RESUMEN
Objective To explore indications, ablated targets, efficacy and complications of microelectrode-guided thalamotomy and pallidotomy for treating Parkinson's disease(PD). Methods The clinical date of 225 PD patients underwent microelectrode guided thalamotomy and/or pallidotomg were retrospectively analyzed with UPDRS scores. Results The outcome of operation was excellent.The rate of improvement for tremor, rigidity, gait, balance and bradykinesia were 98 0%, 89 0%, 72 8%, 70 5% and 47 8% respectively. Postoperative motor UPDRS scores of both "on"/"off"states significantly decreased by 54 4% and 62 6% respectively. The frequency of post-operative complications was such as the following: bleeding caused by puncturing (0 48%),transient hiccup(6 7%), temporary dysarthria(5 5%), transient somnolence(10 0%) and mental disorder(4 5%). There were no severe and permanent complications. Conclusions The thalamotomy and/or pallidotomy guided by the microelectrode were the effective and safe method for treatment of PD, but the indications of this surgery should be well familiarize. The ablated target selection and its precise localization were of key importance for a better outcome.
