Tumor Embolization:

Tumors of the head and neck may have abundant arterial blood supply. Such tumors can be difficult to remove surgically without incurring significant blood loss.  Using angiographic techniques, it is possible to inject the arteries which feed a tumor with a substance that closes the vessels prior to surgery. This process, called tumor embolization is performed by the neurointerventional doctors at Saint Luke's Hospital of Kansas City.

Tumor embolization is performed in the neurointerventional suite while a patient is under anesthesia. First, a diagnostic angiogram of the tumor area is performed. Once the site of tumor is identified, a microcatheter is advanced to the tumor and particles or a pharmaceutical glue is injected to permanently close the blood vessels of the tumor. Surgical removal of the tumor is usually performed by a ENT or neurosurgeon the following day.
