>E-MOVE reports from the 53rd Annual Meeting of the American Academy of

>1. S19.004 Surgical and device-related events with deep brain stimulation
>KE Lyons, WE Koller, SB Wilkinson, R Pahwa
>
>Surgical and device-related complications are very common following deep
>brain stimulation surgery, according to this report. Chart review was
>conducted on 206 consecutive patients (209 with essential tremor)
>receiving 275 DBS surgeries to the VIM (169 procedures), GPi (23
>procedures), or STN (83 procedures). Surgical complications included:
>--asymptomatic intracranial bleed (10% of procedures)
>--symptomatic intracranial bleed (2%)
>--seizures (3%)
>--headache (25%)
>--infection (6%).
>
>Device-related complications included:
>--lead replacements (9%)
>--lead repositionings (8%)
>--extension wire replacements (6%)
>--implantable pulse generator replacements (17%), approximately half of
>which were due to malfunction.
>
>
>2. P04.075 Bilateral subthalamotomy in Parkinson's disease
>L Alvarez, R Macias, MC Rodriguez-Oroz, et al.
>
>Eighteen PD patients received bilateral subthalamotomy with the aid of
>microelectrode recording. Improvement in UPDRS off motor score versus
>baseline was 62% at six months, and 58% at 16.7 months. At six months,
>levodopa dose was reduced by 60%, dyskinesias by 14%, and off-period
>dystonia by 47%. Adverse events included severe generalized chorea,
>dysarthria, and instability in 3 patients. Chorea resolved 1-6 months
>post-surgery, and dysarthria and instability after 6-12 months.
