What are Iliac Veins?

The iliac veins are a pair of blood vessels that channel blood back to the heart. One of the iliac veins, called the internal iliac, drains blood from the body’s internal organs. The other, called the external iliac, receives blood from the legs. Both join together at the L5 level of the vertebra, forming the inferior cava.

Where are Iliac Veins Located? 

Iliac veins are a large structure that stretches from the abdomen down into the legs. The internal iliac vein drains the pelvic cavity, connecting to the lateral and median sacral veins, the vaginal and visceral veins, and the uterine veins.

The external iliac vein drains blood from the lower leg. It begins just inside the inguinal ligament and then passes up through the pelvis, where it joins other veins before proceeding to the inferior vena cava. 

What is May-Thurner Syndrome (MTS)?

May-Thurner Syndrome is a condition in which the right iliac article in the pelvis compresses the left iliac vein, decreasing the amount of blood returning from the left leg.

What Symptoms Are Associated with Iliac Vein Compression?

The restriction of blood flow can lead to a variety of symptoms that can affect your quality of life. Dr. Vargas and the Vascular Experts team often see patients with a range of symptoms, many of which can severely affect your quality of life. 

For instance, when pressure restricts blood flow, it can lead to swelling and pain, difficulties ambulating, which can affect mobility and feeling “heavy.” Blood can pool in the blood vessels, causing the walls to expand deep inside. And it can even raise the risk of deep vein thrombosis – something that can lead to heart complications. 

What Options are Available for Iliac Vein Compression Syndrome?

Here at The Vascular Experts, we offer a range of therapies designed to counter the symptoms of vein compression syndrome. 


A venography is a procedure that involves injecting you with contrasting material and then tracking the flow of blood using an X-ray device. 

Intravascular ultrasound

This technique is another imaging procedure that uses high-frequency sound waves to characterize the structure of your veins. We insert a small catheter into your blood vessels with an ultrasound probe attached to the end of it.

Venous stents 

A venous stent is a device that gently opens the blood vessels from the inside, permitting blood flow. 

Should I Consider an Iliac Vein Consultation?

If you’ve been experiencing any of the symptoms described above, including swelling and pain, you should consider scheduling a consultation with Dr. Vargas and the team. The first step is to use imaging techniques to determine whether there is a problem with the iliac vein. Then, if there is an issue with blood supply returning from the lower leg, we may recommend that you get a stent.
