Endovascular Iliocaval Reconstruction Helping Restore Iliac Veins
Share this

Healthy veins are critical to returning blood from the body to the heart. However, in some cases, scar tissue from blood clots can form in the veins, causing them to narrow or become blocked. This can lead to significant swelling in the legs which may cause wounds. People often develop scar tissue in the veins due to:

  • Anatomic compression
  • Blood clots
  • Prior catheters in veins
  • Radiation therapy for cancer
  • Surgery on adjacent organs or body parts

The iliac veins, which are responsible for draining your legs, are susceptible to a buildup of scar tissue from blood clots. Iliac veins then merge with veins draining the pelvis to form one large vein called the inferior vena cava, which is responsible for carrying blood from the lower body and kidneys to the heart.

Endovascular iliocaval reconstruction allows us to repair the veins draining our legs and the inferior vena cava damaged by scar tissue. As a result, people can regain healthy blood flow from their legs to their heart and reduce the risk recurrent swelling or wound formation.

How Endovascular Iliocaval Reconstruction Works

To understand how endovascular iliocaval reconstruction may work, think of veins with scar tissue as four-lane highways after a snowstorm. If a snowplow plowed a single lane of the highway and only opened a path a small car could drive through, you could imagine the traffic that would result! Now if you think of that narrow path as a blood vessel, it’s too small for blood to flow through—which causes a buildup in pressure. By using stents, or metal tubes, that we insert into the veins from minimally invasive puncture sites behind the knee or in the groin, we push the remaining scar tissue to the side, making sure that you get all four lanes of blood vessel flowing again and alleviating any pressure that has built up in the legs.

We’ve found that about 87 percent of the veins we open up with a stent remain open after five years—a significantly higher number than surgeons achieved using older techniques, such as open bypass surgery.

How Does This Technique Compare to Traditional Ones?

Older techniques used to reconnect veins typically bypassed (went around) the blocked or narrowed veins. These surgeries were invasive, requiring a large incision that spread from the bottom of the chest to below the belly button. During surgery, surgeons would make an incision in both groins, take plastic tubing or a donated vein, and use it to make a detour around the blocked area.

The problem with this surgery is that it leads to many more complications than newer minimally invasive techniques and people experienced recurrent blood clots or scarring in the same veins years after surgery. Compared to bypass surgeries, endovascular reconstructions allow patients to have:

  • Natural blood flow: Following bypass surgery, patients’ blood moves in a new bypass tunnel as opposed to a person’s own vein.
  • Shorter recoveries: Patients return home the same or next day with the new procedure, compared to five to seven days after a bypass surgery.
  • Additional surgeries: If scar tissue recurs after the bypass, many other surgical options aren’t possible after open surgery. Endovascular iliocaval reconstruction usually doesn’t limit future treatment options if a vein becomes narrowed again.
