Thrombosis of the internal jugular vein and the subclavian vein is often caused by central venous catheters. Doppler blood flow imaging (duplex sonography and color flow imaging) is very useful to establish the diagnosis, as soon as signs of venous obstruction occur after placing a catheter. Twenty-six patients with clinically suspected thrombosis were examined; in 25 patients thrombosis of the internal jugular or subclavian vein was diagnosed. By means of duplex sonography and color flow imaging, the degree of venous obstruction can easily be determined. The efficiency of therapy can be controlled. With color flow imaging, blood flow direction and velocity can be visualized in color which provides global information about hemodynamics in a short time. Furthermore, color flow imaging is a suitable method to detect even small subcutaneous collaterals.
颈内静脉和锁骨下静脉血栓形成常由中心静脉导管引起。一旦在放置导管后出现静脉阻塞迹象，多普勒血流成像（双功超声和彩色血流成像）对于确立诊断非常有用。对26例临床怀疑有血栓形成的患者进行了检查；其中25例诊断为颈内静脉或锁骨下静脉血栓形成。通过双功超声和彩色血流成像，可以很容易地确定静脉阻塞的程度。可以控制治疗效果。通过彩色血流成像，血流方向和速度可以用颜色显示，从而在短时间内提供有关血流动力学的整体信息。此外，彩色血流成像也是检测即使是很小的皮下侧支循环的合适方法。
