Value of Ultrasound Combined with CTA in the Diagnosis of Extracranial Carotid Plaque in Patients with Cerebral Infarction

Objective To investigate the value of ultrasound combined with computed tomography angiography(CTA) in the diagnosis of extracranial carotid plaque in patients with cerebral infarction.Methods 98 patients with cerebral infarction with carotid plaque admitted to our hospital from August 2016 to August 2018 were selected,and received the ultrasound and CTA examinations within one week of onset.At the same time,40 patients were randomly selected for digital subtraction angiography(DSA).The detection rates of carotid artery stenosis,plaque and plaque location by ultrasound,CTA and DSA were compared.Results A total of 588 vessels were examined in 98 patients undergoing ultrasound and CTA examination,while 240 vessels were examined in 40 patients undergoing DSA examination.The detection rate of carotid artery stenosis by CTA and DSA was higher than that by ultrasound(P<0.05).Ultrasound and CTA were less consistent in the diagnosis of mild and moderate carotid stenosis and more consistent in the diagnosis of severe and complete occlusion carotid stenosis.Among the 98 patients,135 plaques were detected by ultrasound,149 by CTA,and 88 plaques were detected by DSA in 40 patients.The detection rate of internal carotid artery plaque by CTA was significantly higher than that by ultrasonic examination(P<0.05).Ultrasound and CTA were consistent in detecting soft plaque,flat plaque,hard plaque and ulcerative mixed plaque.Ultrasound and CTA were also consistent in the detection of plaques at the bifurcation of common carotid artery and common carotid artery.Conclusion Compared with the results of DSA,ultrasound and CTA have advantages in the diagnosis of extracranial carotid plaque,location and degree of carotid stenosis in patients with cerebral infarction.The results of the two methods are consistent,moreover,the combined detection has higher diagnostic value than the single detection and is worthy of clinical application.
