Real time mode B echotomography completes ultrasound exploration of supra-aortic trunks. Continuous Doppler recording is essential for detection of vessels and identification of significant lesions. However, it cannot detect arterial wall lesions that have no effect on arterial blood flow but can be at the origin of migrating emboli. The latter can be visualized by echotomography, which localizes the lesion and allows evaluation of its morphologic and anatomic characteristics. The methodology of the examination and normal anatomic findings are summarized and the different types of lesion occurring in the supra-aortic trunks described. The limitations of echotomography are discussed and a description given of a semiology of vascular ultrasonic structures of emboligenic potential.
实时B型超声断层扫描可完成主动脉弓上血管的超声探查。连续多普勒记录对于血管检测和显著病变的识别至关重要。然而，它无法检测对动脉血流无影响但可能是游走栓子起源的动脉壁病变。后者可通过超声断层扫描显示，该技术可定位病变并评估其形态学和解剖学特征。总结了检查方法和正常解剖学发现，并描述了主动脉弓上血管出现的不同类型病变。讨论了超声断层扫描的局限性，并对具有潜在栓子形成能力的血管超声结构的症状学进行了描述。
