Interventional Radiology in Treating Hemorrhoids
Hemorrhoids are swollen blood vessels in the lower rectum and anus. They are common, and in many cases, they improve with diet changes or simple home care. When symptoms persist, treatment options range from minor office procedures to surgery. Interventional radiology offers another path.
How Interventional Radiology Works
Interventional radiology is a medical specialty that uses imaging to guide treatment. Doctors who practice it are called interventional radiologists. They rely on tools such as X-rays, ultrasound, and CT scans to see inside the body during a procedure.
These procedures are minimally invasive. Instead of large incisions, the doctor works through a small puncture, often in the groin. A thin tube called a catheter is then threaded through the blood vessels to reach the target area.
Imaging acts as a real-time map. It shows the catheter’s position and the surrounding anatomy, which allows precise treatment of a specific site. Though cases vary, full recovery can take weeks, but many patients resume normal activities after a day.
How Does It Treat Hemorrhoids
The interventional approach to hemorrhoids is called hemorrhoidal artery embolization. Embolization means blocking a blood vessel on purpose. Doctors use a catheter to inject an agent that stops blood flow to the hemorrhoid, so it shrinks over time. Surgical removal addresses the hemorrhoid tissue directly. Embolization instead targets the blood supply that feeds the problem. Both aim to reduce symptoms, but they work through different mechanisms.
Who Needs It
Not every case calls for an interventional procedure. Many hemorrhoids respond to fiber, fluids, and topical treatments. Embolization is generally considered when symptoms continue despite these measures.
Candidates often share certain features:
- Persistent rectal bleeding linked to internal hemorrhoids.
- Symptoms that have not improved with lifestyle changes or office-based treatments.
- A preference to avoid open surgery, or a medical reason that makes surgery less suitable.
- Internal hemorrhoids rather than external ones, since embolization targets the internal blood supply.
Patients with bleeding disorders or certain vascular conditions may not be suitable candidates. A full medical review can help doctors determine whether the approach fits a given case. The decision rests on the type of hemorrhoid, the severity of symptoms, and overall health.
It is worth noting that bleeding from the rectum can have many causes. A proper diagnosis must rule out other conditions before any hemorrhoid treatment begins.
How to Get Started
If your hemorrhoid symptoms have not improved with standard care, you can explore whether interventional radiology is an option for you. The process begins with information and a proper evaluation.
Start by talking with your primary care doctor or gastroenterologist about your symptoms. Ask whether a referral to an interventional radiologist is appropriate for your situation. Bring a record of treatments you have already tried.
During a consultation, you can expect a review of your medical history and possibly imaging tests. Use this visit to ask how the procedure works, what recovery involves, and what results are realistic. A thorough evaluation will confirm whether embolization suits your case before any treatment is scheduled.
