Joan Rivers' Death Was 'Complication' of Surgery, Autopsy Reveals
Joan Rivers' autopsy report was released on Thursday, revealing her official cause of death to be a lack of sufficient oxygen to her brain.
According to The New York City Office of Chief Medical Examiner's (OCME) investigation, the cause of Rivers' death was anoxic encephalopathy (brain damage) due to hypoxic arrest (a decrease in oxygen to the brain) during surgery -- a laryngoscopy and upper gastrointestinal endoscopy.
The report also revealed that Rivers was under propofol sedation during the procedure. Michael Jackson died from a fatal dose of propofol in 2009.
Rivers' death was classified as a "therapeutic complication," which means that the death officially resulted from a predictable complication of medical therapy.
The legendary comedienne underwent a routine endoscopy in August to evaluate changes in her voice and to deal with acid reflux. She was placed in a medically induced coma after going into cardiac arrest and passed away a week later. She was 81.
Following her death there was an outpouring of love from her peers in Hollywood.
