For most, summer is a time for enjoyment. Perhaps you’ve rejoiced in a recent graduation, a vacation on the horizon or just the warm, beach-perfect weather.

Here at Columbia University Medical Center/NewYork-Presbyterian Hospital, our summer has kicked off with share-worthy stories and accomplishments.

1. Gamma Knife Center Treats 4,500th Patient

The Gamma Knife, despite its name, is not a knife and doesn’t make a literal cut. It is a machine that focuses beams of gamma radiation on the targeted area in the brain. The Gamma Knife is a good alternative to surgery in carefully selected cases because most patients can go home the same day as the procedure, often heal faster and are less likely to get an infection.

Also, the Gamma Knife can treat areas of the brain that cannot be safely reached during surgery. And Columbia was one of the first in the area to bring this technology to patients. Brain tumors, arteriovenous malformations (blood vessel disorders), epilepsy and more are all on the Gamma Knife’s list of treatable conditions.

Dr. Michael B. Sisti is director of the Gamma Knife Center, and he and his team are celebrating their most recent milestone: treating their 4,500th patient!

2. New York City at the Dawn of Neurosurgery

New York City holds a rich history for neurosurgery. It is the home of several “firsts,” one being the first place brain tumor surgery was attempted in the United States.

In an article published in the Journal of Neurological Surgery, Department Chair Dr. Robert Solomon takes readers back to when neurosurgery was born—before the advances and knowledge we use today. He explains that much of the legacy of neurosurgery resides within the walls of our home, Columbia.
