Treatment of advanced Parkinson's disease by subthalamotomy: One-year results
We studied effects on parkinsonian features at 6 and 12 months in 12 patients who underwent unilateral ablation of subthalamic nucleus (STN). Microelectrode mapping was used, and a lesion was created in the STN using thermal coagulation and confirmed with magnetic resonance imaging. At 6 months post...

Summary: | We studied effects on parkinsonian features at 6 and 12 months in 12 patients who underwent unilateral ablation of subthalamic nucleus (STN). Microelectrode mapping was used, and a lesion was created in the STN using thermal coagulation and confirmed with magnetic resonance imaging. At 6 months postoperatively, improvements were seen in several areas: 1) Unified Parkinson's Disease Rating Scales II and III (UPDRS II and III) scores, 30% in off period, 38% in on period; 2) Schwab and England Scale (S&E) score, 21%; and 3) on dyskinesia, 85%. Contralateral rigidity, bradykinesia, UPDRS II and III scores, and S&E scores remained improved at 12 months. Daily dosage of levodopa requirement was reduced by 42%. Axial motor features, gait, postural stability, off period tremor, and motor fluctuation improved at 6 and 12 months but showed a decline in benefits at 18 months. Complications include 3 cases of hemiballism, of whom 2 patients recovered spontaneously but 1 died from aspiration pneumonia. One patient had asymptomatic hematoma, and 2 suffered transient postural asymmetries. We conclude that unilateral subthalamotomy results in moderate improvement in all aspects of parkinsonian features, allows reduction in the dose of levodopa required, and ameliorates drug‐induced complications throughout 12‐month assessments. © 2003 Movement Disorder Society |
