PART 4 — PERIPHERAL VENOUS
Figure 14-3 A transverse view of the bifurcation of the com- mon femoral artery into the superficial femoral artery (SFA) and deep (profunda) femoral artery (PFA) while the great saphenous vein (GSV) terminates into the common femoral vein (CFV).
In the upper thigh, the CFV is formed by the junc- tion of the femoral vein (FV) (formerly known as the superficial femoral vein) and the deep femoral vein (DFV) (also known as the profunda femoris vein) (Fig. 14-5).
Femoral Vein and Deep Femoral Vein
The FV will be more superficial than the DFV (Fig. 14-6). They will parallel each other through most of the thigh. The FV is the main venous outflow of the calf, whereas the DFV mainly drains the thigh itself. The entire length of the FV should be exam- ined in detail (Figs. 14-7 and 14-8) with compression

images often documented in the upper thigh, mid- thigh, and distal thigh. The DFV should be examined as well. Most protocols include a compression of the DFV near its terminus into the CFV. The remainder of the DFV may be too deep and may have many tributaries such that complete examination of its en- tire length may be difficult.
The FV through the thigh may be a bifid system (Fig. 14-9). This is fairly common and simply means that the examiner must be sure to investigate each vessel. In the case of a patient with a bifid system and a venous thrombosis, it is not uncommon for one FV to be patent while the other is thrombosed.
