Hemorrhoid Embolization

What are hemorrhoids?

Hemorrhoids are swollen veins in the lower rectum or anus that can cause discomfort, pain, and bleeding. They can be internal (inside the rectum) or external (under the skin around the anus).

What causes hemorrhoids?

Hemorrhoids can be caused by a variety of factors, including increased pressure during bowel movements, pregnancy, obesity, prolonged sitting, and a low-fiber diet. Straining and chronic constipation or diarrhea can also contribute.

Why should I get them treated?

Treating hemorrhoids can relieve pain, bleeding, and discomfort, improve quality of life, and prevent complications such as thrombosis (blood clots) or infection.

What is hemorrhoid arterial embolization?

Hemorrhoid arterial embolization is a minimally invasive procedure that targets the blood vessels supplying the hemorrhoids. By blocking these vessels, the procedure reduces blood flow to the hemorrhoids, leading to their shrinkage and symptom relief.

How is this different from surgery?

Unlike traditional surgical options, which may involve cutting or removing hemorrhoids, HAE is less invasive and generally has a shorter recovery time. It can often be performed on an outpatient basis.

Is the procedure painful and what will my recovery be like?

Most patients experience minimal discomfort during and after the procedure. Recovery is typically quick, with many people returning to normal activities within a few days. Some mild pain or discomfort may occur, but this can usually be managed with over-the-counter pain relievers.

Is this a new procedure?

HAE is a relatively newer approach compared to traditional surgical methods. While it has been used for several years, it is still gaining acceptance in clinical practice.

What are my alternatives?

Alternatives include dietary changes, topical treatments, rubber band ligation, sclerotherapy, and surgical options like hemorrhoidectomy. The choice depends on the severity of symptoms and individual patient factors.

Is there scientific evidence available?

Yes, there is growing scientific evidence supporting the effectiveness of hemorrhoid arterial embolization. Studies indicate it can significantly reduce symptoms and improve quality of life for patients with hemorrhoids.

What are the risks and potential complications?

While HAE is considered safe, risks may include minor complications such as bleeding, infection, or discomfort. Rarely, more serious complications can occur, like necrosis of surrounding tissues or recurrence of hemorrhoids.

If you’re considering this procedure, it’s essential to discuss your specific situation and any concerns with your healthcare provider.
