Middle meningeal artery embolization to treat progressive epidural hematoma: a case report

Middle Meningeal Arterial Embolization Combined With Drilling in the Treatment of Acute Epidural Hematoma

OBJECTIVE

The purpose of this study was to determine the technical feasibility and safety of middle meningeal arterial (MMA) embolization combined with drilling drainage in the treatment of acute epidural hematoma (AEDH) by comparing it with traditional craniotomy in the treatment.

METHODS

One hundred seventeen patients with AEDH treated for MMA embolization combined with drilling and drainage or craniotomy hematoma removal from January 2017 to September 2020 were retrospectively analyzed and divided into a craniotomy group (n=85) and a minimally invasive group (n=32). Hematoma removal was performed in the craniotomy group, and MMA embolization combined with drilling and drainage was performed in the minimally invasive group. The general clinical data, imaging data, surgery, and follow-up of the 2 groups were compared and analyzed.

RESULTS

Compared with the craniotomy group, the residual hematoma volume in the minimally invasive group was higher than in the craniotomy group. The average postoperative drainage duration in the minimally invasive group was longer than in the craniotomy group. Compared with the craniotomy group, the minimally invasive group was associated with shorter operative time, less intraoperative bleeding, and lower rates of postoperative rebleeding. In addition, the incidence of postoperative complications and length of hospitalization in the minimally invasive group were significantly shortened.

CONCLUSION

Middle meningeal arterial embolization combined with drilling and drainage in the treatment of AEDH caused by MMA active bleeding is safe, effective, and more minimally invasive, and can be promoted and applied.

Case report: An overlooked complication of the dural suture after craniotomy: pseudoaneurysm of the middle meningeal artery with endovascular resolution

Aneurysms of the middle meningeal artery (MMA) are exceedingly uncommon and mainly result from traumatic brain damage, but this report describes a case of MMA aneurysm induced by cranial surgery. Surgery was performed on a 34-year-old male with cerebrovascular malformation and cerebral hemorrhage. Cerebral angiography revealed no MMA aneurysm before craniocerebral surgery; however, a postoperative angiogram revealed a new MMA aneurysm. Aneurysms of the MMA are uncommon consequences of brain surgery. Based on our findings, the MMA as well as other meningeal arteries should be avoided while suturing the dura mater tent to prevent aneurysms.

Recent Advances and Future Directions in Middle Meningeal Artery Embolization for Chronic Subdural Hematomas

PURPOSE OF REVIEW

The purpose of this review is to present a brief background on chronic subdural hematomas (cSDH), middle meningeal artery (MMA) embolization, and its role in decreasing recurrence of cSDH. A review of the most up-to-date literature should demonstrate the efficacy of this procedure.

RECENT FINDINGS

The latest data shows that MMA embolization is a safe procedure, with low complication rates and low recurrence rates. While cSDH managed with surgical evacuation can have a recurrence rate upwards of 30%, MMA embolization alone or as an adjunct to surgery decreases recurrence to less than 5% in most studies. MMA embolization can be especially useful in high-risk populations such as the elderly, patients on anti-platelet medication, and those with coagulopathies. It can also be done awake, done without general anesthesia, and is significantly less invasive than traditional surgical techniques. In reviewing the literature on MMA embolization, it is clear that there are numerous retrospective studies and systematic reviews demonstrating its safety and efficacy, and some prospective dual-arm studies that present novel information. The numerous clinical trials that are currently underway should help to further establish MMA embolization as standard of care in the management of cSDH.

Traumatic epidural hematoma treated with endovascular coil embolization

Background:

Traumatic cerebrovascular injury may result in epidural hematoma (EDH) from laceration of the middle meningeal artery (MMA), which is a potentially life-threatening emergency. Treatment ranges from surgical evacuation to conservative management based on a variety of clinical and imaging factors.

Case Description:

A 14-year-old male presented to our institution after falling from his bicycle with traumatic subarachnoid hemorrhage and a right frontotemporal EDH. The patient did not meet criteria for surgical evacuation and endovascular embolization of the right MMA was performed. Rapid resolution of the EDH was observed.

Conclusion:

This case corroborates the sparse existing literature for the potential role of endovascular embolization to treat acute EDH in carefully selected patients who do not meet or have borderline indications for surgical management.
