Aortosternal Venous Compression: A Review of Two Cases

Figure 2

(a) Proximal segment of the left IJV demonstrates patency. (b) Diffuse slow flow of the compressible left IJV with the near stagnant flow in the proximal left IJV. (c) Comparison between the right IJV (A) and left IJV (B), with the left IJV demonstrating increased echogenicity of the blood suggesting underlying aggregation with near stagnant to and fro flow of blood. This layered appearance could be seen in the setting of underlying proximal compression/obstruction. Right IJV (A) was observed to be patent with the nonsluggish flow.
