A 62-year-old man was admitted to this hospital with a complaint of frostbite in multiple fingers. Twenty-four days after the injury, the fingertips of seven fingers were reconstructed using a free anterolateral thigh flap harvested from one thigh, dissected into two parts. Consequent surgery involving the separation of the fingers was performed two times, 22 and 35 days after the first surgery. The patient experienced symptoms of intolerance to cold and was prescribed beraprost sodium orally, resulting in a gradual alleviation of his symptoms.
The exact point to which necrosis permeates frostbite-affected fingers is a difficult judgment in the early stages. However, debriding earlier and covering the tips with a well vascularized flap can succeed in reserving the length and function of the fingers. From this perspective, a free anterolateral thigh flap dissected into two parts is effective.
