1. Superficial
2. Deep
3. Perforators
1. Superficial
- There are divided into two parts
. 2. Small Saphenous vein
a). Great saphenous vein
.
Origin - it begins from medial side of. dorsal venous arch on the dorsum of the foot.
Course - after passing anterior to the. middle malleolus, it runs up . the medial side of the leg .
At the knee,it runs over the . posterior border of the medial . epicondyle the femur bone.
b). Small saphenous vein
.
Origin - it begins from lateral end of . dorsal venous arch at the dorsum of the foot .
Course - it courses around the lateral. aspect of the foot and runs along the posterior to the. lateral mellelous.
2.). Deep - there divided into the following-
. a) . Femoral vein
b) .Popliteal vein
c) . Peroneal vein
. a) Femoral vein-it begins at the adductor canal. It is a continuation of the Popliteal vein.it ends at the inferior margin of the inguinal ligament , where it becomes the external iliac vein.
Drainage-
. Popliteal vein
. .profunda(deep) femoris vein
. . Great saphenous vein
b) Peroneal Vein - The peroneal vein also known as fibular veins are deep veins that help carry blood from the lateral compartment of the leg .
They drain into the posterior tibial vein which will in turn drain into popliteal vein .
c) Popliteal vein- the Popliteal vein is located behind the knee. Its course runs along side the Popliteal artery but carries the blood from the knee joint and muscles in the thigh and calf back to the heart.
Origin- it is defined by the junction of the posterior tibial vein and . anterior tibial vein .
Drains- Peroneal vein reaching the knee. joint and turns into the femoral . veinwhen leaving the adductor canal
3) . Perforators - perforating veins connect the GSV to the deep vein of leg and thigh .
Presence of valves allow . blood from S.V to D.V.
