Arterial embolisation for kidney cancer
What is arterial embolisation?
Arterial embolisation is when a substance is injected into a blood vessel (artery) in the kidney, to block the blood supply to the cancer. This reduces the supply of oxygen and nutrients to the tumour, which can make it shrink or stop growing.
Arterial embolisation cannot cure the cancer by itself. But it can help control symptoms, such as pain or bleeding.
You may be offered arterial embolisation if an operation is not possible for you.
Having arterial embolisation for kidney cancer
Before treatment, the nurse or doctor usually gives you a mild sedative to help you relax. They then inject some local anaesthetic into the skin at the top of the leg (the groin) to numb the area.
A doctor puts a thin, plastic tube (catheter) into a blood vessel in the groin. Using x-ray pictures as a guide, they thread the catheter upwards until the tip is in the artery that carries blood to the area of the kidney where the cancer is.
They then inject a substance, such as tiny beads, through the catheter into the artery. This blocks the blood supply to the cancer.
Side effects of arterial embolisation for kidney cancer
This treatment can sometimes cause pain in the back. Your doctor will give you painkillers to take regularly for a few days.
You may feel a little unwell for the first few days and have a slightly raised temperature. You will probably also be tired.
Going home after arterial embolisation
After arterial embolisation, you may need to stay in hospital overnight, or possibly for a day or two longer, depending on how quickly you recover.
Your surgeon or nurse can tell you when you can start doing everyday activities again.
Before you leave hospital, you will be given an appointment for a check-up. This will be at an outpatient clinic. Your doctor or nurse may also arrange for you to have a CT scan to see the result of the treatment.
You will have regular follow-up scans to check the kidney for any signs of the cancer growing back.
