The Future of Brain Surgery

With Lasers and Daring, Doctors Race to Save a Young Man’s Brain.

The idea is deceptively simple: instead of cutting a hole in the brain artery and then sewing a vein to it, he sews first and cuts later. That way, the artery does not have to be temporarily clamped, and blood flow to the brain is not cut off. A excimer laser is used to make the hole because it can be slipped into a tight space on the tip of a slender tube and makes a clean cut that stays open without burning nearby tissue.
