[|Human|] Hi my name is cathy, my husband is in a nursing home he has liver failuer, and bed sores, but when we go see him we always take pictures of something different, now on his left toe nail the big toe its all black under the nail, my daughter tried to cut the nail and she said the nail was dead, what does this mean, he can t walk so he did not hit it.
[|AI|]  Hi, Welcome to Chat Doctor forum.  As he has liver failure, there is a possibility of the circulatory failure to the distal parts like feet. Hence, there may be some gangrene formation of those parts, may lead to the death of the nails.  I advise you to consult a vascular surgeon for diagnosis and treatment. He may need to have color Doppler to see what parts are effected. Attending doctors are mostly concerned with the liver only, so they may not consider the feet.  Wishing for a quick and complete recovery. Thank you.
