Local neurosurgeon on White Sox player’s aneurysm — what happens when a brain bleeds?

CHICAGO -- White Sox relief pitcher Danny Farquhar remains in critical but stable condition at Rush University Medical Center after suffering a ruptured brain aneurysm mid-game.

It was during Friday night's home game that Farquar recorded the last two outs of the 6th during a relief string. He launched 15 pitches, returned back to the dugout, and collapsed a short time later.

The White Sox said he regained consciousness before an ambulance took him from Guaranteed Rate Field to the hospital.

While he's not treating Farquhar, Dr. Shakeel Chowdhry, a neurosurgeon at NorthShore University Health System, stopped by WGN Morning News to explain what exactly happens when a brain bleeds. Check out his interview in the player above.
