What Is Hemorrhoid Embolization (HAE)?

Hemorrhoid embolization or hemorrhoidal artery embolization (HAE) is a relatively sensitive technique performed by an interventional radiologist to treat internal hemorrhoids by preventing blood flow. This is a new approach that does not require the elimination of tissue but entails a catheter-assisted procedure of obstructing the arteries that serve the swollen hemorrhoidal vessels in a manner that they will naturally shrink as the procedure continues. HAE is a non-surgical procedure used to treat hemorrhoids with a high rate of symptom relief with less pain, no incision and minimal time of recovery.

Understanding Hemorrhoids and Their Causes

Internal hemorrhoids occur due to increased pressure in the rectal veins, lifting, constipation, pregnancy and sitting. The distended veins can cause bleeding, pain, itching or prolapse.

How Hemorrhoidal Artery Embolization Works

HAE is a procedure that slows down blood circulation to the internal hemorrhoids, obstructing some of the blood vessels with small embolic spheres or coils. The bleeding and discomfort are also minimized because the hemorrhoidal tissue shrinks as the blood flow decreases.

Who Performs the Procedure (Interventional Radiologist)

HAE is done by a board-certified interventional radiologist, who is trained in image-guided interventional vascular therapies or interventions, with the use of high-tech angiography, catheter navigation, and targeted embolization.

Conditions Treated with Hemorrhoid Embolization

Hemorrhoid embolization treatment is particularly effective in treating internal hemorrhoids, especially those leading to the onset of chronic rectal bleeding, prolapse, itch or discomfort. It is also prescribed frequently in cases where other medications, including topical medicines, rubber band ligation, lifestyle interventions, or non-surgical procedures have failed to work on patients. HAE also serves the purpose of people who do not want to undergo surgery or are not capable of having the traditional hemorrhoidectomy because of medical conditions or because of increased risks of surgery.

Signs You May Need Hemorrhoid Treatment

Hemorrhoid embolization therapy is a condition that is specifically used in cases of internal hemorrhoids, especially where the condition does not subside despite conservative approaches. It is a non-surgical and advanced form of hemorrhoid treatment that is most effective in a patient when the bleeding or prolapse of the hemorrhoid is due to an excess supply of blood to the hemorrhoidal cushions. The process is expected to reduce the size of the arteries that feed the veins and, consequently, cause a reduction in symptoms.

You may benefit from hemorrhoid embolization if you have one or more of the following conditions:

• Relentless internal hemorrhoidal bleeding and bright-red rectal bleeding in particular

• Internal hemorrhoids that cannot be treated using medications, lifestyle changes and fibre therapy, or treatments like rubber band ligation

• Common or persistent hemorrhoidal issues, such as swelling, pain, or congestion

• Prolapsed internal hemorrhoids, which protrude during bowel movements

• Hemorrhoids in patients who are unable to undergo surgical procedures, such as those with comorbid medical conditions or an increased risk of surgery

• Reoccurrence of the symptoms of hemorrhoids following past treatments and procedures

• Patients who want to have a non-surgical procedure that is less painful, requires less time to recuperate and does not involve any removal of tissues

Because HAE avoids incisions and general anesthesia, it is an excellent option for patients who desire a modern, minimally invasive approach performed by a specialized interventional radiology team.

How Hemorrhoid Embolization Works

Step 1: Diagnostic Imaging (Angiography)

It starts with angiographic studies, which are carried out to locate the arteries which supply blood to the hemorrhoidal tissue. The mapping provides accurate targeting in embolization.

Step 2: Catheter insertion and Artery Mapping

The insertion is done through a small catheter into an artery, either in the wrist or in the groin. The interventional radiologist steers the catheter to the hemorrhoid supply branches by use of real-time imaging.

Step 3: Blocking the Hemorrhoidal Arteries

Micro-coils or embolic particles are introduced in order to seal off the hemorrhoidal arteries. This makes the blood flow slow down, the swollen veins shrink, and the symptoms disappear.

