How does a physician administer TheraSphere®?
To direct TheraSphere® treatment at tumors in the liver, a physician first makes a small incision in the patient’s leg and places a long, flexible plastic tube called a catheter, into the femoral artery, which is the major blood vessel in the leg. Guided by fluoroscopy (an X-ray imaging technique that projects views of the inside of the body onto a screen) the physician then moves the catheter up through the blood vessels to the hepatic artery, which is one of two blood vessels that feeds the liver. The physician guides the catheter into the branch of the hepatic artery that feeds the cancerous tumor in the liver and infuses the TheraSphere® beads through the catheter into the blood that supplies the tumor. This is usually performed in a hospital’s radiology suite and patients remain conscious throughout the procedure.
