Angiodynography of the pelvic and deep leg veins was compared with ascending phlebography in a prospective study, comprising 102 examinations. Improved detection of flow following the introduction of the so-called "slow flow technique" permitted direct visualisation of the tibio-fibular veins in the second stage of this study (26 examinations). Demonstration or exclusion of femoro-popliteal thrombosis achieved a sensitivity of 95% and 90% respectively and a specificity of 99% and 97%. During the first part of this study, demonstration of calf vein thrombosis had a low sensitivity of 72%. This was improved by the introduction of a new high-pass filter resulting in the detection of all occlusions (nine). The sonographic signs of acute and chronic occlusions overlap somewhat. Colour demonstration showed eccentric, non-linear channels in two out of three cases and was able to exclude thrombus, although the veins could not be compressed.
在一项包含102例检查的前瞻性研究中，对盆腔和下肢深静脉血管造影与上行静脉造影进行了比较。在本研究的第二阶段（26例检查），采用所谓的“慢流技术”后，血流检测得到改善，使得胫腓静脉能够直接可视化。股腘静脉血栓形成的显示或排除分别达到了95%和90%的敏感性以及99%和97%的特异性。在本研究的第一部分，小腿静脉血栓形成的显示敏感性较低，为72%。通过引入一种新的高通滤波器，这一情况得到改善，能够检测到所有的闭塞情况（9例）。急性和慢性闭塞的超声征象有所重叠。彩色显示在三分之二的病例中显示出偏心、非线性通道，并且尽管静脉无法被压迫，但仍能够排除血栓。
