Our goal is to demonstrate that middle meningeal artery (MMA) embolization combined with surgical evacuation can be a promising adjuvant option for treatment of cSDHs and prevent recurrence in symptomatic patients who require surgical treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>We retrospectively collected data from patients who underwent MMA embolization using polyvinyl alcohol particles and surgical evacuation with burr hole or craniotomy in a single center for the treatment of new and recurrent cSDHs. The primary outcome was recurrence of cSDH requiring surgical rescue during follow up, and secondary outcomes were defined as &gt;50% decrease in the maximum width of cSDHs on the longest follow-up computed tomography (CT) scan, complications following procedure, and improvement in modified Rankin scale (mRS) score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 51 patients successfully underwent 72 MMA embolization procedures (96% of the total 75 cases in the cohort) combined with surgical evacuation. Seventy cases (93.3%) achieved at least 50% reduction in the size of the cSDHs on the last CT imaging. A surgical evacuation was required in five cases (6.7%) due to cSDH recurrence during the follow-up period. There were three complications (6.0%) related to embolization procedure. Forty patients (78.4%) showed improvement in mRS score. There was one mortality (2%) regardless of the embolization and evacuation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our study demonstrates the safety and efficacy of adjunct MMA embolization in significantly reducing size and recurrence of cSDHs.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/15910199231196453","type":"journal-article","created":{"date-parts":[[2023,8,28]],"date-time":"2023-08-28T01:06:06Z","timestamp":1693184766000},"page":"162-169","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Middle meningeal artery embolization combined with surgical evacuation for chronic subdural hematoma: A single-center experience of 75 cases"],"prefix":"10.1177","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6481-3076","authenticated-orcid":false,"given":"Atakan","family":"Orscelik","sequence":"first","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6669-6616","authenticated-orcid":false,"given":"Yigit Can","family":"Senol","sequence":"additional","affiliation":[{"name":"Mayo Clinic"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6243-9495","authenticated-orcid":false,"given":"Cem","family":"Bilgin","sequence":"additional","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7446-624X","authenticated-orcid":false,"given":"Hassan","family":"Kobeissi","sequence":"additional","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Santhosh","family":"Arul","sequence":"additional","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harry","family":"Cloft","sequence":"additional","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Lanzino","sequence":"additional","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8495-0040","authenticated-orcid":false,"given":"David F","family":"Kallmes","sequence":"additional","affiliation":[{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Waleed","family":"Brinjikji","sequence":"additional","affiliation":[{"name":"Mayo Clinic"},{"name":"Mayo Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,8,27]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10143-004-0337-6"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/qjmed\/hcx143"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2017.0639"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.3171\/2014.9.JNS141550"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.3109\/02688699108998474"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.3340\/jkns.2010.48.6.518"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2003.98.6.1217"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2016.08.069"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199005000-00006"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.2176\/jns-nmc.2022-0164"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.4103\/ajns.AJNS_15_20"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1093\/neuros\/nyy521"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.4103\/ajns.AJNS_341_19"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.3171\/2020.10.JNS202856"},{"key":"e_1_3_2_16_2","doi-asserted-by":"crossref","unstructured":"Orscelik A Senol YC Bilgin C et al.
