When most people think of veins, the first thing that comes to mind is the superficial veins in the arms and legs. However, there are other veins in the body, including the iliac veins. In this blog post, we will discuss everything you need to know about iliac veins!
What are Iliac veins?
The iliac veins are two large veins that drain blood from the lower limbs and pelvis. They are located on either side of the body and are part of the venous system. The internal iliac veins are connected to the femoral veins, which are located in the thigh. Blood from the lower limbs and pelvis is returned to the heart through the iliac veins.
The iliac veins are important for blood circulation in the lower limbs and pelvis. If they become blocked or damaged, it can lead to serious health problems. The internal iliac veins can be affected by a number of conditions, including deep vein thrombosis (DVT), pelvic vein thrombosis, and iliac vein compression syndrome. Treatment for these conditions may involve medication, surgery, or other interventions.
Anatomy of the Common Iliac Vein
Blog Introduction: The common iliac vein is an important structure in human anatomy. It is one of two major veins that carry deoxygenated blood from the lower body to the heart. Knowing the anatomy of this vein, its location, and its function can be helpful for doctors, medical students, and other healthcare professionals who are involved in diagnosis and treatment. Let’s take a closer look at what exactly the internal iliac vein is.
What Is The Common Iliac Vein?
The common iliac vein is one of two major veins that carries deoxygenated blood from the lower body to the heart. It runs along each side of your spine and begins at the level of L5 (the fifth lumbar vertebrae) on either side. It then moves up through your internal pelvis until it reaches its end point at the right atrium of your heart. The other major vein that carries deoxygenated blood from your lower body to your heart is called the inferior vena cava. Together, these two veins form a large loop called the venous arch which helps return blood from your legs and abdomen back to your heart.
Three Main Branches of the Iliac Vein
The internal iliac vein has three main branches: an internal branch, an external branch, and a middle branch. These branches help carry deoxygenated blood from several different organs in your abdomen region including your liver, gallbladder, pancreas, small intestine, colon, spleen, and kidneys back to your heart for re-circulation throughout your body. This process helps ensure that oxygen-rich blood gets circulated throughout all parts of your body so you can stay healthy and active!
In addition to these three main branches, there are also several smaller tributary veins that connect with the common iliac vein as well as a series of valves that help regulate flow within this vein system. These valves play an important role in ensuring proper circulation throughout your body by preventing backflow within this system which could lead to stagnation or pooling of blood if left unchecked.
The internal iliac veins and external iliac veins are essential structures in our bodies responsible for carrying deoxygenated blood from our lower body organs back up to our hearts for re-circulation throughout our bodies.
Left Common Iliac Vein
The left common iliac vein is one of two large veins that run through the pelvis, draining blood from the lower body. It is important to understand what this vein is and how it works in order to maintain good overall health.
Location of the Left Common Iliac Vein
The left common iliac vein is located in the abdomen and is part of the larger venous system which carries deoxygenated blood back to the heart from all parts of the body. The left common iliac vein begins at the external iliac vein, which drains blood from the lower left leg, and terminates at the inferior vena cava, which delivers deoxygenated blood to the right side of the heart. The right common iliac vein starts at a similar point but on the other side of your body. On its way up through your pelvis, it also connects with other veins and organs including your bladder, uterus (if you are female), prostate gland (if you are male), rectum, sigmoid colon, and appendix.
Function of the Left Common Iliac Vein
The primary function of any vein is to direct deoxygenated blood back to your heart so that it can be re-oxygenated before it circulates back around your body. This process helps deliver oxygen to your organs so they can function properly. Carrying oxygenated blood is the main function of veins.
Carry Oxygenated Blood
In addition, veins play an important role in regulating your body temperature as they carry heat away from your extremities into more central areas where it can be dissipated or released through sweat production or respiration.
Finally, because veins often act as pathways for fluid drainage, they help ensure that excess fluid does not build up in certain areas of your body like your legs or feet.
The left common iliac vein plays an important role in keeping our bodies healthy by helping regulate temperature, fluid levels, and oxygen circulation throughout our bodies. It’s essential for adults to understand this important part of their anatomy so they can stay educated about their health and make sure they’re taking proper care of their bodies. With proper knowledge and care, we can all keep our bodies functioning optimally.
Where are iliac veins located?
The iliac veins are a pair of large veins that drain blood from the lower limbs and pelvis. They are located on each side of the body, just below the waist. The iliac veins are the largest veins in the body and are essential for proper blood circulation.

Venous Outflow
The iliac veins are vital for proper blood circulation and play a crucial role in the circulatory system. Without them, blood would not be able to return to the heart properly and would eventually pooled in the legs and pelvis, causing serious health problems.
What are the functions of iliac veins?
The iliac veins are a pair of large veins that originate in the pelvis. They carry blood from the lower extremities and abdominal organs back to the heart. The right iliac vein drains into the inferior vena cava, while the left iliac vein drains into the left renal vein.
The iliac veins are important for the return of blood to the heart. They help to maintain blood pressure and prevent pooling of blood in the lower extremities. Additionally, they help to regulate blood flow to the kidneys and other organs in the abdomen.
What are the common diseases and conditions associated with iliac veins?
The iliac veins are a pair of large veins that drain blood from the lower limbs and pelvic organs. They are located on either side of the pelvis and converge to form the common iliac veins, which then drain into the vena cava. The iliac veins are subject to a number of diseases and conditions, some of which are listed below.
