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 &#8220;subcallosal amnesic syndrome&#8221;.1,2 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.3 It is often difficult to identify this artery on images and its prior visualization could prevent significant sequalae in patients. Conclusion: The subcallosal artery is the most important perforating artery in the communicating artery, therefore its identification prior to treatment is essential4.]]></p></abstract>

Es fundamental su identificación previa a procedimientos endovasculares o quirúrgicos, ya que la lesión de esta arteria producirá un infarto bilateral de la región subcallosa y provocará un grave deterioro cognitivo y alteración de la memoria anterógrada, conocido como &#8220;síndrome amnésico subcalloso&#8221;.1 2 Presentamos el caso de un paciente con una malformación arteriovenosa peri callosa con identificación de la arteria subcallosa previa al tratamiento como única aferente.3 A menudo es difícil identificar esta arteria en las imágenes y su visualización previa podría prevenir secuelas importantes en los pacientes. Concluisión: la arteria subcallosa es la arteria perforante más importante de la arteria comunicante, por lo que su identificación previa al tratamiento es fundamental.4]]></p></abstract>
