Surgical fenestration is the primary treatment and has shown generally favorable outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>\n                      This retrospective case series includes 18 patients who underwent SAW fenestration at a tertiary care center between 2015 and 2024. The mean age was 54.7 years, and the mean BMI was 34.0 kg\/m\n                      <jats:sup>2<\/jats:sup>\n                      . Preoperative symptoms included back pain (n = 15), sensory changes (n = 15), gait instability (n = 14), and lower extremity weakness (n = 14). Most patients experienced symptom improvement postoperatively, although 5 (27.8%) reported worsening in at least one domain. Of the 15 patients with a preoperative scalpel sign, 46.7% showed radiographic resolution following surgery.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>The authors present one of the largest single-center series of surgically treated SAW to date. While a subset of patients experienced persistent or worsened symptoms, the majority demonstrated both clinical and radiological improvement. These findings support surgical fenestration as a generally effective intervention for symptomatic SAW. Given the progressive nature of the condition and its potential impact on function, early recognition and surgical referral are critical to optimize patient outcomes.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE25910\">https:\/\/thejns.org\/doi\/10.3171\/CASE25910<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case25910","type":"journal-article","created":{"date-parts":[[2026,4,13]],"date-time":"2026-04-13T15:26:36Z","timestamp":1776093996000},"source":"Crossref","is-referenced-by-count":1,"title":["Clinical outcomes of resection of thoracic arachnoid webs: patient series"],"prefix":"10.3171","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4310-1158","authenticated-orcid":true,"given":"Nathan P.","family":"Ritchey","sequence":"first","affiliation":[{"name":"College of Medicine, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6970-2345","authenticated-orcid":true,"given":"Connor C.","family":"Jacob","sequence":"additional","affiliation":[{"name":"College of Medicine, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3464-5697","authenticated-orcid":true,"given":"Joshua","family":"Weinberg","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan G.","family":"Eaton","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1052-664X","authenticated-orcid":true,"given":"Bryan","family":"Ladd","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanus","family":"Viljoen","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siri Sahib S.","family":"Khalsa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Grossbach","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The Ohio State University, Columbus, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"2","key":"bib1","series-title":"J Neurosurg Spine","first-page":"287","article-title":"Dorsal arachnoid web with spinal cord compression: variant of an arachnoid cyst?
