Joan Rivers died from a lack of oxygen to her brain during a medical procedure last month to deal with changes to her voice as well as problems with acid reflex.
A report released today by the New York City Office of Chief Medical Examiner revealed that the 81-year-old entertainer sedated with Propofol during the procedure and determined what happened to be a ‘therapeutic complication.’
Melissa Rivers did not comment directly on the ruling but said in a statement:
‘We continue to be saddened by our tragic loss and grateful for the enormous outpouring of love and support from around the world.’
The procedure was taking place at Yorkville Endoscopy in New York City and Rivers’ death led to an investigation of the clinic by the state health department.
The language from the official report states the death was caused by ‘anoxic encephalopathy due to hypoxic arrest during laryngoscopy and upper gastrointestinal endoscopy with propofol sedation for evaluation of voice changes and gastroesophageal reflux disease.’
At the time of her death, Rivers was enjoying one of the busiest periods of her long career. She was host of weekly show Fashion Police, starred with daughter Melissa in a reality show, had her own web interview show, was performing stand-up dates and had authored a best-selling comedy book released during the summer.
