Extension of saphenous thrombus into the femoral vein: A potential complication of new endovenous ablation techniques

A, One week after treatment, thrombus (arrowhead) appears to protrude from the great saphenous vein (GSV) into the common femoral vein (CFV). B, Three months later, the thrombus is no longer visible.

A, Axial scan of the inguinal region showing the common femoral vein (CFV) and common femoral artery (CFA). In the left picture, the vein is partially filled by echogenic material (arrowhead). In the right picture, maximum compression with the probe was not able to produce vein collapse. B, One week later, as shown in the left picture, there was no filling defect in the vein, which collapsed (arrowhead in the right picture) as the probe compressed the inguinal region.

A, Longitudinal scan of the saphenofemoral junction showing the presence of thrombus in the common femoral vein (CFV) (arrows). B, Two weeks later, there was no color-filling defect in the CFV. The great saphenous vein (GSV) appears to be regularly occluded up to the superficial epigastric vein.
