My dad had surgery a week ago to remove scar tissue from previous surgeries. It was supposed to be a simple outpatient procedure and he was to be able to go home the same day. During the procedure the docter cut a vital vein in his leg by mistake and caused him to lose a few pints of blood. He could have died, was it not for a surgeon that happened to be there to close the vein. My dad has been in the hospital for a week now and his leg will be swollen for a year and he will have to use a walker until new veins grow to replace the one he lost. He is in a lot of pain and has suffered a great deal. Needless to say, what he went in to get done was not done. My question is, what is required in order to present a strong case against the hospital for pain and suffering and possible malpractice? My parents have been through a lot, as my father has just finished an 11 month treatment of chemotherapy right before this happened. Any advice or information would be greatly appreciated.
