Relationship of the P angle with stereotactic Arc in intraoperative outcome of patients with Parkinson's disease undergoing deep brains stimulation

ABSTRACT

Background and Aim: DBS [deep brain stimulation] is a new and successful technique in treatment of symptoms of Parkinsonism especially after drug resistance. Research in this field is mostly designed for evolution of this technique. The present study aimed at evaluating the relationship between the angle formed in midsagittal and STN [sub-thalamic nucleus] axis line and recording length in the final electrode p lacement
