Overview

Published with the inputs from Dr. Salal N, Specialist - Interventional Radiology, Meitra Hospital, Kozhikode

Tumour embolisation is a minimally invasive image-guided procedure used to block the blood supply to a tumor, effectively starving it of oxygen and nutrients. It is performed by an interventional radiologist using a catheter inserted through the blood vessels.

This treatment is often used for liver tumors, kidney cancers, bone metastases, uterine fibroids, and certain brain tumors, either as a standalone therapy or as preparation for surgery or radiation therapy.

What is tumour embolisation?

Tumour embolisation is a targeted treatment that involves injecting special particles or medications through a catheter into the arteries supplying a tumor. By blocking these vessels, the tumor’s growth slows or stops, and symptoms such as pain or bleeding are relieved.

When is tumour embolisation recommended?

Tumour embolisation is used in the management of:

  • Liver cancer (Hepatocellular carcinoma) or metastatic liver tumors
  • Kidney (renal) tumors
  • Bone tumors (such as metastases or benign vascular tumors)
  • Uterine fibroids (Uterine Artery Embolisation – UAE)
  • Brain tumors — as a pre-surgical step to reduce bleeding risk

It is especially beneficial for patients not eligible for surgery or those requiring tumor shrinkage before an operation.

How is tumour embolisation performed?
  • The procedure is done under local anesthesia and mild sedation.
  • A small catheter is inserted into a blood vessel, usually in the groin or wrist.
  • Using real-time X-ray guidance (fluoroscopy), the catheter is guided to the artery feeding the tumor.
  • Tiny particles, coils, or medication are injected to block the blood flow to the tumor.
  • The entire procedure usually takes 1–2 hours and does not require open surgery.
Is tumour embolisation painful?

No. The procedure is minimally invasive and generally well tolerated. Some patients may experience mild pain or discomfort for a short period after the procedure due to reduced blood flow to the tumor (known as post-embolisation syndrome). This is managed with pain relief and hydration.

Is tumour embolisation safe?

Yes. Tumour embolisation is a safe and effective procedure when performed by experienced interventional radiologists.

Possible but rare risks include:

  • Mild post-procedure pain or fever
  • Temporary fatigue or nausea
  • Rarely, non-target embolisation (avoided through advanced imaging guidance)
What is recovery like after tumour embolisation?
  • Hospital stay: Usually 1–2 days for observation
  • Rest: Advised for a few days after discharge
  • Normal activities: Resume within 5–7 days
  • Follow-up imaging (CT or MRI): Done after a few weeks to assess treatment response

Some patients may need multiple sessions, depending on tumor type and location.

What are the benefits of tumour embolisation?
    • Minimally invasive with no major surgical incision
    • Targets the tumor directly while sparing healthy tissue
    • Helps reduce pain, bleeding, and tumor size
  • Can be combined with chemotherapy (chemoembolisation) or radiation (radioembolisation)
  • Short recovery time and improved quality of life
Who performs tumour embolisation?

The procedure is performed by a specialized interventional radiologist — a doctor trained in minimally invasive, image-guided treatments of vascular and tumor-related conditions.
