A woman who went into a coma after being stung by a wasp never regained consciousness and died nearly three years later, an inquest heard.
Mother-of-two Jane Murray-Obodynski, 50, was eating breakfast with her family when she was stung on the finger on 10 September 2000.
Within 20 minutes she had collapsed and was taken to hospital where her heart was restarted but she suffered brain damage.
Her husband Richard said in a statement to Westminster's Coroner's Court how initially he refused to accept the verdict of doctors that nothing could be done for his wife.
'Terrible tragedy'
He moved her to a hospital in north London where she underwent specialist oxygen treatment every day for three months.
He also tried a treatment involving administering amino acids and massage to increase oxygenation in the brain.
But during the two years and 10 months she was in coma she never responded.
Mrs Murray-Obodynski, from Brackenwood, Heath Drive, Walton on the Hill, Surrey, died on 12 July 2003.
A post-mortem report gave the cause of death as persistent vegetative state due to a cerebral infarction and anaphylactic shock.
Coroner Dr Paul Knapman, recording a verdict of misadventure, said: "What a terrible tragedy. Mercifully, these events are not at all common but that is no consolation for families such as these."
