目的:探讨超微血流成像技术（SMI）在评价大动脉炎（TA）患者颈动脉新生血管的价值以及经验总结。方法:应用SMI分析于中国医科大学附属盛京医院确诊的23例TA患者，共计38条颈总动脉，检测增厚的血管管壁厚度，增厚的管壁中新生血管情况，并与超声造影（CEUS）结果相对比，比较两者诊断的一致性。结果:SMI可以清晰地显示TA患者颈动脉管壁增厚情况，并且可以显示极细小的血流通道。总计有34条血管经SMI可检测到新生血流信号，评分为1分的23条，SMI检查可见星点状低速血流，评分为2分的11条，SMI检查可见弥漫点状或条状低速血流。与之对应的，总计有34条血管经CEUS可检测到新生血流信号，22条血管CEUS评分为1分，12条血管CEUS评分为2分。30条血管SMI结果与CEUS结果相一致，两组间评分结果一致性良好（Kappa=0.663，P<0.01）。结论:SMI可作为TA患者增厚的颈动脉管壁新生血管的重要筛查手段之一。在TA患者诊断、治疗、随访中具有潜在的应用价值。“,”Objective:To investigate the value of superb micro-vascular imaging (SMI) in evaluating carotid neovascularization in patients with Takayasu arteritis (TA).Methods:SMI was used to analyze the wall thickness and neovascularization in a total of 38 common carotid arteries in 23 patients with TA diagnosed in Shengjing Hospital of China Medical University, and the results were compared with contrast-enhanced ultrasound (CEUS).Results:SMI could clearly show the thickening wall of the common carotid artery in TA patients, and could show very tiny blood flow channels in the thickening wall. Neovascularization was detected in a total of 34 common carotid arteries by SMI, 23 of which showed 1 point of score with scattered low-velocity blood flow and the rest of which showed 2 points of score with diffused spots or strips with low-velocity blood flow. Correspondingly, neovascularization was detected in a total of 34 common carotid artery by CEUS, 22 of which showed 1 point of score and the rest of which showed 2 points of score. The scores of the two groups were consistent (n Kappa=0.641, n P<0.01).n Conclusions:SMI can be used as one of the important screening methods for neovascularization assessment in thickened carotid wall in patients with TA, which shows potential application value in the diagnosis, treatment and follow-up for TA patients.