Diseases and conditions associated with the iliac veins include:
Iliac Vein Compression Syndrome
Iliac Vein Compression Syndrome or May-Thurner syndrome: This is a condition in which the left iliac vein is compressed by the overlying right iliac artery. This can lead to blockages or blood clots in the vein, which can in turn cause pain, swelling, and other symptoms in the legs. May-Thurner syndrome may be common in middle aged women.
Symptoms of May Thurner Syndrome
The most common symptom associated with Iliac Vein Compression Syndrome is chronic leg pain or swelling on one side. Other symptoms include difficulty walking, leg cramps after sitting for long periods of time, discoloration around ankles or veins in legs, and a feeling of heaviness in the affected leg. If you experience any of these symptoms for more than two weeks it’s important to see your doctor right away so they can diagnose you correctly. Your doctor may order imaging tests such as an MRI or CT scan to help diagnose this condition.
Treatment for May Thurner Syndrome
If you are diagnosed with Iliac Vein Compression Syndrome it’s important to seek treatment right away to reduce your risk of further complications. Treatment options may include medications such as anti-inflammatory drugs or blood thinners to reduce inflammation and improve circulation; lifestyle changes such as avoiding prolonged sitting; physical therapy; compression stockings; and surgery if necessary to alleviate pressure on the affected area. It’s important to note that not all treatments will work for everyone so it is best to discuss with your doctor what type of treatment will be most effective for you before starting any new regimen.
Pelvic Congestion Syndrome
Pelvic congestion syndrome (PCS): This is a condition that affects women and is characterized by chronic pain in the pelvis, thighs, and low back. It is thought to be caused by dilated or varicose veins in the pelvis, including the iliac veins.
Causes of Pelvic Congestion Syndrome
The exact cause of PCS is unknown; however, there are some theories as to why it occurs. One theory suggests that PCS may be caused by hormonal imbalances or alterations in blood flow due to pregnancy or childbirth. Another theory suggests that PCS could be caused by blockages in the ovarian or pelvic veins—usually due to a blood clot—that limit normal blood flow from the lower abdomen back up to the heart. It’s also possible that genetics may play a role in developing PCS.
Treatment for Pelvic Congestion Syndrome
Treating PCS requires a combination of lifestyle changes and medical treatments. Lifestyle changes such as exercising regularly, eating a balanced diet, avoiding tight clothing around the waist or groin area, maintaining good posture when standing for long periods of time, and elevating your legs when sitting for extended periods of time can all help reduce symptoms of PCS. Medical treatments such as medications for reducing inflammation or relieving pain may be prescribed if needed; however, surgery is often recommended for severe cases of PCS if lifestyle changes are not effective. Surgery involves removing or blocking off parts of the vein where blood has backed up and pooled over time so that normal blood flow can resume to reduce symptoms of PCS.
Deep Vein Thrombosis
Deep vein thrombosis: This is a condition in which blood clots form in the deep veins of the body, including the iliac veins. Deep vein thrombosis can cause pain, swelling, and other symptoms in the affected limb, and can lead to serious complications if the clot breaks free and travels to the lungs (pulmonary embolism).
Symptoms of Deep Vein Thrombosis
The signs and symptoms of DVT include swelling in one or both legs; pain or tenderness in the affected area; redness or warmth over the affected area; skin discoloration in affected areas; increased skin temperature over affected areas; and cramping or heaviness in affected areas. These symptoms may not be present for all individuals with DVT but if you experience any combination of these symptoms seek medical attention immediately.
Treatment for Deep Vein Thrombosis
If you are experiencing any of these symptoms your doctor will likely order an ultrasound to diagnose whether or not you have DVT. Depending on the severity of your condition they may also order other tests such as blood tests or CT scans. Treatment for DVT typically includes anticoagulants (blood thinners), compression stockings to reduce swelling and improve circulation, physical therapy to maintain mobility and reduce pain, and sometimes surgical interventions such as thrombolysis (the injection of medication into a clotted vein) or thrombectomy (the removal of clots).
If you are experiencing any symptoms that may be associated with diseases or conditions of the iliac veins, it is important to see your doctor for an evaluation.
How can iliac vein conditions be treated?
The iliac veins are the large veins that drain blood from the pelvis and lower limbs. They are subject to a number of conditions that can cause problems with blood flow. Treatment for iliac vein conditions depends on the specific condition, but may include medications, surgery, or other interventions.
Iliac vein thrombosis is a condition in which a blood clot forms in the iliac veins. This can block blood flow and cause pain and swelling in the affected leg. Treatment for iliac vein thrombosis may include anticoagulant medications, thrombolytic therapy, or surgery.
Iliac vein stenosis is a condition in which the iliac veins become narrowed, restricting blood flow. This can cause pain and swelling in the affected leg. Treatment for iliac vein stenosis may include angioplasty or surgery.
Varicose veins are another condition that can affect the iliac veins. In this condition, the veins become enlarged and twisted, which can cause pain and swelling. Treatment for varicose veins may include lifestyle changes, such as avoiding standing or sitting for long periods of time, wearing compression stockings, or having surgery to remove the affected veins.
Iliac veins are large veins that drain blood from the pelvis and lower limbs. They are located on either side of the body, in the area known as the iliac fossa. Iliac veins have a number of important functions, including carrying blood back to the heart and helping to regulate blood pressure.
There are a number of diseases and conditions that can affect the iliac veins, such as venous insufficiency, deep vein thrombosis (DVT), and pelvic congestion syndrome. Treatment for these conditions typically involves lifestyle changes, medications, or surgery.
The iliac veins play a vital role in the circulatory system and should be given due care and attention to maintain good health.
