腔内凸阵超声探头检测颈动脉的初步研究

目的 探讨腔内凸阵超声探头体外途径检查颈动脉的应用价值.方法 选取43例患者86支颈动脉作为研究对象,用高频线阵探头、低频凸阵探头及腔内凸阵探头分别检测颈总动脉(CCA)内径、收缩期峰值流速(PSV),颈内动脉(ICA)内径、PSV、异常血管形态及显示长度等参数并进行比较.结果 3种不同频率超声探头所测ICA内径、PSV、显示长度比较具有显著性差异;ICA异常形态血管比较,腔内探头与高频探头之间有统计学差异.结论 腔内凸阵探头检测ICA具有较高的临床应用价值.

Abstract：

Objective To assess the value of an intracavitary convex array probe in detecting internal carotid artery (ICA) disease. Methods Eighty-six carotid arteries in 43 cases were examined with intracavitary convex array probe, low-frequency convex array probe and high-frequency linear probe to collect the data including the ICA visible length, peak systolic velocity (PSV), internal diameter, blood vessel shape; common carotid artery (CCA) intimae-medial thickness (IMT), PSV, and internal diameter. Results Significant differences were noted in the visible length, PSV of ICA, and internal diameter detected by different frequency ultrasound probes. Intracavitary probe and high-frequency probe produced significantly different findings of the blood vessel shape. Conclusion Intracavitary convex array probe has important clinical value in detecting of ICA disease.
