Hemorrhoidal artery embolization (HAE) is a minimally invasive treatment that can reduce the symptoms of internal hemorrhoids, such as rectal bleeding, discomfort, and swelling. Performed by double board-certified diagnostic and interventional radiologists Dr. Rajiv Srinivasa and Dr. Taylor Maloney, this outpatient procedure targets the blood supply feeding hemorrhoids, offering relief without open surgery.
Overview
Hemorrhoidal artery embolization (HAE) is a minimally invasive procedure that reduces internal hemorrhoid symptoms by blocking the arteries that supply excess blood to the swollen tissue. Using imaging guidance, your physician inserts a tiny catheter into a blood vessel and releases microscopic particles to restrict blood flow to the hemorrhoids. As blood flow decreases, the hemorrhoidal tissue gradually shrinks, helping alleviate bleeding, discomfort, and pressure. HAE offers lasting relief without surgery and minimal downtime.
Hemorrhoidal Artery Embolization (HAE) Treats
Hemorrhoidal artery embolization (HAE) treats internal hemorrhoids that cause persistent discomfort and interfere with daily life. By reducing the blood supply to enlarged hemorrhoidal tissue, HAE helps improve symptoms that many patients find difficult to manage with conservative treatments. It can help with symptoms such as:
- Ongoing rectal bleeding
- Painful swelling or fullness in the rectal area
- Irritation or itching around the anus
- Difficulty sitting comfortably due to hemorrhoid pressure
- Discomfort during or after bowel movements
How Hemorrhoidal Artery Embolization (HAE) Works
Hemorrhoidal artery embolization (HAE) reduces excess blood flow to internal hemorrhoids, swollen veins inside the rectum. Using fluoroscopic imaging, your physician guides a tiny catheter into the arteries feeding the hemorrhoids. Microscopic particles are then released to block these vessels, limiting blood supply to the enlarged tissue. With less blood flow, the hemorrhoids shrink over time. Because the procedure targets the arteries directly, it avoids cutting or removing tissue and supports a quicker recovery.
Advantages of Hemorrhoidal Artery Embolization (HAE)
Hemorrhoidal artery embolization (HAE) offers meaningful benefits for patients seeking relief from hemorrhoid symptoms without surgery. By targeting the underlying blood supply, this technique provides lasting improvement with minimal discomfort. Key advantages of hemorrhoidal artery embolization (HAE) include:
- Reduced bleeding and swelling at the source of the hemorrhoids
- Minimal pain compared to conventional surgical treatments
- No need for incisions or removal of tissue
- Quicker recovery and faster return to normal activities
- Lower risk of complications and postoperative discomfort
- Preservation of normal anal function and continence
Is Hemorrhoidal Artery Embolization Painful?
Patients typically experience minimal discomfort during HAE. The procedure is performed using local anesthesia and light sedation, so most people remain relaxed and comfortable. Afterward, some may notice mild pelvic pressure or temporary soreness, but this is usually far less intense than the discomfort associated with surgical hemorrhoid removal.
Hemorrhoidal Artery Embolization (HAE) FAQs
How Long Does Hemorrhoidal Artery Embolization Take?
The procedure generally lasts 45 to 90 minutes, depending on the complexity of your anatomy and the number of arteries that need to be treated. After a short monitoring period, patients can usually go home the same day, making HAE a convenient outpatient treatment.
Who is a Good Candidate for HAE?
HAE is ideal for individuals with persistent internal hemorrhoids that do not respond to conservative treatments such as dietary changes, fiber supplements, topical creams, or rubber-band ligation. It is especially beneficial for patients who experience ongoing rectal bleeding or discomfort but want to avoid surgery. Your physician will review your medical history, symptoms, and imaging studies to determine if HAE is appropriate for you.
How Long Does It Take to See Results After HAE?
Many patients begin noticing symptom improvement within days to weeks. Bleeding often decreases first, followed by a gradual reduction in swelling, pressure, and discomfort as the hemorrhoidal tissue shrinks. The full benefits may continue to develop over several months.
Are There Risks or Side Effects?
HAE is considered safe, with a lower complication rate than surgical hemorrhoid procedures. Mild temporary side effects may include pelvic discomfort, constipation, or spotting. Rare complications involve non-target embolization or infection, but these are uncommon when performed by experienced interventional radiologists.
Can Hemorrhoids Return After HAE?
While HAE reduces blood flow to treated hemorrhoids, recurrence is possible if new blood vessels develop or lifestyle habits contributing to hemorrhoids persist. Maintaining a high-fiber diet, staying hydrated, and maintaining healthy bowel habits can help prolong results.
