What is May-Thurner Syndrome?

May-Thurner Syndrome, commonly referred to as Iliac Vein disease, is a condition that increases one’s chances of developing a blood clot. Since blood clots can be life-threatening, people with this condition need to be careful to alleviate the formation of blood clots.

In most cases, blood clots are characterized by tenderness or pain around the area with the clot and swelling that appears reddish or purple in color.

Is May-Thurner Syndrome Hereditary?

Is May-Thurner Syndrome genetic or inherited? No, May-Thurner Syndrome is not a hereditary disease. Actually, it’s a condition that usually comes about when the right iliac artery compresses the left iliac vein. This also means that people with May-Thurner Syndrome are more likely to suffer from Deep Vein Thrombosis also known as DVT, in their left leg. DVT is more common in the left lower extremity versus the right. May-Thurner Syndrome is considered to be a risk factor for people who already have left-sided DVT. Although research varies on how many people in the U.S. are affected by May-Thurner Syndrome, close to 900,000 people have DVT and around 60,000-100,000 die from complications related to DVT or pulmonary embolism.

May-Thurner Syndrome is considered to be a rare complication of DVT; however, DVT is quite common and very preventable. It is uncommon for people to realize they have May-Thurner Syndrome unless you have already been diagnosed or have seen symptoms of DVT. There are few warning signs; however, swelling is one of the most common, visible signs you may have May-Thurner Syndrome.

Causes of May-Thurner Syndrome

While it’s normal for blood vessels to cross each other, the position of the iliac vessels may cause the iliac artery to press the left iliac vein against the spine.

This means blood circulation around this region will be restricted. When this is the case, the increased pressure may lead to scaring in the vein, or blood clots in more extreme situations.

While this condition is random, there are factors that may aggravate it. These include the following:

  • Oral birth control
  • Scoliosis
  • Pregnancy and childbirth
  • Multiple pregnancies or births
  • Dehydration
  • Any condition that causes blood to clot
  • Take medications that cause blood to clot more frequently

May-Thurner Syndrome is also more prevalent in women, even though there are men who suffer from this condition as well.
