Joan Rivers died of "therapeutic complications" during a procedure to evaluate her "voice changes" and stomach reflux, the New York medical examiner said Thursday.
"The classification of a death as a therapeutic complication means that the death resulted from a predictable complication of medical therapy," the report said, according to
CNN.
The 81-year-old comedian died September 4, a week after an appointment at Manhattan's Yorkville Endoscopy clinic. The medical examiner's investigation ruled that the cause of death was "anoxic encephalopathy due to hypoxic arrest," a medical description of brain damage caused by a lack of oxygen.
The arrest happened "during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease," the medical examiner's officer said.
The initial report did not name the doctor or doctors who performed the procedures.
