This animation illustrates the removal of a large metastasis deep in the brain using the Neuroendoport technique. The Neuroendoport is a tube the circumference of a dime that creates a pathway for the entire procedure.
First, a small incision is made in the scalp. Next, a small piece of bone is removed from the skull and a small incision is made in the dura, which covers the brain.
Using stereotactic imaging as a guide, the surgeon slowly inserts a needle to guide the path of the Neuroendoport. The port is slowly guided over the needle, gradually dilating the tissue around it as it travels to the base of the tumor.
An endoscope is inserted through the Neuroendoport, providing light and video images that guide the surgeon. Pressure from the tumor mass delivers the tumor into the Neuroendoport. In this example, suction is used to remove the tumor, although a variety of surgical tools may be used.
After the surgeon removes the tumor, the Neuroendoport is removed and the brain tissue returns to its original position. Next, the dura is closed with stitches; the piece of bone is replaced; and the scalp incision is stitched closed.
Because the Neuroendoport technique minimizes trauma to surrounding brain and nerve tissue, patients may benefit from fewer side effects and a shorter recovery time than with traditional surgery.
