Some studies do not describe specific variants of the anterior communicating artery and group them as "fenestrations of the AComA", which limits the anatomical knowledge of this vessel (Kayembe et al, 1984; Dimmick & Faulder, 2009; Ferre et al, 2013; Hashemi et al, 2013; Iqbal, 2013; Kardile et al.
