目的研究颈部动脉超声诊断短暂性脑缺血(TIA)发作的临床效果。方法选取睢县人民医院TIA患者64例为TIA组,另选同期55例健康体检者为正常组,颈动脉超声检查两组颈动脉狭窄情况及斑块情况,分析颈部动脉超声诊断价值。结果 TIA组轻度狭窄、中度狭窄、重度狭窄发生率分别为50.0%、28.1%、12.5%,与对照组比较差异有统计学意义(P<0.05),正常组无狭窄率显著高于TIA组(P<0.05);TIA组64例患者共48例检出斑块,检出率为75.0%,正常组4例(7.3%)检出斑块,差异有统计学意义(P<0.05),正常组硬斑发生率较高,但与TIA组比较差异未见统计学意义(P>0.05),TIA组斑块类型以软斑为主,与正常组比较显著升高(P<0.05);TIA组Vs平均值为(33.61±10.25)cm/s、脑血流量为(712.36±101.58)ml/min,与正常组的(42.36±13.25)cm/s、(1025.18±135.94)ml/min比较显著降低(P<0.05)。结论颈部动脉超声可反映TIA患者与正常者颈动脉差异,对大脑血流动力学检测有较高准确性,具有较高的临床应用价值。
Objective To study the clinical effect of ultrasonic diagnosis of transient ischemic attack (TIA) of the neck artery. Methods Sixty-four TIA patients in Tiaoxian People’s Hospital were selected as TIA group. 55 normal healthy subjects were selected as the normal control group. The carotid artery stenosis and plaque were examined by carotid artery ultrasonography. The diagnostic value of cervical artery was analyzed. Results The incidences of mild, moderate and severe stenosis in TIA group were 50.0%, 28.1% and 12.5%, respectively, which were significantly different from those in control group (P <0.05). The stenosis rate in normal group was significantly higher than that in TIA group (P <0.05). In 64 TIA patients, 48 cases were detected, the detection rate was 75.0%, and in the normal group 4 cases (7.3%), the difference was statistically significant (P <0.05) (P> 0.05). The plaque type in TIA group was predominantly soft spot, which was significantly higher than that in normal group (P <0.05), but the difference was not statistically significant (33.61 ± 10.25) cm / s in TIA group and (712.36 ± 101.58) ml / min in cerebral infarction group were significantly higher than those in normal group (42.36 ± 13.25 cm / s, 1025.18 ± 135.94) ml / min (P <0.05). Conclusion The diagnosis of carotid artery can reflect the difference of carotid artery in TIA patients and normal persons, and has high accuracy in hemodynamic test of brain and has high clinical value.
