Chronic subdural hematomas (CSH) are one of the most frequent pathologies in emergency neurosurgical practice. Standard therapy for symptomatic CSH is surgical drainage. However, the recurrence rate after surgery is high (10 to 20% in the most of series, although it has been reported from 2 to 37%). Middle meningeal artery embolization (MMAE) is a promising minimally invasive procedure that has recently been proposed as an alternative or adjunctive treatment to surgery. The investigators hypothesize that early post operative endovascular treatment can reduce the recurrence rate in high-risk patients, improving neurological outcomes by reducing the need for reinterventions, hospitalizations, and post-operative complications. The aim of the investigators is to analyze the efficacy of and safety of early post-surgical embolization of MMA in reducing the risk of CSH recurrence.
