What Researchers Did
Researchers conducted a retrospective study involving 211 patients with chronic subdural hematoma to identify risk factors for recurrence after middle meningeal artery embolization combined with burr hole drainage.
What They Found
Among the 211 patients included in the study, 35 (16.6%) experienced postoperative hematoma recurrence. The abstract did not provide the specific risk factors identified or the details of the predictive model established.
