Iranian surgeons treating wounded Iranian veterans during the Iran–Iraq War invented a new neurosurgical treatment for brain injured patients that laid to rest the previously prevalent technique developed by US Army surgeon Dr Ralph Munslow. This new surgical procedure helped devise new guidelines that have decreased death rates for comatosed patients with penetrating brain injuries from 55% of 1980 to 20% of 2010. It has been said that these new treatment guidelines benefited US congresswoman Gabby Giffords who had been shot in the head.
