May-Thurner syndrome results from the right common iliac artery compressing the left common iliac vein. The iliac veins combine into the inferior vena cava to carry blood from the pelvis and lower limbs back to the heart. With the right common iliac artery crossing the left common vein north of the pelvis, the left iliac vein may be sometimes excessively compressed against the spine.

Such compression inherently compromises blood flow, causing blood to back up in the legs. In some cases, the compression may lead to clot formation, which also exacerbates circulation issues. From health issues (like swelling and pain) to aesthetic concerns (like damage to the skin,) such blockage in the blood vessels of the leg poses a serious hazard for one’s well-being.

Venous obstruction compromises blood flow from the lower legs back to the heart; thus, blood collects in the lower extremities with the pull of gravity. Some symptoms are swollen calves and ankles, heaviness, pain and ulcers. A person suffering from a blockage in one leg may also notice that this leg is larger than the other.

May-Thurner is a precursor for the above symptoms, but previous episode of blood clotting is also a common cause of venous obstruction. Because people with such venous disorders may not always show symptoms, noticeable swelling can be deemed evidence of severe deterioration of the vessels.. If treatment is in fact needed, a balloon is inserted into the compressed vein to dilate the vessel and a permanent stent is placed to keep the vein open. These procedure are routine and can be done safely in the office.

To avoid ulcers from forming or existing symptoms from deteriorating the vascular system further, see a venous expert as soon as possible.
