Endovascular Iliocaval Reconstruction

Blood clots, prior abdominal trauma, or abdominal surgeries can lead to scarring in the iliac veins. Dr. Steven Abramowitz discusses how endovascular iliocaval reconstruction can restore healthy blood flow.

Host: We’re speaking with Dr. Steven Abramowitz, a vascular surgeon at MedStar Washington Hospital Center. Thank you for joining us, Dr. Abramowitz.

Dr. Abramowitz: Thanks for having me.

Host: Today we’re discussing endovascular iliocaval reconstruction, a treatment for iliocaval thrombosis and other vascular conditions. Dr. Abramowitz, could you begin by discussing who the best candidates are for endovascular iliocaval reconstructions?

Dr. Abramowitz: Sure. It’s a mouthful. Endovascular iliocaval reconstruction is our way of rebuilding the connection in the veins, the structures that bring blood back to your heart. And, when the veins drain from your legs, they merge in your belly, like an upside-down Y and they form one big vein called the inferior vena cava. So, when we say iliocaval, we mean the iliac veins, which drain your legs, and the inferior vena cava, the main vein that they form inside the belly. What can happen is, in certain patients who have had blood clots in the past, or a history of trauma - maybe a gunshot wound to the belly, or even things like radiation therapy for cancer, or prior surgery - scar tissue can form around those veins. And those patients present with significant swelling in their legs and that swelling can also result in significant wound formation in both of the legs, as well. So, what we can do is, in a minimally invasive way, reconstruct the pathway, restoring flow from the legs back up to the heart to alleviate that jam of blood that’s increasing pressure in the veins.

Host: Can you explain how endovascular iliocaval reconstruction works?

Dr. Abramowitz: Absolutely. So, as I mentioned before, when these veins scar down, or block off and narrow, there’s usually a thin little bit left. And the best example I can give is your veins, normally, are like four-lane highways. But let’s say there’s a massive snowstorm and a snowplow has to get through. And it only puts a small path and it piles up all this snow on the sides of the road. Maybe only a bicyclist can get by, or a single car. And that narrowing, when you think about how blood has to flow, is just too little and so the blood builds up in pressure.  But what we can do is say we find that pathway, where that one snowplow went, and we can use a series of balloons and stents, which are metal tubes like tunnels, and we can expand and push that snow or scar tissue to the side, making sure that you get all four lanes flowing back again, and alleviating any pressure that’s built up in the legs.

Host: What is recovery normally like following this procedure?

Dr. Abramowitz: Recovery from this procedure is actually pretty easy. For the most part, we’re not making any incisions. So, this surgery is done through punctures, usually behind the knee or in the groin. So, people have some soreness at those puncture sites. The biggest complaint actually is back pain. We don’t really have nerves that tell us our veins are being stretched and so, after this procedure, the most common thing that people experience is a sense of muscle spasm that can last up to 2 to 3 weeks. And that’s really the stretch of that vein sitting in the body. So, you may not feel like you can get comfortable in your chair but you’re not going to feel like you’re in extreme pain.
