Abstract:
Objective:To probe the role of CT in guided thalamotomy and posteroventral pallidotomy for Parknson's disease.Methods:With the help of microelectrode guided technique,ipsilateral thalamotomy and pallidotomy were used for 150 Parkinsonian disease.To fix position with CT in operation,the three dimension for target was measured.Results:80 percent of targets orientated by CT tallyed with that recorded by microelectrode electrophysiology.The error of the rest 20% was less than 2 mm on the average.Conclusions:By CT the targets can be accurately located in 3 dimension during operation.The cost of this kind of orientation is 50 percent less than that of SPCT or MRI.
