[摘要] 目的 探究TCD联合颈部血管超声检查在诊断脑梗死患者中的应用价值。方法 方便选择2014年9月—2015年9月之间，在该院临床上确诊为脑梗死患者60例，应用TCD联合CUS检测，分别与单纯的TCD、CUS相比较，观察统计其检查疾病的灵敏度。 结果 结果可看出TCD联合CUS检测和单纯的TCD，结果差异有统计学意义（χ2=10.909，P=0.002）；和单纯的CUS检测比较，两种方法检测结果差异有统计学意义（χ2=15.420，P=0.000）。结论 TCD联合颈部血管超声检查针对患者的血管壁及血流动力学的变化差异有统计学意义，并且两种检测方法和单纯的一种检查方法相比准确率较高，且具有无创性、方便快捷等优点，也有利提高疾病的诊断率，值得在临床推广。

[Abstract] Objective To discuss the application value of TCD combined with carotid doplex ultrasound examination in diagnosis of patients with cerebral infarction. Methods 60 cases of patients with cerebral infarction diagnosed in our hospital in clinic from September， 2014 to September， 2015 were selected and detected by TCD combined with CUS， and the sensitivity of it in examining diseases was observed and counted compared with that of simple TCD and simple CUS. Results The difference in the detection result between TCD combined with CUS and simple TCD was obvious with statistical significance （χ2=10.909，P=0.002）， the difference in the detection result between TCD combined with CUS and simple CUS was obvious with statistical significance（χ2=15.420，P=0.000）. Conclusion There were obvious differences in changes of blood vessel wall and hemodynamics of patients by TCD combined with carotid doplex ultrasound examination， the accuracy rate of combined detection method is higher than that of simple detection method with the advantages of non-invasion and convenience and quickness， and it also conducive to improving the diagnosis rate of diseases and is worth clinical application.

脑梗死（CI）主要分为缺血性卒中和出血性卒中，而缺血性卒中包括腔隙性梗死、脑血栓形成以及脑栓塞等。有关资料显示[1]，缺血性卒中约占全部脑卒中的70%以上，主要由于脑血液供应障碍导致的。脑梗死主要由于脑组织局部供血不足或者急剧减少，导致该血管的供血不足，引起缺氧致使正常脑组织的软化和坏死。常伴有相应部位的临床症状，如失语、偏瘫等神经功能缺失的症状[2]。一般临床上以DSA为首选的检测手段，但是DSA对患者具有一定的创伤性，有一定几率会给患者造成神经系统的并发症等，而TCD和颈部血管超声检查检测脑梗死患者具有无创性、价格便宜且可重复性高的等诸多优点，同时能够准确的检查出颅内外血管的各种病变，效果显著，便于高效率的治疗。……
