Mrs Smith, from Braunton, had first gone to the North Devon District Hospital in Barnstaple with persistent headaches, vertigo and numbness in the face. They were symptoms of two deadly enlarged blood vessels putting pressure on her brain.
When the aneurisms were detected, the mother-of-four was referred to Plymouth's Derriford Hospital.
Mrs Smith's daughter, Beverley Hopkins, was determined to discover what had happened with her mother's care at both the North Devon Healthcare NHS Trust and Plymouth Hospitals NHS Trust and took legal action.
"We were all devastated by her death but when I wrote to the hospital trusts and health ombudsman to find out what had happened and they tried to fob me off for two years it was another kick in the teeth.
"It generally felt they were trying to brush it under the carpet and after getting nowhere for two years I decided legal action was my only option.
