The sudden death of Joan Rivers is still incredible to her fans. However, today, a doctor who carried out an autopsy confirmed that her death was caused by a complication that occurred during surgery, which led to lack of oxygen flow in the brain.

Joan's doctor had sedated her with Propofol to get her ready for a medical procedure. She was to undergo an investigation of voice changes and the gastroesophagel reflux disease. According to the report released from New York City Medical Examiner's office thorough Julie Bolcer, they said that the investigation is complete.

The cause of Joan's death was lack of enough oxygen that led to brain damage and it's medically known as anoxic encephalopathy. This condition was triggered by hypoxic arrest that occurred during upper gastrointestinal endoscopy and laryngoscopy with sedation done using Propof.

The Office of Chief Medical Examiner continued to say that the death was as a result of therapeutic complication, this means that the death was caused by a medical therapy complication, which was predictable.
