Why Experience Matters in Embolization
Embolization procedures require specialized training and high procedural volume. Choosing an experienced interventional radiologist is critical to achieving the best outcomes.
Patients should always ask:
- How many procedures has the physician performed?
- What are their success rates and complication rates?
With decades of experience and thousands of procedures completed, Dr. Nutting is a trusted leader in embolization and minimally invasive treatments in Denver.
Prostate Embolization
Dr. Nutting has successfully treated over 1,000 patients from all across the United States through prostate embolization. He currently trains other physicians in the PAE procedure and was fortunate to receive training from luminaries of prostate embolization in Brazil and Portugal. Additionally, Dr. Nutting frequently lectures at conferences about PAE and has published research and articles on this topic.
Liver Embolization
Dr. Nutting has performed over 10,000 liver embolizations in his career making him one of the leaders in the field. As part of an interdisciplinary team, he participates in clinical trials and publishes data with other physicians around the world. He was the first physician to deliver Sirsphere radioactive microspheres in the United States in 2003.
Knee Arthritis Embolization
Dr. Nutting treats arthritic knee pain for patients who are not ready or are trying to avoid a total knee replacement. Called a Genicular Embolization, Dr. Nutting is leading the advancement of this exciting and minimally-invasive treatment as a principal investigator in a worldwide trial to treat 1000 patients over the next number of years.
Don’t be fooled
Embolization procedures require specialized training and repetition. Experience absolutely matters. It is vitally important to always ask any physician how many of your particular procedures they have personally performed. Additionally, ask for their outcomes data and complication rates.

Minimally Invasive Treatment Options
Revolutionizing the landscape of benign prostatic hyperplasia (BPH) management, our state-of-the-art embolization therapy offers a non-surgical breakthrough for individuals grappling with symptomatic BPH. This minimally invasive procedure is designed to provide targeted relief by addressing the enlarged prostate’s vascular supply.
Embarking on the forefront of interventional oncology, our cutting-edge embolization therapy stands as a beacon of hope in the battle against both primary and metastatic tumors. Meticulously designed and executed by our expert team of medical professionals, this innovative treatment approach is tailored to address the unique challenges posed by these intricate malignancies.
Genicular artery embolization (GAE) has emerged as a promising interventional radiology procedure to alleviate pain in patients suffering from knee osteoarthritis (OA). Knee OA is a common and debilitating condition characterized by the progressive deterioration of joint cartilage, leading to pain, stiffness, and functional impairment. While traditional treatments such as medications, physical therapy, and injections may provide relief, some patients continue to experience persistent pain.
Using advanced image-guided therapy, Dr. Nutting precisely blocks the blood supply to fibroids, causing them to shrink and relieving symptoms such as heavy bleeding, pelvic pain, and pressure. This outpatient procedure avoids hysterectomy, preserves the uterus, and allows for a faster recovery with minimal downtime.
Through image-guided embolization, Dr. Nutting targets the arteries supplying hemorrhoids, decreasing blood flow and reducing swelling and bleeding. This minimally invasive procedure is performed in an outpatient setting and offers a discreet, effective solution for patients seeking long-term relief.
For patients diagnosed with ocular melanoma, targeted embolization therapy offers a highly specialized, minimally invasive treatment option.
Frequently Asked Questions
What is embolization?
It is a minimally invasive, image-guided procedure that treats many conditions without major surgery. An interventional radiologist guides a thin catheter through a small puncture to block blood flow to the targeted tissue, which usually means less pain and a faster recovery than open surgery, in a same-day outpatient visit.
What conditions can it treat?
Dr. Nutting treats several conditions with embolization, including:
- Enlarged prostate (BPH) in men, through prostate artery embolization (PAE)
- Uterine fibroids, through fibroid embolization
- Knee osteoarthritis, through knee embolization (GAE)
- Liver tumors, through liver embolization
- Hemorrhoids, through hemorrhoid embolization
- Ocular melanoma, through immunoembolization
What is prostate artery embolization (PAE)?
PAE is a minimally invasive option for men with an enlarged prostate (BPH) whose urinary symptoms, such as frequent nighttime urination or a weak stream, affect daily life. Dr. Nutting has performed prostate artery embolization for more than 1,200 patients.
How do I know if it is right for me?
Embolization is well established and generally safe, and outcomes depend on the physician’s experience. Dr. Nutting is a Fellow of the Society of Interventional Radiology (FSIR) with more than 20 years of practice and thousands of procedures performed. Schedule a consultation to see if it is a fit for you.
