缺血性脑卒中患者的超微血流显像颈动脉斑块特征分析

Analysis of Carotid Plaque Characteristics on Superb Micro-vascular Imaging in Patients with Ischemic Stroke

分析超微血流显像(SMI)颈动脉斑块特征与缺血性脑卒中发生率的关系。选取96例颈动脉斑块患者作为研究对象,随访期间有76例发生缺血性脑卒中,将其作为研究组,其余未发生缺血性脑卒中的20例患者作为对照组。两组均行SMI检查,获得颈动脉斑块特征。与对照组相比,研究组患者斑块厚度、斑块长度、斑块钙化程度、脂质程度水平较高,纤维化程度水平较低(P<0.05)。随斑块厚度、斑块长度、斑块钙化程度、脂质程度的增加,以及纤维化程度的降低,缺血性脑卒中发生率增加,斑块厚度>4 mm、斑块长度>20 mm、斑块钙化程度>20%、脂质程度>20%、纤维化程度<50%的颈动脉斑块患者缺血性脑卒中发生率最高。SMI对缺血性脑卒中的诊断准确率为97.37%(P>0.05)。SMI颈动脉斑块特征与缺血性脑卒中发生率联系密切,且SMI对缺血性脑卒中的诊断价值较高。

This paper analyzed the relationship between superb micro-vascular imaging(SMI) carotid artery plaque characteristics and the incidence of ischemic stroke. Selected 96 patients with carotid artery plaque as research subjects, there were 76 patients occurred ischemic stroke during follow-up and set as the study group, and the remaining 20 patients without ischemic stroke were the control group. Both the two groups underwent SMI to obtain carotid plaque characteristics. Compared with the control group, the plaque thickness, plaque length, calcification degree, lipid degree were higher and the level of fiber degree were lower in the study group(P<0.05). With the increase of plaque thickness, plaque length, plaque calcification degree, lipid degree, and the decrease of fiber degree, the patients’ incidence of ischemic stroke increased, and those with plaque thickness> 4 mm, plaque length>20mm,plaque calcification degree>20%,lipid degree>20%,and fiber degree<50% had the highest incidence of ischemic stroke.The diagnostic accuracy of SMI for ischemic stroke was 97.37%(P>0.05).In conclusion,the plaque characteristics of SMI are closely related to the incidence of ischemic stroke,and the SMI has a high value in the diagnosis of ischemic stroke.
