Abstract
Understanding tumor attachments and management of feeding arteries are very important factors to achieve safe resection of skull base meningioma. We examined the distributions and frequencies of feeding arteries in skull base meningioma by cerebral angiography, and also assessed relationships to tumor attachment for skull base meningioma. We enrolled patients with skull base meningioma who underwent MRI and cerebral digital subtraction angiography (DSA), from September 2015 to October 2022. Subjects comprised 115 patients (32 males, 83 females; mean age, 52.7 years) with 117 meningiomas showing tumor attachments around the “cavernous sinus to upper part of the clivus” (Area 1), “lower part of the clivus to foramen magnum” (Area 2), and “tentorium around the petrous bone” (Area 3). We examined feeding arteries based on cerebral angiography and counted the number of related feeding arteries. Particularly frequent arteries, such as the dorsal meningeal artery (DMA), ascending pharyngeal artery (APA), tentorial artery (TA), and petrosal branch (PB) of the middle meningeal artery (MMA) were analyzed for associations of tumor attachment to Areas 1–3. DMA, APA, TA, and PB are very frequent feeding arteries among skull base meningiomas. In some cases, the artery of the foramen rotundum, posterior ethmoidal artery, recurrent meningeal artery, posterior meningeal artery, etc., supply blood to the skull base meningioma. Meningiomas with DMA as a feeding artery correlated strongly with tumor attachment to Area 1 (p<0.001). Meningiomas with APA correlated strongly with tumor attachment to Area 2 (p<0.001). Meningiomas with TA correlated strongly with tumor attachment to Area 3 (p<0.001). PB correlated with Area 3 (p<0.05). Visualization of these arteries suggests tumor attachments to the correlated areas. An accurate anatomical understanding of tumor attachment and feeding arteries is essential to determine appropriate surgical strategies for skull base meningioma. Pre-operative DSA can provide further understanding of the feeding arteries and attachments of skull base meningioma.
