多模态超声检查预测TIA患者短期脑卒中风险的价值

Multimode ultrasound inspection predicting short-term stroke risk in TIA

目的 分析颈动脉血管超声联合经颅彩色多普勒超声检查对短暂性脑缺血发作(TIA)患者短期脑卒中风险的预测价值。方法 选取2019-12—2021-12三亚中心医院确诊的34例短暂性脑缺血发作患者为研究对象,对所有患者均行颈动脉血管超声和经颅彩色多普勒超声联合检查,评估患者短期内脑卒中的发生风险。结果 所有患者检测部位均可见不同程度的血管狭窄,且血流信号异常,其中血管狭窄<50%共21例(61.76%),血管狭窄≥50%共13例(38.24%)。血管狭窄≥50%组中,2 d、7 d内卒中风险分别为30.77%、46.15%,血管狭窄≥50%组TIA患者短期卒中风险显著高于血管狭窄<50%组(P<0.05)。低危组中患者2 d、7 d内卒中风险分别为4.35%、4.35%,中、高危组中患者2 d、7 d内卒中风险分别为36.36%、45.45%,中、高危组TIA患者短期卒中风险显著高于低危组(P<0.05)。结论 颈动脉血管超声和经颅彩色多普勒超声联合用于短暂性脑缺血发作患者,能够观察血管狭窄和血流变化情况,同时对预测患者短期脑卒中风险也具有较好的效果。

Objective To analyze the predictive value of carotid vascular ultrasound and transcranial color Doppler ultrasound examination in short-term stroke risk in transient ischemic attack.Methods Thirty-four patients with transient ischemic attack diagnosed in Sanya Central Hospital from December 2019 to December2021 were selected as the study subjects,and all patients have a carotid vascular ultrasound and transcranial color Doppler ultrasound to assess the risk of stroke in the short term.Results Various degrees of vascular stenosis were seen in the detected sites in all patients,and blood flow signals were abnormal.Among these,21 cases had a vascular stenosis of 50%(61.24%),13 cases had a vascular stenosis of ≥50%(38.24%).In vascular stenosis 50% groups,the risk of stroke within 2d and 7d were 4.76% and 9.52%,respectively.In vascular stenosis ≥ 50%group,the risk of stroke within 2d and 7d were 30.77% and 46.15%,respectively.Vascular stenosis ≥50% group TIA patients have significantly higher risk in short-term strokes higher than vascular stenosis 50% group(P<0.05).In the low-risk group,the risk of stroke within 2d and 7d were 4.35% and 4.35%,respectively.In the middle and high risk group,the risk of stroke within 2d and 7d were 36.36% and 45.45%,respectively.In middle and high risk groups,the short-term stroke risk in TIA patients was significantly higher than that in the low-risk group(P<0.05).Conclusion Carotid vascular ultrasound and transcranial color Doppler ultrasound jointly used in patients with transient ischemic attack,can observe the patient's vascular stenosis and blood flow change,and it also has a good effect on predicting the short-term stroke risk in patients.
