3T MAGNETIC RESONANCE-GUIDED FOCUSED ULTRASOUND THALAMOTOMY IN PATIENTS WITH ESSENTIAL TREMOR: THREE-YEAR CLINICAL EXPERIENCE FROM A SINGLE CENTER
- Stefano Tamburin (Italy)
Abstract
Background and Aims:
Magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy of the ventralis intermedius (Vim) nucleus is emerging as a minimally invasive treatment for patients with disabling and medication-refractory essential tremor (ET). We report our preliminary three-year experience on 52 patients with ET treated from January 2018 to December 2020 in a single center.
Methods:
From January 2018 to December 2020, 52 patients (31 men, 21 women, age: 73.5 ± 7.8 years) underwent MRgFUS thalamotomy of the Vim nucleus for disabling and refractory ET (tremor duration: 22.6 ± 12.1 years) with a 3T magnetic resonance scanner at Verona University Hospital.
Results:
At baseline the total Clinical Rating Scale for Tremor (CRST) score was 45.8 ± 15.6, and the Quality of Life in Essential Tremor Questionnaire (QUEST) score was 40.8 ± 13.8. At one-month follow-up, the total CRST score was 12.8 ± 6.3 and the QUEST score was 10.5 ± 4.1. Response persisted in the majority of patients at three-month, six-month, one-year, two-year and three-year follow-up. Side effects related to Vim nucleus thalamotomy included ataxia, speech disorder, ballism, paresthesia, and lower limb hypasthenia and were mild and transitory in most patients.
Conclusions:
Our data confirm that MRgFUS thalamotomy of the Vim nucleus is an effective and safe treatment for disabling and refractory ET and its effects are long-lasting.
