Close-up of tumour embolisation - image description

The illustration shows a close-up of tumour embolisation for kidney cancer. It shows a kidney with a tumour in its centre. To the side of the kidney is the large blood vessel that carries blood to the kidney. Inside the blood vessel is a thin catheter. The tip of the catheter sits in the blood vessel just outside the kidney. Inside the catheter are tiny embolisation beads that have been injected through the catheter to block the small blood vessels that carry blood to the tumour.
