No Significant Advantage of middle meningeal artery Embolization Over Standard Care in Preventing CSDH Recurrence: JAMA
A new study published in the Journal of American Medical Association showed that middle meningeal artery (MMA) embolization did not significantly reduce recurrence rates of chronic subdural hematoma (CSDH) at 6 months compared to standard medical care. However, the effect size aligns with previous studies suggesting potential benefits, indicating a need for further research into this treatment approach.
One possible therapy for chronic subdural hematoma is middle meningeal artery embolization. Thus, to determine if MMA embolization is more effective than standard treatment in lowering the chance of CSDH recurrence at 6 months in patients who had surgery and were at high risk of recurrence, this research was carried out.
This clinical study from July 2020 to March 2023, was at 12 French neurosurgical or comprehensive neurosurgical and interventional neuroradiology institutions recruited patients who had surgery for CSDH recurrence or a first CSDH episode at high risk of recurrence. Within 7 days following surgery, the participants were randomly assigned to receive either normal medical treatment alone (171 patients, control group) or MMA embolization with microparticles (171 patients, intervention group).
