摘要
目的比较超声与数字减影血管造影(DSA)诊断颈动脉粥样硬化性狭窄的差异。方法对340例缺血性脑血管病患者行颈动脉超声及全脑DSA检查,其中短暂性脑缺血发作(TIA)患者105例,脑梗死患者235例;又根据年龄分为青年组(n=54)、中年组(n=137)和老年组(n=149)。结果超声与DSA检查均发现梗死组颈动脉狭窄高于TIA组(P<0.05);超声与DSA检查均发现老年组颈动脉狭窄高于中年组和青年组(P<0.05),中年组高于青年组(P<0.05);超声检查颈动脉颅外段动脉狭窄与DSA相比,狭窄、闭塞及总体符合率分别为89.39%、80.85%、87.15%。结论颈部血管超声联合应用DSA对颈动脉粥样硬化的病因、诊断、临床治疗及术前评估与术后随访意义重大。
Objective To compare the difference of ultrasound and digital subtraction anginography （DSA） in diagnosing carotid atheriosclerosis. Methods A total of 340 patients of ischemic cerebrovascular disease with carotid atheriosclerosis were examined with ultrasound and DSA. They were divided into cerebral infarction group （n=235） and transient ischemic attack （TIA, n=105）, and also were divided into the young-aged group （n= 54）, middle-aged group （n=137） and oldaged group （n= 149） by age. Results Both of the ultrasound and DSA found that the incidence of carotid artery stenosis in cerebral infarction was higher than that in TIA （P〈0.05） ; the incidence that of carotid artery stenosis in old-aged group were higher than that in middle-aged and young-aged group （P〈0.05）, and in middle-aged group was higher than that in young-aged group. Taking DSA as standard, the accordance rate of ultrasound in diagnosing stenosis, clot and both of them were 89.39%, 80. 85%, 87.15%, respectively. Conclusion Carotid artery ultrasound has high sensitivity in diagnosis of carotid atheriosclerosis. Either carotid artery ultrasound or DSA has advantages. With combination of two methods, there will be an important significance in the diagnosis, clinical treatment, assess before operation and follow-up after operation in patients with carotid atheriosclerosis.
