Traditionally, microvascular decompression of the facial nerve has been an effective treatment for posterior inferior and anterior inferior cerebellar artery as well as venous compression. The traditional technique involves Teflon felt or another construct to cushion the offending vessel from the facial nerve, or cautery and division of the offending vein. However, using this technique for severe vertebral artery (VA) compression can be ineffective and fraught with complications. The authors report the use of a new technique of VA pexy to the petrous or clival dura mater in patients with HFS attributed to a severely ectatic and tortuous VA, and detail the results in a series of patients.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>Six patients with HFS due to VA compression underwent a retrosigmoid craniotomy, combined with a far-lateral approach in some patients. On identification of the site of VA compression, the vessel was mobilized adequately for the decompression. Great care was taken to avoid kinking the perforating vessels arising from the VA. Two 8-0 nylon sutures were passed through to the wall of the VA and then through the clival or petrous dura, and then tied to alleviate compression on cranial nerve VII.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Patients were followed for at least 1 year postoperatively (mean 2.7 years, range 1\u20134 years). All 6 patients had complete resolution of their HFS. Facial function was tested postoperatively, and was stable when compared with the preoperative baseline. Two of the 3 patients with preoperative tinnitus had resolution of this symptom after the procedure. Postoperative imaging demonstrated VA decompression of the facial nerve and no evidence of stroke in all patients. One patient suffered from hearing loss, another developed a postoperative transient unilateral vocal cord paralysis, and a third patient developed a pseudomeningocele that resolved with the placement of a lumbar drain.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Hemifacial spasm and other neurovascular syndromes are effectively treated by repositioning the compressing artery. Careful study of the preoperative MR images may identify a select group of patients with HFS due to an ectatic VA. Rather than traditional decompression with only pledget placement, these patients may benefit from a VA pexy to provide an effective, safe, and durable resolution of their symptoms while minimizing surgical complications.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2010.12.jns10891","type":"journal-article","created":{"date-parts":[[2011,1,28]],"date-time":"2011-01-28T15:10:13Z","timestamp":1296227413000},"page":"1800-1804","source":"Crossref","is-referenced-by-count":38,"title":["Vertebral artery pexy for microvascular decompression of the facial nerve in the treatment of hemifacial spasm"],"prefix":"10.3171","volume":"114","author":[{"given":"Manuel","family":"Ferreira","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian P.","family":"Walcott","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian V.","family":"Nahed","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Massachusetts General Hospital and Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laligam N.","family":"Sekhar","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns10891","series-title":"J Neurosurg","first-page":"929","article-title":"Use of fenestrated aneurysm clips in microvascular decompression surgery.
