Tratamiento del Temblor Esencial mediante Talamotomía Estereotáxica.

Essential tremor is characterized by its low frequency, mainly affecting upper extremities and less frequently lower limbs and head. The origin of this disease is not well known, but it has been described in familiar forms as an autosomic dominant hereditary transmission pattern. We report three patients with essential tremor refractory to pharmacotherapy who underwent stereotactic thalamotomy of the ventrolateral nucleus. In all cases the procedure was unilateral. In two patients, the tremor completely remitted and in one patient the tremor decreased more than 50%. Tremor was defined by the Unified Parkinson’s scale. There were no complications related to surgery. We conclude that stereotactic ventrolateral nucleus thalamotomy can be of benefit in patients with essential tremor due to its low morbidity in selected patients.
