The author reports data obtained by endoluminal pre and post-therapeutical ultrasound imaging of the wall architecture and lumen morphology of the arteries and varicose veins. In these studies, 20 and 25 MHz probes were used. These probes were covered with a 1 to 1.6 mm diameter flexible catheter and were introduced into the lumen of the vessels. Then, the probe was mechanically oriented in order to give, in cross-sectional section and real time, 360 degrees 2D images. The anatomical elements of the vessel wall and lumen, visualized with this technique, were described. The intima and adventitia appeared as echogenic structures while the media appeared as a non echogenic structure. The characteristics of endoluminal reactions such as atheromatous plaque, stenosis, thrombogenic and sclerogenic reactions were described. In conclusion, endovascular ultrasound imaging shows, accurate images of the morphology and dynamics of the arterial and venous vessel lumen and wall. This new technology can be used helpfully before, during and after vessel medical or surgical treatment.
作者报告了通过腔内治疗前后对动脉和静脉曲张的壁结构及管腔形态进行超声成像所获得的数据。在这些研究中，使用了20兆赫和25兆赫的探头。这些探头覆盖有直径为1至1.6毫米的柔性导管，并被引入血管腔内。然后，对探头进行机械定位，以便在横截面和实时状态下获得360度的二维图像。描述了用该技术可视化的血管壁和管腔的解剖结构。内膜和外膜表现为回声结构，而中膜表现为无回声结构。描述了诸如动脉粥样斑块、狭窄、血栓形成和硬化反应等腔内反应的特征。总之，血管内超声成像显示了动脉和静脉血管腔及壁的形态和动态的精确图像。这项新技术可在血管医学或外科治疗前、治疗中和治疗后发挥有益作用。
