Abstract

INTRODUCTION
The subcallosal artery is the longest perforating artery of the anterior communicating artery (AcoA). Despite its great importance and being present in 50-79% of the specimens, it is little described in the literature. It is essential to identify prior to endovascular or surgical procedures, because the lesion of this artery will produce a bilateral infarction of the subcallosal region and causing a severe cognitive impairment and alteration of anterograde memory, known as “Subcallosal amnesic syndrome”.
We present the case of a patient with a peri callosal arteriovenous malformation with identification of the Subcallosal artery prior to treatment as the only afferent. It is often difficult to identify this artery on images and its prior visualization could prevent significant sequalae in patients. We concluded that the Subcallosal artery is the most important perforating artery in the communicating artery, therefore its identification prior to treatment is essential.
