本文介绍了一种新型的超声速度检测仪在周围血管疾病评价中的应用。该仪器采用了一个传感器，可以在外部使用，以定性评估动脉和静脉血流的速度。一束超声波穿过皮肤、皮下组织和血管。血液中的微粒元素使传输信号的频率偏移的量与它们的速度成正比。偏移的频率被放大并呈现为可听信号。由于该仪器适用于研究手臂和腿部所有水平的流速，因此可以估计闭塞的长度并评价闭塞远端血管的通畅性。对于静脉疾病，已发现流速检测器可用于定位手臂和腿部从外侧紫静脉到腘静脉的静脉阻塞。对髂股动脉血栓切除术的结果进行即时和长期评估也是可行的。还可以估计下腔静脉结扎前后的静脉血流动力学。
The application of a new ultrasonic velocity detector in the evaluation of peripheral vascular diseases is described. This instrument employs a transducer which may be used externally to assess qualitatively the velocity of arterial and venous flow. A bean of ultrasound is passed through the skin, subcutaneous tissue, and blood vessel. The particulate elements in blood shift the frequency of the transmitted signal by an amount directly proportional to their velocity. The shifted frequencies are amplified and presented as an audible signal. Since the instrument is applicable to the study of flow velocity at all levels of the arm and leg, it is possible to estimate the length of an occlusion and evaluate the patency of the vessels distal to the occlusion. With venous disease, the velocity detector has been found useful in localizing venous obstruction of the arm and In the leg from the level of the external lilac to the popliteal vein. Immediate and long-term assessment of the results of iliofemoral thrombectomy is also feasible. The dynamics of venous flow before and after ligation of the inferior vena cava may also be estimated.
