彩色多普勒超声在脑梗死患者颈动脉检查中的应用(1)
摘要：目的 分析探讨彩色多普勒超声在脑梗死患者颈动脉检查中的应用价值。方法 选取2013年1月～2016年7月我院收治的60例脑梗死患者作为观察组，再选取同时期非脑血管患者100例作为对照组。分析比较两组患者的彩色多普勒超声颈动脉检查影像学结果。结果 观察组患者的斑块检出率大于对照组，差异有统计学意义(P<0.05)；比较斑块发生部位，两组患者的左侧斑块与右侧斑块比较均无统计学意义(P>0.05)；斑块多分布于颈总动脉分叉处(BIF)，差异有统计学意义(P<0.05)；两组患者的斑块特征比较无统计学意义(P>0.05)；比较两组患者的管腔狭窄检出率，差异有统计学意义(P<0.05)。结论 彩色多普勒超声能准确判断颈动脉斑块的发生部位和类型，对脑梗死的发生和诊断有重要的临床应用价值。

Abstract：Objective To explore the application value of color Doppler ultrasound in carotid artery in patients with cerebral infarction in the examination. Methods 60 cases of cerebral infarction were selected from January 2013 ～2016 year in July in our hospital as the observation group，and selected the same period of non cerebrovascular patients 100 cases as control group.The analysis of color Doppler ultrasound of carotid artery imaging were compared between the two groups results. Results In the observation group，the plaque detection rate than the control group，the difference was statistically significant(P<0.05)；comparison of plaque area，two groups of patients with left and right plaques were plaque no statistical significance (P>0.05)；plaque distribution in carotid artery bifurcation(BIF)，the difference was statistically significant (P<0.05)；plaque characteristics of the two groups were not statistically significant(P>0.05)； compared two groups of patients with luminal stenosis rate，the difference was statistically significant (P< 0.05). Conclusion Color Doppler ultrasound can accurately determine the location and type of carotid plaque，and has important clinical value in the diagnosis and treatment of cerebral infarction.

脑梗死指局部脑组织由于多种原因出现区域血液供应障碍，导致脑组织缺血缺氧性病变坏死[1]。尤其是随着人们生活水平的提高和人口老龄化的加剧，我国脑梗死的发病率逐年提高。而动脉粥样硬化是脑梗死的重要病因，对了解脑梗死动脉硬化和病变程度有重要参考价值[2]。我院采用彩色多普勒超声对患者的颈动脉进行检测，分析探讨动脉硬化斑块和脑梗死的關系以及彩色多普勒超声临床诊断脑梗死的价值，现报道如下。
1 资料与方法
1.1一般资料 选取2013年1月～2016年7月期间我院收治的60例脑梗死患者作为观察组，再选取同时期的非脑血管患者100例作为对照组。观察组中男36例，女24例，年龄38～79岁，平均年龄(63.14±6.67)岁；对照组中男58例，女42例，年龄35～80岁，平均年龄(62.07±8.46)岁。比较两组患者的一般资料无统计学意义(P>0.05)，有可比性。

1.2方法
1.2.1诊断方法 仪器采用我院自有的西门子G50彩色多普勒超声诊断仪，设置线阵探头频率为7.5～10 MHz，凸阵探头频率为3.5 MHz。患者取仰卧位，头向后仰，偏向检测对侧倾斜，充分暴露颈部。检查人员常规探查患者的颈总动脉(CCA)、BIF、颈内动脉(ICA)和颈外动脉(ECA)。探查过程中确保超声纵轴与血管方向平行，声束与血流夹角<60°。探查主要内容包括血管内径、颈动脉中层内膜厚度、有无斑块、斑块部位、大小、数目、回声特征以及管腔有无狭窄。
1.2.2斑块分型 若患者同一血管内有多处斑块，以最严重的部位为主。①扁平斑：血管内膜粗糙，厚度增加，局部轻微隆起；②软斑块：斑块突出，回声不均，表面光滑且连续；③硬斑块：斑块高低不平，回声强，部分伴声影；④溃疡斑：斑块面积较大，基地较宽，表面有凹面，边缘回声低。, http://www.100md.com(吴颖)