Step 4: Post-Procedure Recovery and Observation

The patients are observed short-term after embolization, and most of them go home on the same day. Mild pelvic or rectal discomfort can be experienced, but it usually goes away quickly.

Who Is an Ideal Candidate for Hemorrhoid Embolization

Ideal candidates include individuals with symptomatic internal hemorrhoids, especially those with chronic bleeding or prolapse, who want a non-surgical hemorrhoid treatment with minimal downtime. HAE is also suitable for patients who are not good candidates for surgery due to medical conditions, those who prefer a less painful alternative, and individuals who have experienced recurrence after traditional treatments.

Benefits of Hemorrhoid Embolization

Patients benefit from HAE because it:

• Offers a non-surgical procedure for hemorrhoids that does not require any surgical incision

• Provides a quick relief from bleeding and pain

• Permits the same-day discharge and rapid recovery to everyday activities

• Avoids general anesthesia

• Significantly reduces pain compared to traditional surgical options

• Has low complication and recurrence rates

• Preserves normal anorectal function

• It is performed by a specialized hemorrhoid embolization doctor using advanced vascular techniques

Recovery After Hemorrhoid Embolization

The recovery is normally rapid and painless. The majority of patients develop mild pelvic pressure, slight rectal discomfort or momentary alterations in bowel patterns, which resolve themselves in a few days. Normal operations can be regained generally within 24-48 hours. Symptom improvement, particularly the decreasing rectal bleeding, is frequently observed a few days later and is enforced further as the hemorrhoidal tissue contracts over the next few weeks. Follow-up sessions ensure recovery, disappearance of symptoms, and appropriate vascular reaction.

Hemorrhoid Embolization vs. Traditional Hemorrhoid Surgery

Feature	Hemorrhoid Embolization (HAE)	Traditional Hemorrhoid Surgery (Hemorrhoidectomy / Stapled Procedure)
Invasiveness	Minimally invasive, catheter-based	Surgical cutting or stapling of tissue
Anesthesia	Local anesthesia with light sedation	General or regional anesthesia
Incisions / Tissue Removal	No incisions and no tissue removal	Requires surgical incision and removal of hemorrhoidal tissue
Pain Level After Procedure	Typically mild discomfort	Moderate to severe postoperative pain is common
Bleeding Control	Targets and blocks hemorrhoidal arteries to reduce blood flow	Removes hemorrhoids directly but may involve more bleeding during recovery
Recovery Time	1–3 days for most activities	1–2 weeks or longer before full activity
Return to Work	Often within 24–48 hours	Usually requires several days to weeks
Risk of Complications	Lower risk; fewer wound-related issues, no open surgical site	Higher risk of pain, bleeding, infection, stenosis, or urinary retention
Recurrence Rate	Low recurrence when arteries are successfully embolized	Recurrence is possible, especially for prolapsed hemorrhoids
Scarring	No external scarring	Surgical scar at the site of tissue removal
Ideal for	Internal hemorrhoids, especially chronic bleeding or persistent symptoms	Severe prolapse or hemorrhoids requiring tissue removal
Setting	Outpatient procedure	Often outpatient, but may require longer observation

Risks and Side Effects

HAE is deemed to be safe, though there are minor transitory side effects, including light pelvic discomfort and mild rectal pressure, or temporary alterations of bowel habits. Other rare complications are non-target embolization, infection or allergic reaction to contrast dye. All these risks can be significantly reduced when the practice is carried out by an expert interventional radiologist who has experience in treating hemorrhoids using interventional radiology.

Success Rate and Clinical Outcomes

The success rates of hemorrhoidal artery embolization are reported as high in clinical studies, with most patients reporting a large decrease in bleeding, discomfort and symptoms of prolapse. A significant number of patients can obtain permanent improvement with no surgical intervention. It is also a good non-surgical remedy for hemorrhoids, with the procedure showing a high level of patient satisfaction and minimal recurrence.
