Anatomical terminology

The popliteal vein is a vein of the lower limb. It is formed from the anterior tibial vein and the posterior tibial vein. It travels medial to the popliteal artery, and becomes the femoral vein. It drains blood from the leg. It can be assessed using medical ultrasound. It can be affected by popliteal vein entrapment.

Contents

Structure

The popliteal vein is formed by the junction of the venae comitantes of the anterior tibial vein and the posterior tibial vein at the lower border of the popliteus muscle. It travels on the medial side of the popliteal artery. [1] It is superficial to the popliteal artery. [2] As it ascends through the fossa, it crosses behind the popliteal artery so that it comes to lie on its lateral side. It passes through the adductor hiatus (the opening in the adductor magnus muscle) to become the femoral vein. [1] [3]

Tributaries

The tributaries of the popliteal vein include:

Variation

The popliteal vein may be doubled in up to 35% of people. [2]

Function

The popliteal vein drains blood from the leg. [2]

Clinical significance

The popliteal vein is readily palpated in the popliteal fossa adjacent to the adductor magnus muscle. [4]

The popliteal vein can be visualised using medical ultrasound, including Doppler ultrasonography. [2] It may be affected by a thrombus. [2]

Popliteal vein entrapment

The popliteal vein may become trapped. [5] This reduces the flow of blood out of the leg, causing oedema, pain, and venous ulcers. [5] Entrapment is usually caused by gastrocnemius muscle. [5] Venography (using an x-ray) or magnetic resonance imaging can investigate it. [5] Surgery can be used to remove tissue creating pressure. [5]

<span class="mw-page-title-main">Human leg</span> Lower extremity or limb of the human body (foot, lower leg, thigh and hip)

The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur, tibia, and adjacent fibula. The thigh is between the hip and knee, while the calf (rear) and shin (front) are between the knee and foot.

<span class="mw-page-title-main">Thigh</span> The part of the body between the pelvis and the knee; upper leg

In anatomy, the thigh is the area between the hip (pelvis) and the knee. Anatomically, it is part of the lower limb.

<span class="mw-page-title-main">Femoral artery</span> Large artery in the thigh

The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh.

<span class="mw-page-title-main">Great saphenous vein</span> Large, subcutaneous, superficial vein of the leg

The great saphenous vein (GSV) or long saphenous vein is a large, subcutaneous, superficial vein of the leg. It is the longest vein in the body, running along the length of the lower limb, returning blood from the foot, leg and thigh to the deep femoral vein at the femoral triangle.

<span class="mw-page-title-main">Popliteal artery</span> Continuation of the femoral artery that supplies the lower leg

The popliteal artery is a deeply placed continuation of the femoral artery opening in the distal portion of the adductor magnus muscle. It courses through the popliteal fossa and ends at the lower border of the popliteus muscle, where it branches into the anterior and posterior tibial arteries.

<span class="mw-page-title-main">Femoral vein</span> Large blood vessel in the leg

In the human body, the femoral vein is the vein that accompanies the femoral artery in the femoral sheath. It is a deep vein that begins at the adductor hiatus as the continuation of the popliteal vein. The great saphenous vein, and the deep femoral vein drain into the femoral vein in the femoral triangle when it becomes known as the common femoral vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. Its major tributaries are the deep femoral vein, and the great saphenous vein. The femoral vein contains valves.

The posterior tibial artery of the lower limb is an artery that carries blood to the posterior compartment of the leg and plantar surface of the foot. It branches from the popliteal artery via the tibial-fibular trunk.

The anterior tibial artery is an artery of the leg. It carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery.

<span class="mw-page-title-main">Tibial nerve</span> Branch of the sciatic nerve

The tibial nerve is a branch of the sciatic nerve. The tibial nerve passes through the popliteal fossa to pass below the arch of soleus.

<span class="mw-page-title-main">Adductor magnus muscle</span> Muscle in the thigh

The adductor magnus is a large triangular muscle, situated on the medial side of the thigh.

<span class="mw-page-title-main">Gracilis muscle</span> Most superficial muscle on the medial side of the thigh

The gracilis muscle is the most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below.

The semimembranosus muscle is the most medial of the three hamstring muscles in the thigh. It is so named because it has a flat tendon of origin. It lies posteromedially in the thigh, deep to the semitendinosus muscle. It extends the hip joint and flexes the knee joint.

<span class="mw-page-title-main">Popliteal fossa</span> Depression at back of knee joint

The popliteal fossa is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia. Like other flexion surfaces of large joints, it is an area where blood vessels and nerves pass relatively superficially, and with an increased number of lymph nodes.

<span class="mw-page-title-main">Adductor canal</span> Aponeurotic tunnel in the middle third of the thigh

The adductor canal is an aponeurotic tunnel in the middle third of the thigh giving passage to parts of the femoral artery, vein, and nerve. It extends from the apex of the femoral triangle to the adductor hiatus.

The saphenous nerve is the largest cutaneous branch of the femoral nerve. It is derived from the lumbar plexus (L3-L4). It is a strictly sensory nerve, and has no motor function. It commences in the proximal (upper) thigh and travels along the adductor canal. Upon exiting the adductor canal, the saphenous nerve terminates by splitting into two terminal branches: the sartorial nerve, and the infrapatellar nerve. The saphenous nerve is responsible for providing sensory innervation to the skin of the anteromedial leg.

<span class="mw-page-title-main">Popliteal lymph nodes</span>

The popliteal lymph nodes, small in size and some six or seven in number, are embedded in the fat contained in the popliteal fossa, sometimes referred to as the 'knee pit'. One lies immediately beneath the popliteal fascia, near the terminal part of the small saphenous vein, and drains the region from which this vein derives its tributaries, such as superficial regions of the posterolateral aspect of the leg and the plantar aspect of the foot.

<span class="mw-page-title-main">Adductor hiatus</span> Gap between the adductor magnus muscle and the femur

In human anatomy, the adductor hiatus also known as hiatus magnus is a hiatus (gap) between the adductor magnus muscle and the femur that allows the passage of the femoral vessels from the anterior thigh to the posterior thigh and then the popliteal fossa. It is the termination of the adductor canal and lies about 8–13.5 cm (3.1–5.3 in) superior to the adductor tubercle.

<span class="mw-page-title-main">Posterior compartment of thigh</span> One of the fascial compartments that contains the knee flexors and hip extensors

The posterior compartment of the thigh is one of the fascial compartments that contains the knee flexors and hip extensors known as the hamstring muscles, as well as vascular and nervous elements, particularly the sciatic nerve.
