Maximizing safety in the treatment of a large choroidal fissure arteriovenous malformation: The essential role of anatomy, staged embolization, and microsurgical technique.

ABSTRACT:

Background

Arteriovenous malformations (AVMs) are complex congenital pathologies that require a deep understanding of their angioarchitecture and the involved brain anatomy. The ones within the temporal horn of the lateral ventricle present significant challenges for microsurgical treatment due to their deep location and proximity to critical neurovascular structures. These rare AVMs typically manifest with seizures or hemorrhage. They have afferents from the choroidal arteries, with arterial supply often arising from both the anterior and posterior circulations through the choroidal arteries, and exclusively deep venous drainage.

Case description

We report the case of a 44-year-old woman with a 1-year history of focal impaired awareness seizures accompanied by parosmia, hea
