However, they all have high recurrence rates. Recently, embolization of the middle meningeal artery (MMA) following surgical evacuation of CSH has reduced the recurrence rate. We investigated the feasibility of combining the surgical obliteration of the MMA at the same time as the placement of a burr hole for evacuation of the CSH.\u0000\u0000\u0000\u0000We report on nine patients who underwent 11 of these combined procedure by the same surgeon in two hospitals, including clinical data and images during the perioperative and postoperative periods. Cardoso had previously reported details of the surgical technique. Two patients underwent bilateral procedures. Two patients had two burr holes because the hematomas did not extend caudally to the pterion, where the MMA enters the calvarium. Intraoperative fluoroscopy was used to locate the point of entry of the MMA into the calvarium in most cases, except in two instances when navigation was utilized.\u0000\u0000\u0000\u0000This small series of nine cases suggests the feasibility of using this combined procedure as an additional option to the treatment of CSHs, especially where endovascular treatment might not be readily available. Furthermore, it has the potential advantages of safety, efficacy, avoidance of a second endovascular procedure, faster disappearance of the subdural collection, lesser exposure to radiation, and cost containment. Larger prospective controlled series are needed to identify its potential usefulness.\u0000","PeriodicalId":504441,"journal":{"name":"Surgical Neurology International","volume":"54 33","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141799576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
