As in the upper limbs, most deep veins of the lower limbs have
the same names as the arteries they accompany and many are
double. Poorly supported by surrounding tissues, the two su-
perficial saphenous veins (great and small) are common sites of
varicosities. Te great saphenous (
saphenous

obvious) vein is
frequently excised and used as a coronary bypass vessel.
Description and Areas Drained
Deep veins.
AFer being formed by the union of the
medial
and
lateral plantar veins
, the
posterior tibial vein
ascends
deep in the calf muscle and receives the
fibular (peroneal) vein
(Figure 19.30)
. Te
anterior tibial vein
, which is the superior
continuation of the
dorsalis pedis vein
of the foot, unites at
the knee with the posterior tibial vein to form the
popliteal
vein
, which crosses the back of the knee. As the popliteal vein
emerges from the knee, it becomes the
femoral vein
, which
drains the deep structures of the thigh. Te femoral vein be-
comes the
external iliac vein
as it enters the pelvis. In the pel-
vis, the external iliac vein unites with the
internal iliac vein
to
form the
common iliac vein
. Te distribution of the internal
iliac veins parallels that of the internal iliac arteries.
Superficial veins.
±he
great
and
small saphenous veins
(sah-fe
9
nus) issue from the
dorsal venous arch
of the foot (²ig-
ure 19.30b and c). Tese veins anastomose frequently with each
other and with the deep veins along their course. ±he great
saphenous vein is the longest vein in the body. It travels superi-
orly along the medial aspect of the leg to the thigh, where it emp-
ties into the femoral vein just distal to the inguinal ligament. Te
small saphenous vein runs along the lateral aspect of the foot and
then through the deep fascia of the calf muscles, which it drains.
At the knee, it empties into the popliteal vein.
