Multichannel fenestration of the internal carotid artery (ICA) is a rare, previously unreported developmental anomaly with unknown clinical significance. Although previously thought to have distinct embryologic origins, the presence of multiple channels in a short-segment fenestration favors a common developmental pathway for the origin of duplications and fenestrations: the persistence of a plexiform vascular network from the 4-mm to 5-mm embryologic stage of development.
颈内动脉（ICA）多通道开窗是一种罕见的、此前未报道过的发育异常，其临床意义尚不清楚。尽管此前认为其有不同的胚胎学起源，但短节段开窗中多个通道的存在支持重复和开窗起源的共同发育途径：在胚胎发育的4毫米至5毫米阶段，丛状血管网络持续存在。
