Medical examiners have found that comedy great Joan Rivers officially died from “predictable” complications due to surgery.
The New York City Medical Examiner's Office released their report on Thursday, saying that while Rivers was sedated with propofol for a throat procedure, she died from hypoxic arrest, which cut off oxygen to her brain.
The report also said that Rivers was undergoing the procedure to evaluate “voice changes and gastroesophageal reflux disease.”
The whole statement read, "OCME [Office of the Chief Medical Examiner] has completed its investigation. The cause of Ms. Rivers' death is anoxic encephalopathy due to hypoxic arrest during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease. The manner of death is therapeutic complication. The classification of a death as a therapeutic complication means that the death resulted from a predictable complication of medical therapy."
Melissa Rivers said in a statement to The Hollywood Reporter, "We continue to be saddened by our tragic loss and grateful for the enormous outpouring of love and support from around the world. We have no further comment at this time."
