The common femoral artery and vein (arteria & vena femoralis communis) proximally to the branching points of the deep femoral artery and vein, respectively.
The subsartorial artery and vein (arteria & vena subsartorialis) distally to these branching points. In the past, this segment has been called the superficial femoral artery and vein. This was a potentially harmful misnomer since it is clinically a deep vein and not a superficial vein, and thus a possible site for a deep vein thrombosis, that may be overlooked as a superficial vein for anticoagulant therapy.[1] In 2001, during the World Congress of the International Union of Phlebology, it was decided to change the name from superficial femoral vein simply to femoral vein,[2] but the use of superficial femoral vein still persists in some sources. Therefore, the term subsartorial vein was introduced as a replacement name for the distal segment.[3][4]
