If you have noticed rectal bleeding and have been diagnosed with internal hemorrhoids, you are far from alone. Studies show that nearly half of all adults experience hemorrhoids by the age of 50. While common, hemorrhoids can cause significant discomfort, itching, bleeding, and emotional distress.
Fortunately, modern medicine offers effective treatment options that do not require surgery. One such option is hemorrhoidal artery embolization, a minimally invasive procedure designed to treat the underlying cause of internal hemorrhoids with minimal downtime.
What Are Hemorrhoids?
Hemorrhoids are normal vascular structures located in the anal canal. In healthy conditions, they contribute to continence by helping seal the anal opening. Problems arise when these veins become enlarged or swollen, leading to symptoms.
Common symptoms of hemorrhoids include:
- Rectal bleeding during bowel movements
- Itching or irritation around the anus
- Pain or discomfort with defecation
- Swelling or palpable lumps near the anal opening
Beyond physical symptoms, hemorrhoids can negatively affect emotional well-being. Many people feel embarrassed or hesitant to seek care, which can delay effective treatment and worsen symptoms over time.
What Causes Hemorrhoids?
Hemorrhoids typically develop due to increased pressure in the lower rectum. This pressure causes veins to stretch and swell. Contributing factors may include:
- Straining during bowel movements
- Prolonged sitting, especially on the toilet
- Chronic constipation or diarrhea
- Obesity
- Pregnancy
- Low-fiber diet
- Heavy lifting
- Certain lifestyle habits
If left untreated, hemorrhoids can interfere with daily activities, work performance, relationships, and overall quality of life.
Hemorrhoidal Artery Embolization: A Modern Treatment Option
Hemorrhoidal artery embolization is a minimally invasive procedure used to treat bleeding from internal hemorrhoids. Rather than removing hemorrhoids surgically, this technique reduces their blood supply, allowing them to shrink naturally over time.
Using advanced imaging guidance, a small catheter is navigated through the blood vessels to the arteries supplying the hemorrhoids. Tiny coils or embolic materials are then deployed to limit blood flow. As circulation decreases, hemorrhoidal tissue gradually shrinks and bleeding resolves.
Key Advantages of Hemorrhoidal Artery Embolization
Minimally Invasive
The procedure is performed through a small puncture, typically in the groin or leg, without large incisions. No cutting or removal of hemorrhoidal tissue is required.
Faster Recovery
Because there are no surgical wounds or stitches, recovery is quick. Most patients return to normal activities within a day, without the prolonged downtime associated with hemorrhoid surgery.
Long-Lasting Symptom Relief
Many patients experience significant improvement in bleeding and discomfort shortly after treatment. Results are durable and achieved without major complications.
Lower Risk Profile
Since the anal canal is not surgically manipulated, the risks of infection, pain, and prolonged healing are significantly reduced compared to traditional hemorrhoidectomy.
What to Expect During the Procedure
Hemorrhoidal artery embolization is typically performed under local anesthesia. A small catheter is inserted into an artery and guided, using real-time imaging, to the blood vessels supplying the hemorrhoidal tissue.
Internal hemorrhoids are fed by branches of the superior rectal artery within a vascular network known as the corpus cavernosum recti. Once the catheter reaches these vessels, embolic coils are released to reduce blood flow, addressing the root cause of bleeding.
The procedure does not require general anesthesia and is usually completed in a short outpatient visit.
Recovery and Results
Recovery following hemorrhoidal artery embolization is generally quick and uncomplicated. Because there is no direct trauma to the rectum or anus, discomfort is minimal. Most patients can resume work and daily routines the next day.
Clinical data shows that more than 90 percent of patients experience a significant reduction in hemorrhoidal bleeding after treatment. While individual results may vary depending on severity, many patients achieve lasting symptom relief after a single procedure.
