Patrick Dempsey’s Heroic Rescue — CAR CRASH CARNAGE [PHOTOS]

Grey”s Anatomy” star Patrick Dempsey“s rescue mission in Malibu this week was even more badass than we thought — just take a look at the scene of the accident!!!

our sources broke the story … a teenage driver crashed and flipped his Mustang on the road right outside Dempsey”s Malibu home — and the actor came to the rescue, crowbar in hand to pry the doors open.

Dempsey successfully pulled the driver from the wreckage — a 17-year-old named Weston Massett — who tells our sources, when he opened his eyes, the actor was looking right down at him.

Massett asked, “Are you famous” … and Patrick coolly replied, “I”m a doctor.”

We”re told Patrick called Massett”s mother and told her about the accident — keeping her calm the entire time. Massett was then airlifted to a nearby hospital, and Patrick followed to make sure the kid was okay.

Miraculously, Massett suffered no serious injuries — just a concussion and a “stretched” optic nerve. He”s expected to make a full recovery.

There was also a passenger in the car, Dylan Miller, but thankfully we”re told Miller suffered no injuries whatsoever.

Wear your seat belts, kids.
