We confirmed the diagnostic capacity of vascular ultrasonography (VU) in deep vein thrombosis (DVT) of the legs and studied the role of VU in the diagnostic process. The subjects were 42 legs with swelling of the legs in 31 patients who underwent VU and ascending venography (VG) of the legs. In VU, the positive criter-ia were (1) the presence of intravenous echoes,(2) no crushing of the veins by compression with the probe, and (3) disappearance of flow rate changes due to respira-tion and manual pressure on the legs. The rate of correct diagnosis was studied. The clinical features before the examination were scored, and the subjects were divided into three groups (group H with a high possibility of DVT, group M with a moderate possibility, and group L with a low possibility).

The following results were obtained: 1) DVT was diagnosed by VG in 22 legs. The specificity of VU was 95% (19/20) and the sensitivity was 95% (21/22).

2) The percentage of DVT patients in the clinical feature classification before the examination was 92% in group H, 58% in group M and 22% in group L.

It was concluded that VU was useful in the diagnosis of DVT, and by combining VU with the clinical feature evaluation method. non-invasive and accurate diagnosis and rapid treatment should be possible.
