Hello Richard. I read ur msg abt Mom and I wish u all the best of luck. I'm sure u will find this the place to get all the support u all need. My wife (pd patient) and I visit here every day to read the latest and we both ask you to keep us all informed EXACTLY with all the details, pre and post. As u hav read here there are both sides to this procedure and we know that with each operation more and more is put into the giant data bank of knowledge and experience. again best to u all Chuck and Joyce
