The intraoperative microrecording in the nucleus ventralis intermedius (VIM) of the left thalamus revealed tremor-synchronous grouped discharges with a vigorous (2.7 Hz) action tremor predominantly in the shoulder and upper arm. High frequency electrical stimulation in the VIM did not affect the tremor. A posteroventral pallidotomy (PVP) was performed and resulted in the successful alleviation of all tremor activity. Posteroventral pallidotomy is known to alleviate parkinsonian tremors, especially those occurring in the contralateral lower extremity, trunk, and proximal segment of the contralateral upper extremity. The authors consider the pallidoreticular pathway to be an important tremor-mediating pathway for the proximal segment of the upper extremities and believe it can be controlled more effectively by PVP than by VIM thalamotomy, as demonstrated by the PVP-induced resolution of the midbrain tremor observed in this case.<\/jats:p>","DOI":"10.3171\/jns.1999.91.5.0885","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:20:08Z","timestamp":1242235208000},"page":"885-888","source":"Crossref","is-referenced-by-count":38,"title":["Posteroventral pallidotomy for midbrain tremor after a pontine hemorrhage"],"prefix":"10.3171","volume":"91","author":[{"given":"Yasushi","family":"Miyagi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumio","family":"Shima","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsuya","family":"Ishido","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masashi","family":"Moriguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazufumi","family":"Kamikaseda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"103","DOI":"10.1212\/WNL.39.1.103","article-title":"Post-traumatic tremor.","volume":"39","author":"Biary","year":"1989"},{"key":"b2","series-title":"Brain","doi-asserted-by":"publisher","first-page":"1001","DOI":"10.1093\/brain\/106.4.1001","article-title":"The correlation between tremor characteristics and the predicted volume of effective lesions in stereotaxic nucleus ventralis-intermedius thalamotomy.","volume":"106","author":"Hirai","year":"1983"},{"key":"b3","series-title":"Brain","doi-asserted-by":"publisher","first-page":"327","DOI":"10.1093\/brain\/27.3.327","article-title":"On certain tremors in organic cerebral lesions.","volume":"27","author":"Holmes","year":"1904"},{"key":"b4","series-title":"J Image Guided Surg","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1002\/(SICI)1522-712X(1995)1:3<133::AID-IGS2>3.0.CO;2-B","article-title":"Combined stereotactic thalamotomy and posteroventral pallidotomy for Parkinson's disease.","volume":"1","author":"Iacono","year":"1995"},{"key":"b5","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1118","DOI":"10.1227\/00006123-199506000-00008","article-title":"The results, indications, and physiology of posteroventral pallidotomy for patients with Parkinson's disease.","volume":"36","author":"Iacono","year":"1995"},{"key":"b6","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"314","DOI":"10.3171\/jns.1998.89.2.0314","article-title":"Stereotactically guided thalamotomy for treatment of parkinsonian tremor isolated to the lower extremity.
