My wife has had the same problem with collapsed veins due to repeated IV administration. She had to have a port installed in her chest with a catheter that runs directly to her heart. She gets weekly chemotherapy and blood tests. Hopefully your sister's veins will heal enough to not have to go this route. My wife had the port installed under local anesthetic in about two hours and the device has saved her countless hours of finding a good vein. Hope this advice was helpful.
