Iliac Vein Compression Syndrome

May-Thurner Syndrome

Intravascular Ultrasound

Intravascular Ultrasound (IVUS) is a cutting edge, catheter based, ultrasound technology, which allows for precise identification of iliac vein obstructions as well as guidance for intravascular stent placement. The IVUS catheter is about the size of a tip of an ink pen, the end of which has a tiny ultrasound element which allows imaging of the vein from within.

IVUS enables us to directly examine the pelvic veins (iliac veins) which are responsible for draining the blood from the legs back to the heart. Obstruction of the iliac veins from external compression by the overlying iliac artery and the posteriorly located lumbar spine leads to high pressure in the veins below that point. Signs and symptoms of this increased pressure may include pelvic, buttock or hip pain which are typically worse after prolonged sitting or standing. Pelvic congestion syndrome occurs due to the development of cross pelvic collateral “varicose” veins, which may cause increased pelvic pain with menstruation, during or after intercourse(dyspareunia) or when lifting weight or bearing down as in squatting. Iliac vein compression may also contribute to recurrent venous complaints after previous vein ablation or previous vein stripping or excisions. Unexplained unilateral lower extremity edema, thickened & discolored lower leg skin and non-healing leg ulcers may also be caused by significant compression or obstruction of the iliac veins. Advancements in iliac vein ultrasound testing, as well as the application of ultrasound from within the actual vessel (IVUS), has enabled us to more accurately identify pelvic vein occlusive disease. Prior to IVUS there was not an accurate enough test to document iliac vein compression syndrome (IVCS) or post thrombotic (blood clot) iliac vein obstruction. Under IVUS direction, we can now identify disease previously not considered or recognized and offer appropriate patients definitive therapy with iliac stent placement which, with IVUS, can be sized accurately and confirmed to be fully expanded.

IVUS Guided Stent Placement

Iliac vein stent placement is most accurately and precisely accomplished with the use of IVUS. Based on the results of the diagnostic IVUS procedure, individualized plans of therapy can be established based on the location and severity of narrowing. IVUS directed stenting of the diseased (compressed or post thrombotic) segments may be performed either at the time of the diagnostic IVUS exam or in a staged fashion at a later date. IVUS is used to measure the severity of the narrowing (by calculating luminal area reduction compared to expected normal areas which yields a specific percentage of narrowing). Upon completion of stent placement and balloon expansion of the stent when needed, IVUS is also used to confirm optimal stent expansion and apposition of the stent to the vessel wall. Once the lumen of the vein is restored to normal (stented) flow through the stented vein may be increased up to 90% depending on the difference between pre and post stent lumen area . This is analogous to a traffic jam on the highway caused by multiple lane closures, which is then relieved immediately once the barriers have been removed 4 lanes of traffic have been restored. Although placing stents in arteries has been performed for 30 years or more, and IVUS has been used in clinical practice in the arteries and veins for the last 10 years, the application of these two technologies, in concert, to evaluate and treat iliac vein compression syndrome and pelvic vein congestion is the most recent and significant advance in the field of phlebology, or vein care. IVUS has changed our approach for treating patients with either first time or recurrent venous insufficiency whose lower extremity venous insufficiency ultrasounds may not match their clinical severity. It is this group of patients who are most likely to benefit from further iliac vein assessment with intravascular ultrasound to determine whether they might be candidates for iliac vein stent placement.

Iliac Vein Compression

Under IVUS direction, we can now treat disease previously not recognised or appreciated. Stents can be sized accurately and post deployment expansion can be confirmed with IVUS.

    Thank you Dr. Magnant for your amazing work. I had 3 types of vein treatments in both my legs this month. It's a fabulous feeling & seeing the results of having no more pain & swelling. My only regret is that I didn't find you 8 years ago when I started having problems. Best part of it, was your surgical table side manner. Thank you for making me laugh!

    I went to see Dr. Magnant for a varicose vein I didn’t like. Sometimes I had restless legs & swelling. Being in my 30’s I never thought that what I thought was a superficial problem could have lead to more serious problems later in life and other problems I was having already were all related to my veins. Dr. Magnant makes you feel so comfortable and is really good at distracting you while doing the procedure that’s it feels so quick and painless. I have already recommended ppl go see him because why should anyone wait till the problem is severe. If you have thought about it go see him he’s the best:))

    I experienced pelvic pain for over a year. Multiple doctors, MRI, CT Scans, Xrays, Physical Therapy, Pain Management Injections.....with NO relief. All tried to treat the pain & no one could tell me what was causing the pain. Then I found Vein Specialists........after my initial appointment not only did they diagnose the pain (May Thurner Syndrome) but they had a plan of action to eliminate it. I had many questions & concerns.......all were addressed and I proceeded with the IVUS treatment. I was awake (by choice) during the procedure. Not only was I fascinated with the technology, but I got to witness first hand how amazing Dr. Magnant & his staff were!! I had a post-op concern & Dr. Magnant himself called me on a weekend to address it. I also had issues with my insurance/prescription companies and his wonderful staff solved those (annoying!) issues. THANK YOU! THANK YOU! My new "normal" is PAIN FREE!!!! I highly recommend Vein Specialists!!!!!!

    Couldn't be happier I chose Dr. Magnant for my procedure. Both Dr. and staff put you at ease before, during and after the surgery. He specializes and only performs vascular surgery, which is the reason I chose Vein Specialists. Anyone considering varicose vein treatment should seek treatment by Dr. Joseph Magnant!

    I sought help primarily for leg pain at the front of my shins. Testing indicated valve leakage in veins in both legs and a bilateral procedure was recommended. A few hours after the right vein procedure was performed I had total relief from the pain. There was minimal discomfort during and afterward. Dr. Magnant and his staff are very knowledgeable and caring. Everything was explained thoroughly from the initial examination, through the procedures, and after the post procedure ultra sounds. Unquestionably the doctor to see for vein problems.

    I just had my follow-up ultrasound done on my left leg today. I had the right leg done on Monday of last week. Glad to report no clots in either leg. Clotting is the complication they seemed most concerned about.
    If any of my friends are dealing with the pain and discomfort of varicose veins or just tired of the ugly appearance of bulging veins in your legs. I can highly recommend Dr Magnant and his extremely professional staff.
    I have had visible veins in my right leg since a knee injury when I was a teenager. Over the years it had grown to affect both legs. Likely from always being on my feet for work, and especially because I often had employment that involved a lot of crouching/squatting down. Sometimes until my lower legs fell asleep. I fortunately have always been an active person outside of work and regular exercise kept the pain at bay for many years. But I'm no spring chicken anymore.
    A little over two years ago, my assignment changed at work and I now spend more time at my desk . Within a few months the pain at the end of the day really began bothering me (and I have a very high pain tolerance).
    This was the third specialist I had been to locally in the last two years. I don't want to name the others, however I will say that they all seemed to be rather disorganized for a medical facility, or the staff seemed to be overwhelmed and the diagnostic procedures (ultrasound particularly) done before the actual surgery were not even comparable to the level of care I received from every member of the staff here.
    I am also very fortunate and blessed to have excellent insurance that covered the procedure 100% since my deductible was already met for the year.
