Hemorrhoid Artery Embolization (HAE)
Hemorrhoids affect millions of adults and can significantly disrupt daily life. We now offer Hemorrhoid Artery Embolization (HAE) through our Interventional Radiology (IR) Center—a non-surgical, minimally invasive option for treating symptomatic internal hemorrhoids. HAE is designed to reduce hemorrhoid symptoms while preserving normal anatomy, minimizing discomfort, and shortening recovery time.
What Are Hemorrhoids?
Hemorrhoids are swollen blood vessels located in and around the anus and rectum. They commonly develop due to:
- Chronic constipation or straining
- Prolonged sitting
- Pregnancy or childbirth
- Heavy lifting
- Aging
Symptoms may include:
- Rectal bleeding
- Pain or discomfort
- Itching or irritation
- A feeling of fullness or pressure
Treatment Options
When diet changes, fiber supplements, or medications don’t provide relief, treatment options for chronic internal hemorrhoids may include:
Rubber band ligation – first-line outpatient procedure, often with less durable results
Hemorrhoidectomy – in-patient surgical procedure that includes risks, complications and a difficult recovery
Hemorrhoid artery embolization (HAE) – minimally invasive procedure for patients with grade 1 to 3 internal hemorrhoids that offers comparable results with less pain and a shorter recovery


What is Hemorrhoid Artery Embolization (HAE)?
Hemorrhoid Artery Embolization (HAE) is a non-surgical, minimally invasive option for treating HAE, designed to reduce hemorrhoid symptoms while preserving normal anatomy, minimizing discomfort, and shortening recovery time.
HAE is a catheter-based procedure performed by an interventional radiologist. Rather than removing hemorrhoids surgically, HAE targets and reduces the blood flow to the hemorrhoid tissue, causing it to shrink over time.
- A tiny catheter is inserted through an artery in the wrist or groin
- Using real-time imaging, the catheter is guided to the arteries supplying the hemorrhoids
- Microscopic embolization particles are used to reduce blood flow to hemorrhoid tissue
- The procedure typically takes about one hour. Patients return home the same day
Because the rectum has multiple blood supplies, normal tissue remains healthy while hemorrhoid symptoms improve.
Advantages of HAE
- Minimally invasive (no incisions or stitches)
- No general anesthesia required
- Preserves anal continence
- No rectal wounds
- Less post-procedure pain compared to surgery
- Short recovery time
- Return to normal activity in days not weeks
- High success rates for bleeding and symptom relief
Greater than 90% success rate for this procedure.
