Its burden is rising with aging population, and a substantial subset of patients meet practical criteria for middle meningeal artery embolization (MMAE). Contemporary understanding frames cSDH as a vascular-inflammatory disorder with recurrent microhemorrhage from fragile neovessels, largely supplied by branches of the middle meningeal artery. Standard care has traditionally relied on surgical evacuation, yet recurrence and reintervention remain frequent in high-risk cohorts. Over the last several years, randomized trials have evaluated MMAE as an adjunct or alternative to usual care. Three trials-EMBOLISE, STEM, and MEMBRANE-demonstrated reduced treatment failure or reoperation with adjunctive MMAE. These findings, coupled with rapid real-world adoption of MMAE, support embolization as an effective strategy to lower recurrence, especially when used with indicated surgery. Remaining questions include optimal patient selection, choice of embolic agent, target depth and laterality (distal vs. proximal, unilateral vs. bilateral), anesthesia strategy, and standardized angiographic workflows that mitigate anastomotic risks. Addressing these evidence gaps, along with health-system planning for rising volumes, will refine algorithms and improve outcomes in this growing population.</p>","PeriodicalId":48689,"journal":{"name":"Seminars in Interventional Radiology","volume":"42 6","pages":"655-665"},"PeriodicalIF":1.3,"publicationDate":"2026-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13038326/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147595517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Factors causing difficulty during thrombectomy include tortuous vasculature preventing access, challenging clot location (tandem or distal occlusions), underlying vessel abnormality, and hard-to-retrieve clots. Anticipating potentially challenging or refractory thrombectomy cases allows one to plan appropriate procedural strategies with the goal of maximizing technical success and favorable clinical outcome.
