title: Somatosensory-evoked potentials after mesencephalic tractotomy for pain syndromes. Neuroradiologic and clinical correlations.
abstract: Eight patients affected by intractable pain underwent stereotactic mesencephalic tractotomy. Recordings of somatosensory-evoked potentials were made before and after the surgical procedure. Localization and size of the obtained lesion were controlled by computed tomography scans. Clinical result was compared with modification of postoperative somatosensory-evoked potentials and with the appearance of the lesion in the computed tomography scans.
