The OTEMACS study is a prospective, multicenter clinical trial with randomized treatment allocation, open label treatment and blinded endpoint evaluation (PROBE), designed to demonstrate that MMA embolization via a minimally invasive endovascular approach combined with standard (surgical/conservative) management is superior to standard management alone, in reducing the rate of CSDH-related surgical interventions and the recurrence rate in patient with CSDH at 90 days. Eligible symptomatic CSDH patients will be randomly assigned, in a 1:1 ratio, to receive either surgical treatment plus an adjuvant MMA embolization (ST+MMAE group; the Experimental arm) or surgical treatment alone (ST group; the Control arm). Eligible symptomatic nonsurgically treated patients with CSDH will be randomized, in a 1:1 ratio, to MMA embolization (MMAE group; the Experimental arm) or conservative management (CM group; the Control arm).
