A ruptured anterior cerebral artery (ACA) aneurysm is reported in a patient in whom an anomalous ACA arose from the internal carotid artery at the bifurcation. The aberrant artery coursed anteriorly along the ipsilateral olfactory tract and made a hairpin turn posterior to the olfactory bulb, supplying the circulation of the ACA. Persistence of the primitive olfactory artery is suggested as an embryological origin of this vascular anomaly.
据报道，一名患者的大脑前动脉（ACA）动脉瘤破裂，该患者的异常大脑前动脉起源于颈内动脉分叉处。这条异常动脉沿同侧嗅束向前走行，在嗅球后方呈发夹样转弯，为大脑前动脉的循环供血。原始嗅动脉持续存在被认为是这种血管异常的胚胎学起源。
