Frontal Base Mixed Pial-Dural Arteriovenous Malformations: A Distinct Entity Requiring Differentiated Treatment From Anterior Cranial Fossa Dural Arteriovenous Fistulas.

ABSTRACT:

Background

Frontal base mixed pial-dural arteriovenous malformations (MPD-AVMs) are rare intracranial vascular malformations with both pial and dural components. Although they share some angioarchitectural similarities with anterior cranial fossa dural arteriovenous fistulas (ACF-DAVFs), the two represent different pathological processes, as ACF-DAVFs are supplied exclusively by dural arteries. This study provides an overview of frontal base MPD-AVMs, highlighting their differences from ACF-DAVFs, and discusses the therapeutic implications of their distinct angioarchitectural features.

Methods

This is a single-center case series study conducted between January 2018 and December 2024. The data of 11 patients who underwent endovascular treatment for frontal base MPD-AVMs and 2
