Summary
Embolization of skull base meningiomas from internal carotid artery (ICA) feeders can cause fever and elevated C-reactive protein (CRP). Increased CRP may indicate successful embolization, despite potential collateral pathways.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Oncology
Background:
- Skull base meningiomas often receive blood supply from meningeal arteries.
- Embolization is a common preoperative treatment for these tumors.
- Internal carotid artery (ICA) meningeal branches can be significant tumor feeders.
Purpose of the Study:
- To report pitfalls and evaluation methods for embolization of skull base meningiomas.
- To investigate the relationship between embolization of ICA meningeal feeders and post-procedural outcomes.
- To assess the significance of C-reactive protein (CRP) levels after embolization.
Main Methods:
- Retrospective analysis of 15 skull base meningioma cases treated with embolization.
- Focus on tumors supplied by meningeal branches of the ICA.
- Evaluation included post-embolization MRI and serum CRP levels.
Main Results:
- ICA meningeal branches were dominant feeders in 10 of 15 patients.
- Successful embolization from ICA meningeal branches was achieved in 10 patients.
- Eight of these 10 patients developed fever and elevated CRP post-embolization.
- Collateral pathways between ICA and external carotid artery systems were identified during procedures.
Conclusions:
- Embolization of skull base meningiomas via ICA meningeal arteries can lead to post-procedural fever and elevated CRP.
- Elevated CRP may serve as an indicator of effective embolization.
- Awareness of collateral pathways is crucial during embolization procedures.
