Studies have additionally shown a posterior fossa or deep AVM location to portend a more aggressive natural history. The authors reviewed the literature on posterior fossa AVMs, finding their annual rupture rates to be as high as 11.6%, an important factor that underscores the importance of aggressive treatment of lesions amenable to intervention as therapeutic options and results continue to improve.<\/jats:p>","DOI":"10.3171\/2009.2.focus0914","type":"journal-article","created":{"date-parts":[[2009,5,1]],"date-time":"2009-05-01T09:57:26Z","timestamp":1241171846000},"page":"E12","source":"Crossref","is-referenced-by-count":106,"title":["Posterior fossa arteriovenous malformations"],"prefix":"10.3171","volume":"26","author":[{"given":"Omar M.","family":"Arnaout","sequence":"first","affiliation":[{"name":"Department of Neurological Surgery, The Feinberg School of Medicine and McGaw Medical Center, Northwestern University, Chicago, Illinois; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley A.","family":"Gross","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S.","family":"Eddleman","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, The Feinberg School of Medicine and McGaw Medical Center, Northwestern University, Chicago, Illinois; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernard R.","family":"Bendok","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, The Feinberg School of Medicine and McGaw Medical Center, Northwestern University, Chicago, Illinois; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher C.","family":"Getch","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, The Feinberg School of Medicine and McGaw Medical Center, Northwestern University, Chicago, Illinois; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
