Radiofrequency Ablation (RFA)
Today, a less invasive and highly precise treatment is available to shrink and remove benign thyroid nodules without scars, general anesthesia or hospitalization. Our interventional radiologists can remove the nodule, using heat to spark a reaction that shrinks the nodule tissue. This is a precise treatment that targets only the nodule, without damaging the surrounding healthy tissue or compromising normal thyroid functions.
Radiofrequency Ablation (RFA): Thyroid Treatments FAQs
Before the ablation, the patient lies down on a comfortable table with a mild neck extension (chin up). A grounding pad is attached to the thigh. It may be necessary to shave the hair on the thigh to properly place the pads. The neck is cleaned and towels and drapes are placed over your body. A thorough ultrasound exam is done examining the thyroid nodule. The skin over the thyroid is numbed with numbing medicine. The ablation needle is then placed into the nodule and adjusted multiple times to treat as much of the nodule as possible. The needle is removed and a bandaid and ice pack will be placed on your skin. The procedure itself will last about 30 minutes, and an additional hour will be required after the procedure for monitoring if you received sedation.
You must not eat or drink most beverages 8 hours prior to your procedure. You can drink clear liquids until 2 hours prior to the procedure but have no food or drinks of any kind within two hours of your procedure. Also, please do not wear makeup, lipstick or any jewelry on the day of your procedure. This procedure can be safely done without sedation, which would minimize restrictions prior to your procedure.
We will review the list of your medications and give you instructions or recommendations. In most cases, your medications will not affect the procedure.
If you are anxious, we can provide an anti-anxiety medication 30 minutes prior to the procedure. You will not be able to drive a car, so please arrange to have someone drive you to and from the procedure. We can discuss using deeper sedation as well, which will come with more pre- and post-procedure restrictions such as the need for earlier arrival, an empty stomach, a chaperone to drive and stay with you and recovery for at least 1 hour after the procedure.
Please inform your doctor if you have a pacemaker, and implants or implanted devices, are pregnant, are on medications (especially blood thinners).
After thyroid treatments, you can return to your regular daily activities as soon as you leave our center. You can walk or drive so long as no sedatives have been given.
Unless you have pain or have signs of an infection, you will not need any special medication. If you currently take medication, you will be able to resume taking them at any time after your procedure.
Thyroid Artery Embolization
Reserved for patients with large thyroid goiters and thyroid nodules >6 cm. In this procedure, our doctors put tiny particles into the blood vessels that supply blood to the thyroid gland. These particles block the blood flow to certain parts of the thyroid. This can help shrink the thyroid if it’s too big or reduce the activity of the thyroid if it’s making too much hormone. The procedure is done through a small tube called a catheter, which is inserted into a blood vessel in the leg or arm and guided to the thyroid arteries.
In addition to being safer for the patient, these minimally invasive interventional radiology techniques are less expensive than surgery and are performed on an outpatient basis, with the ability to return home the same day as the procedure. It’s a less invasive option compared to surgery and can be a good choice for people who may not be able to have surgery or prefer less invasive thyroid treatments.

Thyroid Artery Embolization: Thyroid Treatments FAQs
Thyroid artery ablation is a minimally invasive (non-surgical) procedure that uses heat to shrink benign thyroid nodules. If you’re tired of living with a visible lump, discomfort, or swallowing problems, this treatment can significantly improve your quality of life—without the downsides of surgery. Our patients often appreciate getting back to their daily routines quickly and without a scar, enjoying a more comfortable life. At North Star, we take pride in providing an advanced solution that helps you feel better sooner.
North Star Vascular and Interventional physicians use advanced ultrasound guidance to precisely deliver heat through a fine needle, targeting only the nodule and sparing the rest of your thyroid. This causes the nodule to shrink while keeping your thyroid functioning normally. It’s a great choice for those with non-cancerous nodules who want effective and gentle thyroid treatments without the stress of surgery. At your consultation, our doctors—who are pioneers in these techniques—will evaluate your condition and help you determine the best thyroid treatments for you. Your well-being is our top priority.
Unlike surgery, embolization doesn’t require general anesthesia or leave a scar, and recovery time is minimal—often just a day or two. Most importantly, it helps preserve normal thyroid function, so you can avoid lifelong medication. With our team’s unmatched expertise and our patient-centered approach, you can trust that you’ll receive the safest and most effective care and thyroid treatments possible. Our patients appreciate the quicker recovery and the freedom to return to their lives with minimal disruption.
When you arrive, our friendly staff will ensure you feel comfortable and at ease. During the procedure, you’ll be awake but won’t feel any pain thanks to local anesthesia. We use a tiny needle to deliver heat to the nodule, guided by real-time ultrasound, so everything is precise and safe. The procedure typically takes 30-60 minutes, and you can rest briefly before heading home. At North Star, we focus on making your experience smooth and stress-free from start to finish.
Most of our patients report only feeling a small pinch when we apply the numbing medicine. After that, you might feel a bit of pressure, but it’s usually quite manageable. Our caring team is always there to ensure you’re comfortable and relaxed throughout. We’re committed to making your experience as painless and pleasant as possible.
Recovery is quick—you can usually resume most of your regular activities the very next day. Just avoid heavy lifting or strenuous exercise for a couple of days. Our patients love that they can get back to life without missing a beat. Our goal is to help you feel like yourself again, without the hassle.
Many patients notice improvement within a month after thyroid treatments, with nodules continuing to shrink over 3-6 months. Most enjoy long-lasting relief, and we provide regular follow-up to monitor your progress and ensure the best results. We’re with you every step of the way to make sure you get the most out of your thyroid treatments.
While thyroid nodule embolization is very safe, minor risks like slight bleeding or temporary voice changes can happen. Our experienced doctors take every precaution to minimize these risks, and we discuss all possible outcomes with you beforehand so you’re fully informed. At North Star, you can feel confident knowing that your safety is our top priority.
There’s a small chance (10-15%) that a nodule might grow back over time after thyroid treatments. The good news is that a repeat ablation can be done easily if needed. We’ll guide you through every step to keep your thyroid health on track. Our goal is to provide ongoing support and care, so you can continue to feel your best.
No, embolization targets only the nodule, leaving the rest of your thyroid untouched. Your thyroid should continue to function normally, and we’ll monitor your thyroid levels after the procedure to make sure everything stays on track. We’re here to keep your thyroid health in balance.

We’ll provide you with all the details you need ahead of time, and our team is here to answer any questions. We aim to make everything as straightforward and easy as possible for you.
Insurance coverage can vary, but our team will help you navigate the process. We’ll work closely with your provider to determine what’s covered and guide you through any necessary steps. At North Star, we’re committed to helping you focus on your health—not the paperwork.
