Efficacy and safety of middle meningeal artery embolization in the management of refractory or chronic subdural hematomas: a systematic review and meta-analysis

Middle Meningeal Artery Embolization in Chronic Subdural Hematoma: Implications of Pathophysiology in Trial Design

“…In other more recent systematic reviews, the failure for cSDH patients undergoing MMA embolization was 4.1 and 2.4% for primary and recurrent cases, respectively (28). The need for surgical rescue in patient undergoing MMA embolization was 2.7% (29). MMA embolization had a 26 and 20% risk reduction for cSDH recurrence and surgical intervention, respectively (29).…”

“…The need for surgical rescue in patient undergoing MMA embolization was 2.7% (29). MMA embolization had a 26 and 20% risk reduction for cSDH recurrence and surgical intervention, respectively (29). The rate of complications for MMA embolization was 1.2% (29).…”

“…MMA embolization had a 26 and 20% risk reduction for cSDH recurrence and surgical intervention, respectively (29). The rate of complications for MMA embolization was 1.2% (29). Given those promising results, a randomized clinical trial (ChiCTR1800018714), three parallel assignment open label studies (NCT04065113, NCT04095819, NCT04270955) and a single arm open label study (NCT03307395) are recruiting patients to further study MMA embolization in cSDH.…”

Remote-Proctoring bei neuroradiologischen Interventionen

“…Die Indikationen für neuroendovaskuläre Techniken werden möglicherweise zukünftig weitere Krankheitsbilder umfassen. So wird derzeit die Wirksamkeit der Behandlung des chronischen subduralen Hämatoms (cSDH) mittels Embolisation der meningealen Arterien [5][6][7] und die Behandlung symptomatischer nichtstenotischer Plaques der A. carotis interna [8,9] untersucht.…”

Outpatient management of chronic expanding subdural hematomas with endovascular embolization to minimize inpatient admissions during the COVID-19 viral pandemic

“…In our practice (and in other centers around the country) we have increasingly used embolization of the middle meningeal artery (MMA) as the sole treatment for chronic expanding SDHs. [6][7][8][9][10][11][12][13] The premise is based on the observation that the outer membrane of a chronic SDH parasitizes its blood supply from the MMA. Subsequently, embolization of this artery reduces the rate of flow through this fragile and porous vascular network and prevents further microhemorrhage and transudation of blood and fluid into the subdural space.…”
