title: [Microelectrode-guided posteroventral pallidotomy for Parkinson's disease: clinical study of 100 cases].
abstract: OBJECTIVE
  To evaluate the outcome of posteroventral pallidotomy (PVP) for Parkinson's disease (PD).
  
  
  METHODS
  The data from 100 patients with PD receiving PVP were retrospectively analyzed with UPDRS.
  
  
  RESULTS
  PVP significantly improved PD symptoms. Several typical symptoms were improved:tremor in 72% patients, rigidity 81%, akinesia 71%, gait 60%, balance 64% and off state 75%.
  
  
  CONCLUSIONS
  PVP improves Parkinsonian symptoms, and is superior to classical thalamotomy. Microelectrode recording is essential to surgical results and avoidance of severe complication.
