The aim of the present study was to investigate the efficacy and safety of a \u201cradical\u201d surgical strategy in the treatment of PSM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The clinical histories, radiological findings, pathologic features, and surgical records of 53 patients with PSM admitted by the same surgical team using the \u201cradical\u201d surgical strategy were retrospectively analyzed between 2018 and 2023.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among the 53 PSM cases, 16 (30.2%) had a patent sinus proper, 28 (52.8%) had partial obstruction of the sinus proper, and 9 (17.0%) had complete obstruction of the sinus proper before the operation. During operation, Simpson grade I resection was performed in 34 (64.2%) cases and Simpson grade II in 19 (35.8%) cases. Postoperative pathologic examination suggested tumors of WHO grade I in 47 (88.7%) cases, WHO grade II in 4 (7.5%) cases, and WHO grade III in 2 (3.8%) cases. Postoperative complications primarily included a small amount of delayed intracerebral hemorrhage in 3 (5.7%) cases, exacerbation of cerebral edema in 3 (5.7%) cases, exacerbation of motor and sensory deficits in 4 (7.5%) cases, and intracranial infection in 2 (3.8%) cases. There were no cases of death or new-onset neurological dysfunction. Dizziness and headache symptoms improved to varying degrees, and a seizure-free status was achieved postoperatively. Excluding one case lost to follow-up, the average follow-up period was 33\u2009months, and there were no cases of recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>A \u201cradical\u201d strategy for the surgical management of PSM is effective, safe, and simple to perform, provided that the sagittal sinus is properly managed and its associated veins are protected.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fneur.2024.1364917","type":"journal-article","created":{"date-parts":[[2024,4,8]],"date-time":"2024-04-08T14:59:30Z","timestamp":1712588370000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Efficacy and safety of a \u201cradical\u201d surgical strategy in the treatment of parasagittal sinus meningioma"],"prefix":"10.3389","volume":"15","author":[{"given":"Zihao","family":"Duan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changlong","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoxiao","family":"Yan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Du","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohui","family":"Xia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Shi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hai","family":"Su","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yi","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuenong","family":"He","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qijiang","family":"Xiong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,4,8]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"175","DOI":"10.1001\/jama.1939.02800020081030","article-title":"Meningiomas: their classification, regional behaviour, life history, and surgical end results","volume":"112","author":"Cushing","year":"1939","journal-title":"JAMA"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"93","DOI":"10.1016\/B978-0-12-822198-3.00031-8","article-title":"Parasagittal meningiomas","volume":"170","author":"Mathiesen","year":"2020","journal-title":"Handb Clin Neurol"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"514","DOI":"10.3171\/jns.2006.105.4.514","article-title":"Results of attempted radical tumor removal and venous repair in 100 consecutive meningiomas involving the major dural sinuses","volume":"105","author":"Sindou","year":"2006","journal-title":"J Neurosurg"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"885","DOI":"10.1227\/NEU.0b013e3181ef2a18","article-title":"Perioperative and long-term outcomes from the management of parasagittal meningiomas invading the superior sagittal sinus","volume":"67","author":"Raza","year":"2010","journal-title":"Neurosurgery"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"46","DOI":"10.1016\/j.wneu.2013.07.119","article-title":"Meningiomas involving major dural sinuses: should we attempt at radical removal and venous repair?","volume":"81","author":"Sindou","year":"2014","journal-title":"World Neurosurg"},{"key":"ref6","first-page":"13508","article-title":"Guidance value of intracranial venous circulation evaluation to parasagittal meningioma operation","volume":"8","author":"Wang","year":"2015","journal-title":"Int J Clin Exp Med"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"8","DOI":"10.1054\/jocn.2001.0868","article-title":"Meningiomas invading the sagittal or transverse sinuses, resection with venous reconstruction","volume":"8","author":"Sindou","year":"2001","journal-title":"J Clin Neurosci"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"259","DOI":"10.1080\/01616412.2020.1847530","article-title":"Can safe and radical resection of all types of parasagittal meningiomas be achievable?
