[Middle meningeal artery embolization for chronic subdural hematomas]

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Neurology

Background:

• Chronic subdural hematoma (cSDH) presents a significant clinical challenge with high recurrence rates.
• Current treatment options, primarily surgical, face limitations and high recurrence rates (2-37%).
• The unique pathophysiology of cSDH involves dural boundary cell injury, leading to a cycle of angiogenesis and bleeding within the hematoma membrane.

Purpose of the Study:

• To evaluate middle meningeal artery (MMA) embolization as a treatment for chronic subdural hematoma (cSDH).
• To assess the efficacy of MMA embolization as a standalone therapy or in conjunction with surgical intervention.
• To explore MMA embolization as an alternative to traditional surgical evacuation for cSDH.

Main Methods:

• The study focuses on the embolization of the middle meningeal artery (MMA), which supplies the cSDH membrane.
• This interventional radiology technique aims to induce hematoma resorption by occluding the neovascularized membrane.
• Data from studies using MMA embolization, both as sole therapy and combined with surgery, were reviewed.

Main Results:

• Middle meningeal artery (MMA) embolization demonstrates encouraging results in the treatment of chronic subdural hematoma (cSDH).
• Successful resorption of cSDH has been observed following MMA embolization.
• Long-term success rates of up to 90% have been reported for MMA embolization, either alone or combined with surgery.

Conclusions:

• Middle meningeal artery (MMA) embolization is a viable and effective treatment option for chronic subdural hematoma (cSDH).
• This endovascular approach offers a promising alternative to surgical treatment, potentially reducing recurrence rates.
• Further research and clinical application of MMA embolization are warranted for managing cSDH.
