摘要
目的评价彩色多普勒超声及多层螺旋CT对颈动脉狭窄介入术后疗效,为预测颈动脉狭窄介入术预后情况提供参考。方法 20例高血压性颈动脉狭窄患者介入治疗前后应用彩色多普勒超声仪测量相关血流动力学参数,并运用多层螺旋CT监测术前术后颈动脉狭窄处内径、狭窄长度等变化,并随访患者术后血压情况。结果经介入治疗后,颈内动脉AT下降、AC增加明显,PSV流速明显减低,治疗前后差异有统计学意义(P<0.05)。CT诊断中发现50条颈动脉的狭窄率为80.0%。术后随访6个月,患者收缩压和舒张压明显下降(P<0.05)。结论通过彩色多普勒超声可准确测量颈动脉狭窄处血流动力学的变化,并对介入颈动脉狭窄术后疗效做出比较客观和准确的诊断,多层螺旋CT可准确判断颈动脉狭窄的程度、长度以及血管内表面,两种检查均为无创、可重复应用,可准确评价高血压合并颈动脉狭窄患者介入术后的疗效。
Objective To provide the reference for predicting the prognosis, using color doppler ultrasound and spiral CT to assess carotid artery stenosis after interventional therapy. Methods 20 patients with hypertensive ca- rotid stenosis used the ultrasound to detect the related hemodynamic parameters before and after intervention, and used spiral CT to monitor the change of the carotid artery stenosis in length, diameter, etc. And the postoperative blood pressure was followed-up. Results After intervention, the carotid AT decreased, AC increased obviously, and a signif- icant decrease in PSV velocity, with significant difference before and after treatment （P〈0.05）. the stenosis rate of CT diagnosis was 80.0% in 50 carotid artery. Followed up for 6 months, the systolic blood pressure decreased significant- ly （P〈0.05）, diastolic blood pressure increased significantly （P〈0.05）. Conclusion The color doppler ultrasound can accurately measure the carotid stenosis＇ hemodynamic change, and make a objective and accurate diagnosis for the ca-rotid artery stenosis＇ effect after interventional therapeutic. Spiral CT can accurately judge the extent, length and blood vessels inside surface,of the carotid artery stenosis. The two inspections are all non-invasive, can repeat application and accurately evaluate the curative effect for the high blood pressure with carotid artery stenosis after interventional therapy.
