Using a multichannel pulsed Doppler ultrasound device, studies of flow kinetics and vessel wall motility at the beginning of the internal carotid artery (ICA) were carried out. Regarding the results of special computer analysis in 120 subjects with healthy vessels, a dilation of the proximal ICA and a decrease in mean flow velocity which was related to the age of the individual could be assessed. Depending on age and risk factors, wall dyskinetics and turbulences in the dorso-lateral part of the vessel could be detected and confirmed by the flow imaging method. In a second study of 100 subjects (between 15 and 50 years of age) without risk factors, an age-dependent dilatation of ICA could be diagnosed by high resolution Duplex system. In the same study an increased incidence of wall thickening and plaques formation in the dilated area of the ICA was observed. The study of 234 patients with different risk factors showed that hypertonics developed an extended dilatation of the ICA and that wall thickening and plaque formation occurred significantly more often than in other risk groups.
使用多通道脉冲多普勒超声设备，对颈内动脉（ICA）起始处的血流动力学和血管壁运动进行了研究。关于120名血管健康受试者的特殊计算机分析结果，可以评估ICA近端的扩张以及与个体年龄相关的平均流速降低情况。根据年龄和危险因素，通过血流成像方法可以检测并确认血管背外侧部分的壁运动障碍和湍流。在第二项针对100名无危险因素的受试者（年龄在15至50岁之间）的研究中，通过高分辨率双功系统可以诊断出ICA的年龄依赖性扩张。在同一研究中，观察到ICA扩张区域壁增厚和斑块形成的发生率增加。对234名具有不同危险因素的患者的研究表明，高血压患者的ICA扩张范围扩大，并且壁增厚和斑块形成的发生率明显高于其他危险因素组。
