Treatment of severe frostbite with iloprost in northern Canada

Usual approach to treating severe frostbite may be insufficient to prevent necrosis, with amputation often the only solution. Authors describe two cases that occurred during the Yukon Arctic Ultra race, in which iloprost, a vasodilator, was used to treat severe frostbite with good results. Case 1, 46-yr-old man with grade 3 frostbite on his right hand. Case 2, a 43-yr-old man with grade 3 frostbite on his right foot.
