Tumor Embolization using Neuro Interventional Radiology
Neurointerventional radiology is an advanced speciality which focuses on the diagnosis and treatment of various diseases of spine, head and neck. The technology provides imaging and simultaneously minimally invasive treatment of conditions such as aneurysm or stroke, which required a major surgery previously.
Brain Tumor embolization is used to close off the vessels supplying blood to a tumor, especially when the tumor is difficult or impossible to remove. When the blood supply to the tumour gets cut off completely, the tumour shrinks in size and becomes harmless.
The neuro-interventional radiologist uses x-ray imaging and a contrast material to visualize the blood vessel. He or she inserts a catheter (through a nick in the skin) into the blood vessel and advances it to the treatment site. A medical material made up of tiny particles (called an embolic agent) is inserted through the catheter and directed to the tumor. The embolic agent will block the blood vessels that supply blood to the tumor. Following embolization, the tumor is likely shrink or grow more slowly than before.
