Many patients come to my office expecting that a blocked artery or a bad vein means a large incision and a long hospital stay. Often, that is no longer the case. Interventional radiology is a medical specialty that uses live imaging to guide tiny instruments through the blood vessels, so problems can be treated from the inside. As a board-certified interventional radiologist, I want to explain what this field is, how the procedures work, and which conditions it can treat.
Key Takeaways
- Interventional radiology treats many conditions through a tiny puncture in the skin, guided by X-ray or ultrasound.
- Common uses include PAD, varicose veins, uterine fibroids, and dialysis access problems.
- Most procedures use local numbing and light sedation instead of general anesthesia.
- Recovery is usually shorter than with open surgery, and most patients go home the day of the procedure.
What Is Interventional Radiology?
Radiology is the branch of medicine that uses imaging, such as X-ray, ultrasound, CT, and MRI. Interventional radiologists take this a step further. Instead of only taking pictures, we use those images in real time to guide treatment.
In practice, that means I can see inside your blood vessels while I work. So rather than opening the leg to reach a blocked artery, I make a small puncture, often in the groin or wrist. Then I guide a thin, flexible tube called a catheter to the problem area. Through that catheter, I can open a narrowed artery, place a stent, close a leaky vein, or block blood flow to a fibroid.
Interventional radiologists complete medical school, a radiology residency, and further training in image-guided procedures. The Society of Interventional Radiology offers more background on the specialty for patients.
How Image-Guided Procedures Work
Depending on the procedure, I may use several kinds of imaging:
- Ultrasound to see veins and arteries under the skin and guide the first needle safely
- Fluoroscopy, a type of live X-ray, to watch the catheter move through the blood vessels
- Angiography, which uses contrast dye to map blood flow and show exactly where a blockage is
Because the procedure is done through a small puncture, most patients need only local numbing medicine and light sedation. As a result, there is less strain on the body than with a long operation under general anesthesia. Afterward, the puncture site usually needs only a small bandage.
Conditions Treated With Interventional Radiology
Peripheral Artery Disease (PAD)
With PAD, plaque narrows the arteries to the legs. This can cause cramping with walking, rest pain, and wounds that will not heal. To restore blood flow, I may use angioplasty, which opens the artery with a small balloon. In some cases, I also place a stent to help keep it open, or use atherectomy to remove plaque from inside the artery. For more detail, see my article on how PAD is treated without open surgery.
Varicose Veins and Venous Insufficiency
When vein valves fail, blood pools in the legs and causes aching, swelling, and varicose veins. With radiofrequency ablation, I place a thin catheter inside the faulty vein and use gentle heat to close it. Blood then reroutes through healthy veins. Smaller veins can often be treated with sclerotherapy, a series of small injections.
Uterine Fibroids
Uterine fibroid embolization (UFE) treats fibroids by blocking the small arteries that feed them. Over time, the fibroids shrink, and symptoms such as heavy bleeding and pelvic pressure often improve. For many women, UFE offers an alternative to hysterectomy.
Dialysis Access and Blood Clots
For patients on dialysis, I help keep fistulas and grafts working through dialysis access management. In addition, I evaluate and treat patients with deep vein thrombosis and its long-term effects on the legs.
What About Heart Patients?
Patients with heart disease often ask whether these techniques can help them, too. Blockages in the heart's own arteries are treated by cardiologists, who use similar catheter-based methods. However, heart patients frequently have plaque in their leg arteries as well. In fact, PAD is a strong warning sign that the heart and brain arteries may also be affected.
For these patients, a less invasive approach can be especially helpful. A long operation under general anesthesia puts extra stress on a heart that is already working hard. In contrast, most of my procedures use light sedation and take far less time. I also work closely with your cardiologist and primary care doctor, so your whole care team stays on the same page.
Benefits Compared With Open Surgery
For the right patient, image-guided treatment offers real advantages:
- No large incision, so there is usually less pain and scarring
- Local numbing and light sedation in place of general anesthesia for most procedures
- A lower risk of wound infection
- A faster return to normal activities for most patients
That said, every procedure carries some risk, and not every problem is best treated this way. For example, some long or complex blockages are better treated with bypass surgery. In those cases, I work with surgical colleagues so you get the right care. You can learn how the two specialties compare in my article on interventional radiologists vs. vascular surgeons.
What to Expect at Coastal Vascular Center
Your care starts with a conversation, an exam, and simple tests such as an ultrasound or an ankle-brachial index test. Next, I explain what the results mean and walk you through every option, including treatments that do not involve a procedure at all. If a procedure makes sense, I explain how to prepare, what happens that day, and what recovery looks like.
Coastal Vascular Center is a small, locally owned practice, not a corporate chain. You see me at every visit, and I personally perform every procedure. There is no hand-off to a physician assistant or nurse practitioner, so the doctor you meet at your first visit is the doctor who treats you.
