What is Ultrasound Guided Injections (USGI)/Endovenous Chemical Ablation (EVCA)?
USGI/EVCA is the injection of a strong sclerosant (a liquid that kills the lining of the vein) into a deep vein using the Ultrasound device to guide the injected solution to its proper location. The purpose is to seal an incompetent vein to avoid a surgical procedure.
What is USGI/EVCA best recommended for?
It is best for the perforating veins and parts of the deep Greater Saphenous Vein once ligation has occurred. Lasers are sometimes used to shut down the perforators.
What are the benefits of a (USGI)/(EVCA)?
This procedure is only used in large, deeper veins not visible to the eye. The only other way to stop venous reflux is with surgery. Some of the current surgical procedures are cosmetically mutilating, causing greater morbidity and a greater expense; and in many cases, the percentage of positive outcomes is less than with USGI/EVCA.
Can this procedure (EVCA) be used on all large veins?
No. Studies have shown us that it is most effective on veins less than 6 mm.
Can it be used to seal the major junctions (Saphenofermoral and Saphenpopliteal)?
If the vein is less than 6 mm, there is a fair chance for success, but if it greater than 6 mm, about 93% reopen within 2 years.
How long does the procedure last?
The procedure is done in office and takes approximately 30 minutes.
Is it painful?
We inject a small amount of lidocaine in the area before the injection to minimize any discomfort, so that it is virtually painless. The solution itself is painless.
Are there any risks?
As with any technical procedure there is certain amount of risk. Skill, expertise, and experience are critical. Dr. Roger Murray has performed in excess of 50,000 USGI/EVCA without any serious complications. Should an artery be injected, it could cause significant sloughing of the skin above it. There is also a 1-in-10,000 chance of producing a blood clot. The only other major risk factor is an allergic reaction to the sclerosant.
Will my leg be wrapped?
Yes, with a compression stocking.
Will my activities be limited afterwards?
No. Walking immediately is strongly encouraged, along with massaging the treated vein.
Can I go back to work the next day?
Yes, you can return to work the next day and, in most cases, even the same day.
What is the recovery time, and will there be significant bruising?
Because we use local anesthesia, there is virtually no swelling immediately after the procedure. However, if there is swelling, about 70% of this swelling is usually gone by the next morning. We ask all our patients to take Arnica Montana and kiwi fruit for one week prior to the procedure and one week afterwards. This minimizes bruising to the point that in two weeks almost all the bruising is gone. Please be sure you do not take any aspirin or blood thinners for one week prior to the procedure. Make sure to discuss with Dr. Roger Murray all medications (OTC drugs, herbs, and dietary supplements) you are taking.
