[Surgical Technique of Ventral Intermediate Thalamic Deep Brain Stimulation].

ABSTRACT

Deep brain stimulation(DBS)of ventral intermediate(Vim)thalamic nucleus is an established procedure for tremor disorders, however, there are technical variations among specialists. The most common indications of Vim DBS are essential tremor(ET)and tremor dominant Parkinson's disease(PD), and less commonly other tremor disorders including Holmes tremor are treated with the same procedure. The variations of the surgical technique exist in the preoperative imagings and planning of the DBS electrode trajectory. In this review, we explain about the basic concept of Vim DBS and our surgical method.
