The New York medical examiner issued a report today on the death of Joan Rivers, saying the comedian died of “therapeutic complications” during a procedure in which she was being evaluated for “voice changes” and stomach reflux, CNN reports.
“The classification of a death as a therapeutic complication means that the death resulted from a predictable complication of medical therapy,” the report states. Rivers died Sept. 4 at age 81.
“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,” CNN reports.
The medical examiner’s office said the fatal incident occurred “during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease.”
