Family members of Sydney Galleger announced on Monday that the Eden Prairie 17-year-old has died, after suffering complications from extraction of her wisdom teeth.
Diane Galleger wrote of Sydney in a post on her daughter's CaringBridge page: "Her faith was strong, her heart was big, her laughter was infectious and her smile could light up a room."
Sydney Galleger's complications began at the end of a normally routine medical procedure last week. Her family wrote that after extraction of her wisdom teeth, Sydney's blood pressure rose suddenly, her pulse dropped, and she went into cardiac arrest.
"We may never know the reason her heart decided to come to a rest," her family wrote on the CaringBridge page after doctors said there was nothing more they could do for Sydney.
The girls lacrosse team at Eden Prairie High School dedicated its state championship victory over the weekend to Galleger, who had finished her junior year at the school, where she was a diver and alpine skier.
While it was widely reported over the weekend that Galleger had died, her family clarified early Monday that she was still alive, saying that because she could still breathe on her own with help from a ventilator, Sydney did not meet all of the criteria for brain death.
But that changed later on Monday. Her family's CaringBridge post says a funeral will be held at St. Andrew Lutheran Church on Saturday at 11:11 a.m.
How did wisdom tooth removal turn fatal?
As the Galleger family suggested, the cause of Sydney's cardiac arrest may never be known.
FOX 9 reports family members suspect she may have had a heart condition of which they were unaware.
The professor who chairs New York University's department of oral and maxillofacial surgery tells Yahoo Parenting an adverse reaction to anesthesia could be a possibility.
Health columnist Dr. Manny writes that one of the most common risks during tooth extraction is fainting, which can lower blood pressure and lead to cardiac arrest.
The Galleger family wrote on CaringBridge, though, that doctors said Sydney's blood pressure shot up before she went into cardiac arrest.
