Efficacy and Outcome of Embolization of Intracranial Meningiomas With Minimal Resources

BACKGROUND

Preoperative embolization of intracranial meningiomas is an accepted treatment modality and offers many advantages for subsequent surgery. It has also been used as a primary therapy without subsequent surgery in selected cases. In this study, the authors share their experience of this procedure with minimal resources carried out in cases where definitive surgery was not advisable.

METHODS

This is a prospective study of 6 cases of meningiomas treated over a period of 11 months (November 2020 to September 2021). None of the cases were fit for prolonged surgery under general anesthesia and also had certain comorbid conditions. Embolization was done in a setup with limited resources without a fully equipped catheterization lab. Post-procedure magnetic resonance imaging (MRI) was done within 48 hours of the procedure. Follow-up was done in the outpatient department.

RESULTS

There was complete disappearance of tumor blush in all the 6 cases. Immediate post-procedure MRI revealed significant necrosis of the tumor cavity. Three cases succumbed to their primary comorbid conditions and in the other cases follow-up was uneventful. Following embolization, clinical improvement of presenting symptoms was seen in all 6 cases.

CONCLUSIONS

In resource-restricted settings, by introducing such innovative methods it is possible to perform selected endovascular procedures. Embolization can be used as a primary treatment modality avoiding subsequent surgery in selected cases with a good outcome.
