This review evaluates the current evidence for the clinical management of congenital internal carotid artery hypoplasia (CICAH). We summarise clinical presentations diagnostic standards, imaging recommendations, treatment and follow-up. The review was prompted by a case of CICAH in a 50-year-old female who presented to our neurosurgery clinic with an acute episode of vertigo. The patient underwent CT angiogram, which showed an unusually low right carotid bifurcation. The right internal carotid artery (ICA) was hypoplastic, and the A1 segment of the anterior cerebral artery (ACA) was absent. Skull base CT showed an ipsilateral hypoplastic carotid canal. To summarise current evidence for clinical management of CICAH we followed PRISMA guidelines to identify papers meeting our predefined inclusion criteria. We searched three databases using the terms ‘ICA’ and ‘Hypoplasia’. We reviewed 41 papers meeting our criteria. 34 were clinical reports. We performed a data extraction and quality appraisal on these reports. We found that CICAH may be less rare than previously described. Blood pressure control in CICAH is crucial due to the increased risk of stroke and aneurysm formation. Follow-up imaging is strongly recommended. Carotid doppler sonography is a powerful and underutilised diagnostic tool, and carotid canal hypoplasia is not a pathognomic sign. In conclusion, clinicians should be alert to anatomic variations such as CICAH because these produce haemodynamic changes that may have serious clinical consequences. We recommend a central registry of patients with CICAH in order to understand the longer-term natural history of the condition.

Introduction and Importance: There are few cases of multiple simultaneous anterior communicating artery (AComA) aneurysms with A2 triplication and AComA duplication. Cases Presentation: 1- A fenestrated AComA with a saccular aneurysm (neck diameter 9 mm; dome height 8 mm) projecting superiorly from the distal AComA branch, as well as an anomalous artery arising from the posterior surface of the same AComA. 2- A duplicate AComA with a saccular aneurysm (neck diameter of 5 mm; dome height of 9 mm) projecting superioposteriorly from the distal AComA branch, as well as an anomalous artery arising from the anterior surface of the same AComA was diagnosed. Both were treated by microsurgical titanium clip occlusion. Clinical Discussion: Anatomical variations are believed to enhance the risk of anterior communicating artery (AComA) aneurysms, accounting for approximately 30% of all intracranial aneurysms. In such circumstances, the goal is to occlude the aneurysmal lesions safely while preserving the patency of other branches. Conclusion: AComA aneurysms accompanied by anomalous triplicated A2 and fenestrated AComA are rare and challenging. Such complex cases response best using microsurgery using titanium clip occlusion with durable favorable outcomes.
