Which veins are commonly duplicated?
The FV is most commonly duplicated, with the mFV being the most frequently duplicated segment. In addition, 15.3% of the studies had a duplicated segment missed on a previous or subsequent examination.
Is the popliteal vein important?
The popliteal vein is one of the major blood vessels in the lower body. It runs up the back of the knee and carries blood from the lower leg to the heart. Sometimes, a blood clot, or a thrombosis, can block this important vein. This is known as a deep vein thrombosis (DVT).
What does the popliteal vein do?
The popliteal vein is a deep vein of the leg. It drains blood away from the leg into the femoral vein, which drains blood to the inferior vena cava to return to the right atrium of the heart.
Is popliteal vein a deep vein?
Your popliteal vein is one of the blood vessels that carries blood from your legs back to your heart. It runs behind your knee and up the back of your thigh. It’s one of the vessels doctors call a “deep vein” because it’s far underneath your skin.
Can you have two popliteal veins?
Background: Duplication of the popliteal and superficial femoral veins (PV, SFV) is a normal variant previously reported in up to 25% of limbs. Little clinical significance, however, has been attributed to this apparently common anomaly.
Is popliteal a vein or artery?
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.
Is pain behind knee a blood clot?
The popliteal vein runs behind the knee and transports blood back up to the heart. When a blood clot forms in this vein, doctors refer to it as popliteal vein thrombosis. Symptoms include pain, swelling, and redness in the leg and knee area.
How many popliteal veins are there?
Blood flows into the popliteal vein from multiple tributaries in the lower leg, including the:3. The popliteal vein itself originates where the anterior and posterior tibial veins join together, at the back of the knee. From there, the popliteal vein runs through the popliteal fossa.
How long does a venous duplex ultrasound take?
You will hear the sound of moving blood during the exam. Do not be alarmed; it is harmless. Your exam will take approximately 15 to 30 minutes.
How is a venous duplex performed?
During a lower extremity venous duplex scan, the veins in the legs and ankles are viewed. A special jelly is placed on the area being examined while a wand like device called a transducer is passed lightly over the skin over the vein.
What does popliteal vein drain into?
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….

What happens when the popliteal artery is damaged?
Long-term pressure on the popliteal artery can cause the artery to narrow (stenosis), causing pain and cramping with just slight activity, such as walking. In severe cases or when undiagnosed, the nerves and muscles in the leg can become damaged. Blood clots may occur in the lower leg (deep vein thrombosis).
What causes popliteal vein thrombosis?
When a blood clot forms in this vein, doctors refer to it as popliteal vein thrombosis. Symptoms include pain, swelling, and redness in the leg and knee area. Popliteal vein thrombosis can occur due to poor blood flow, damage to a blood vessel, or an external injury.
How long is the recovery time after popliteal bypass surgery?
It is normal to feel tired for several weeks after your operation. This will gradually improve; most people take about 6 weeks to recover fully.
Where is popliteal vein located?
The popliteal vein is found within the popliteal fossa. The popliteal fossa is defined by the biceps femoris proximolaterally; the semimembranosus and semitendinosus muscles proximomedially; and gastrocnemius distally. The tibial nerve, popliteal vein, and popliteal artery are all found within the fossa.
What three things are the Examiner trying to assess when performing a venous duplex examination?
The three main goals in diagnosing venous thrombosis are to determine the following:
- The presence or absence of thrombus.
- The relative risk for the thrombus dislodging and traveling to the lungs.
- The competence of the venous valves.
How common is duplication of the popliteal and superficial femoral veins?
Background: Duplication of the popliteal and superficial femoral veins (PV, SFV) is a normal variant previously reported in up to 25% of limbs. Little clinical significance, however, has been attributed to this apparently common anomaly.
Where is the popliteal vein located?
The popliteal vein is located posterior to the knee in the popliteal region that is a major route for venous return from the lower leg. The vein forms from the combination of the anterior and posterior tibial vein at the border of the popliteal artery.
What is incomplete vein duplication?
Incomplete duplication is seen as the popliteal vein splits into two (15.6%) or three (3.1%) tributaries as it travels through the popliteal fossa. 2 A study of CT venography found one side is typically dominant (has a higher blood flow) in cases of duplication or splitting. 5
What happens if you have a blood clot in your popliteal vein?
The popliteal vein is one of the most common locations for a deep vein thrombosis (DVT), or blood clot within a vein, to occur. This is very dangerous as there is a risk of the blood clot breaking free and traveling to the heart or lungs and causing a pulmonary embolism (PE).
