Abstract：Objective To discuss the clinical ef fectiveness of contrast-enhanced ultrasound imaging
in assessment of carotid artery plaque neovascularization and plaques in patients with cerebral
infarction. Methods Altogether 100 cases of patients who suffered from carotid atherosclerotic
plaques and had taken ultrasound examinations from September 2014 to July 2015 in the hospital
were selected and divided into Infarction Group (36 cases) and Non-Infarction Group (64
cases) according to whether cerebral infarction symptoms associated with the affected side of
carotid artery appeared. Two groups of patients underwent ultrasound contrast imaging so as to
analyze the relationship between test results and the symptoms of infarction in patients. Results
In Infarction Group, the soft plaque was most frequently seen, which was followed by mixed
plaques; while, in Non-Infarction Group, mixed plaques were the most and the calcified plaques
came secondly in the quantity. In Infarction Group, Type II plaques were the most; while in
contrast, Type I plagues was the most in Non-Infarction Group. The mean stenosis degree (63.7%)
of Infarction Group was significantly higher than that of Non-Infarction Group (29.6%) (P<0.05).
The rate of hemorrhage in Infarction Group was significantly higher than that of Non-Infarction
Group (P<0.05). The integrity of fibrous cap in Non-Infarction Group was significantly higher
than that of Infarction Group (P<0.05). The degree of calcification was not significantly different
between the two groups (P>0.05). Conclusion The application of contrast-enhanced ultrasound
imaging in assessment of carotid artery plaque neovascularization and plaques in patients with
cerebral infarction provided a reference for reasonable diagnosis of the disease.
