Hello everyone. My dad has been selected for a pallidotomy procedure at St Louis U. Have any of you had a pallidotomy completed at st louis U or by Dr Henderson- Whom I believe was taught by Dr Iacono. My dad and I would appreciate any input that those with experience can give us. Please post here as I have read from this list for about a year and find that I am impressed with the amount of help and hope that we give one another. I print much of the info i find here and send to my dad. or E mail me direct at [log in to unmask] Thanks, Bill Harper---- Son of Bill SR PDer
