【摘要】：目的探讨微细血管成像技术(SMI)在多发性大动脉炎(TA)分期诊断的价值。方法选取在我院就诊的多发性大动脉炎患者20例,进行颈动脉的常规超声、SMI及超声造影(CEUS)检查,按照ITAS2010评分标准分为病变活动期组和非活动期组,比较SMI技术与CEUS技术检测颈总动脉增厚管壁内新生血管增强程度的一致性。结果 CEUS技术显示活动期组颈总动脉增厚的管壁可见较多造影剂微气泡灌注,非活动期组可见少量或无造影剂微气泡灌注;SMI技术显示活动期组增厚的颈总动脉管壁见弥漫分布的点状或多条线样血流信号,非活动期组仅见星点状血流信号或无血流信号。活动期组SMI与CEUS具有很好的一致性(P0.01);非活动期组SMI与CEUS一致性不佳(P0.05)。结论 SMI技术可作为观察增厚管壁新生血管情况的重要筛查手段,对大动脉炎的临床分期诊断及治疗具有重要的指导意义。
[Abstract]:Objective to investigate the value of microvascular imaging technique (Smi) in the staging diagnosis of Takayasu arteritis (TAA). Methods Twenty patients with Takayasu arteritis in our hospital were examined by conventional ultrasound SMI and contrast-enhanced ultrasonography (CEUs). According to the ITAS2010 score, the patients were divided into active stage group and inactive stage group. To compare the consistency of SMI and CEUS in detecting the degree of angiogenesis in the thickened wall of common carotid artery, CEUS technique showed that there were more contrast media microbubbles perfusion in the thickened wall of the common carotid artery in active group. In the inactive group, a few or no contrast medium microbubbles were infused with SMI technique to show diffuse point or multiple linear blood flow signals in the thickened common carotid artery wall of the active group. In inactive group, there was only stellate blood flow signal or no blood flow signal. There was good consistency between SMI and CEUS in active phase group, but there was not good consistency between SMI and CEUS in inactive phase group. Conclusion SMI technique can be used to observe the wall neovascularization of thickened tube. Important screening methods for the situation, It has important guiding significance for clinical stage diagnosis and treatment of arteritis.
