Summary
Embolization of skull base tumors via the meningohypophyseal and inferolateral trunks is technically challenging but safe and effective. This approach can reduce blood loss and operative time, serving as a valuable surgical adjunct.
Area of Science:
- Neurosurgery
- Interventional Radiology
- Vascular Surgery
Background:
- Skull base tumors often receive blood supply from dural branches of the meningohypophyseal and inferolateral trunks.
- Embolization via these specific arteries is frequently avoided due to technical difficulties and risks.
- Successful embolization can significantly aid surgical treatment of these tumors.
Purpose of the Study:
- To review the outcomes, including success rates and complications, of tumor embolization performed through the meningohypophyseal and inferolateral trunks.
- To evaluate the safety and efficacy of this endovascular approach as a preoperative adjunct for skull base tumors.
Main Methods:
- Retrospective review of patients who underwent preoperative embolization between 2010 and 2020.
- Analysis of patient demographics, tumor characteristics, embolization details, and surgical outcomes (blood loss, transfusion needs, operative time).
Main Results:
- 14 patients underwent embolization via the meningohypophyseal (n=13) or inferolateral (n=4) trunks.
- An average of 79% of tumor volume was embolized.
- No mortality or morbidity was observed; average blood loss was 395 mL, no transfusions were needed, and average operative time was 7.3 hours.
Conclusions:
- Embolization through the meningohypophyseal and inferolateral trunks is feasible for select skull base tumors.
- This endovascular technique can be performed safely and effectively, offering benefits in surgical management.
