal carotid
artery. The PSV ACI / ACC ratio was also a useful informative
indicator, according to which the result higher than 3
indicates significant stenosis (> 60%).
CT brain findings showed normal findings in cases,
whereas MCA infarct ( 18 cases ) were the most common
pathological involvement.
Conclusions. This study highlights the importance of
Doppler sonography in patients with ischemic stroke
with the association of the percentage of extracranial
carotid artery stenosis.
Color Doppler examination is a safe, informative,
economical method that requires little time to confirm
the cause of cerebrovascular insufficiency in extracranial
carotid artery system with subsequent guidance of
treatment modalities.
