Methods Guided by computed tomography and magnetic resonance imaging image mergence, we transplanted 4 × 106 hRPE cells into the putamina and lateral ventricles of 17 PD cases by stereotactic surgery. The transplantation site was located in the contralateral side of the symptoms and signs. Results At 3 months after operation, the effective rates of cell transplantation were 82.4% in the contralateral site and 64.7% in the ipsilateral site. Minority of the cases had mild dizziness and hemiparesis, but the durations were short. Conclusions Computer-assisted stereotactic transplantation of hRPE for the treatment of PD is safe and efficient. From the Department of Neurology, Yishui Central Hospital, Shandong, China.
