James Valentine was in a tree on Monday afternoon when he was struck in the neck by the chain saw. Another worker helped him down, and his co-workers left the saw in place to try to limit the bleeding.
Valentine had emergency surgery. Doctors say the saw missed major arteries and, instead, cut into muscle. A hospital released an X-ray Tuesday showing the saw still in the 21-year-old's neck.
Valentine works for a tree removal service. Its owner, Dominic Migliozzi, calls the rescue ''amazing.''
