Figure 3a. Coronal venogram of the thigh in three patients illustrates anomalies of the SFV. (a) Short segment lateral duplication (arrow) of the SFV. (b) Long segment lateral duplication (arrow) of the SFV. (c) Complex venous anatomy of the SFV demonstrates three vessels at the midthigh level. Arrows indicate duplicated vessels.
