Fig 1 Greater saphenous vein (GSV) diameter measured by ultrasound (US), computed tomography angiography (CTA)-lateral dimension, and CTA-antero-posterior (AP) dimension at the proximal thigh, mid-thigh, knee, mid-calf, and ankle. GSV diameter decreased from proximal thigh to the mid-calf and then increased to the ankle. GSV measurements by US and CTA were similar at all levels. P values represent comparisons of adjacent anatomic levels within each imaging modality.

Fig 2 Correlation between ultrasound (US) and computed tomography angiography (CTA) measurements of greater saphenous vein (GSV) at the level of the proximal thigh. Lateral measurements of the GSV by CTA are shown by black squares and antero-posterior (AP) measurements of the GSV are shown in white squares.

Fig 3 The usual course of the greater saphenous vein (GSV) with sample ultrasound (US) and computed tomography angiography (CTA) images shown at the proximal thigh, knee, and ankle. On the CTA images, the GSV is clearly visible and surrounding osseous landmarks are easily appreciated. CFV, Common femoral vein; SFJ, saphenofemoral junction.

Fig 5 Representative axial computed tomography angiography (CTA) images at the level just proximal to the ankle with (A) the typical noncontrast-enhanced greater saphenous vein (GSV) circled. (B) Arterial contrast bolus is starting to appear in the distal GSV (white circle).
