  • Direct identification of ventrointermediate nucleus of the thalamus on magnetic resonance and computed tomography images
    Surgical Neurology, 1999
    Co-Authors: Arun Angelo Patil, Thomas Falloon, Francis J. Hahn, Jason J. Cheng, Stephanie Wang
    Abstract:

    Abstract OBJECTIVE The ventro-intermediate (Vim) nucleus of the thalamus is a commonly used target for the treatment of tremor. The Thalamic Fasciculus contains myelinated fibers, believed to play a role in the generation of tremor, that converge into a dense bundle at the inferior aspect of the Vim nucleus, making it visible on magnetic resonance (MR) and computed tomography (CT) images. This structure, therefore, can be visualized directly and targeted for thalamotomy. METHODS Thalamotomies were performed on nine patients (who have a follow-up of 13–23 months) with parkinsonian and essential tremors using MR and CT images. The tremor target was hypointense on MR images obtained in inversion recovery sequence and hypointense on CT images. It was therefore visualized, directly targeted, and probed. Stimulation studies were done to physiologically confirm accuracy of the probe placement and then a radiofrequency lesion was made. RESULTS Stimulation of the target identified as the Vim nucleus on MR and CT images produced responses similar to those expected from the Vim nucleus. After this site was lesioned tremor disappeared in all nine patients. CONCLUSION The Vim nucleus of the thalamus is visible on MR and CT images. Destruction of this target abolishes parkinsonian and essential tremors.

  • Anatomy of the subThalamic nucleus, with correlation of deep brain stimulation [RETRACTED].
    Journal of Neurosurgery, 2015
    Co-Authors: Akın Akakın, Baran Yılmaz, Turker Kilic, Albert L. Rhoton
    Abstract:

    OBJECT The goal in this study was to examine the cadaveric anatomy of the subThalamic nucleus (STN) and to analyze the implications of the findings for deep brain stimulation (DBS) surgery. METHODS Five formalin-fixed human cerebrums were dissected using the Klingler fiber dissection technique. Digital photographs of the dissections were fused to obtain an anaglyphic image. RESULTS The STN was located posteroinferior to the anterior corticospinal fibers, posterosuperior to the substantia nigra, and anteromedial to the red nucleus, lenticular Fasciculus, and Thalamic Fasciculus. The subThalamic region is ventral to the thalamus, medial to the internal capsule, and lateral and caudal to the hypothalamus. The nuclei found within the subThalamic region include the STN. The relationship between the STN and surrounding structures, which are not delineated sharply, is described. CONCLUSIONS The fiber dissection technique supports the presence of the subThalamic region as an integrative network in humans and offe...
