AIm: Knowledge of cerebrovascular morphology is integral in planning neuroendovascular interventions, especially for procedures involving placement of stents, flow diverters or stentrievers. There is insufficient data on angiographic normative values of cerebral circulation in the pediatric age group since angiograms are uncommonly performed in children except for arteriovenous malformations in which arterial dimensions are larger than normal. We aimed to measure the diameters of internal carotid circulation (ICC) arteries on digital subtraction angiograms of pediatric patients and determine the growth trends. mATeRIAL and meTHods: This is a retrospective cross-sectional study measurements of ICC arteries of 64 pediatric patients (4 -122 months) with retinoblastoma undergoing intra-arterial chemotherapy.ResuLTs: Petrous, cavernous, supraclinoid and choroidal segments of internal carotid artery (ICA) and anterior cerebral artery (ACA) diameters had significant correlation with age. Most of the growth was noted in the first 36-48 months of life. Middle cerebral artery (MCA) diameter did not show significant correlation with age. 87% of the adult diameter of the MCA was attained in the first 6 months of life. ICC arteries reached 81% to 99% of adult sizes in the first 48 months of life. On the contrary, the main iliac artery was only 59% of the adult diameter at this age group.CoNCLusIoN: Use of current intracranial stents in children appears tolerable due to the growth pattern of ICC arteries. Based on this data, the current armamentarium of intracranial stents or stent-like devices is sufficient to cover the need in the pediatric population.KeywoRds: Cerebral arteries, Internal carotid artery, Diameter, Endovascular treatment, Stent, Flow diverter, Morphometry ÖZ AmAÇ: Nöroendovasküler girişimlerde, özellikle de stent, akım yönlendirici ve benzeri cihazlar kullanıldığında, serebrovasküler morfolojinin bilinmesi önemlidir. Serebral anjiyografi, arteryel boyutların normalden daha büyük olduğu arteriovenöz malformasyonlar dışında çocuklarda sık olarak yapılmadığından, pediatrik yaş gurubunda serebral dolaşımın anjiyografik normotif değerleri hakkında yeterli bilgi bulunmamaktadır. Çocuk hastalarda internal karotid dolaşımı (İKD) arterlerinin çaplarını ölçüp büyüme eğilimlerini belirlemeyi amaçladık. yÖNTem ve GeReÇLeR: Çalışmamız, retinoblastom için intraarteryel kemoterapi yapılan 64 çocuk hastada (yaş: 4 -122 ay) İKD arterlerinin ölçüldüğü retrospektif kesitsel bir çalışmadır.BuLGuLAR: İnternal karotid arterin petröz, kavernöz, supraklinoid ve koroidal segmentleriyle anterior serebral arter (ASA) çapları yaş ile anlamlı korelasyon göstermekteydi. Damarsal büyümenin 36-48 ayda tamamlanmaya yaklaştığı saptandı. Orta serebral arter (OSA) çapı yaş ile anlamlı korelasyon göstermedi. Bu arterde ilk 6 ayda arteryel çapın %87'sine ulaşıldığı izlendi. İKD arterlerinin 48 ay itibarıyla erişkin boylarının % 81-99'una ulaştığı görüldü. Bunun aksine ana iliak arter bu yaş gurubunda erişkin çapının sadece % 59'uydu. soN...

“…[10][11][12][13][14][15][16][17][18][19][20] Kasuya et al 13 used 3-D CT angiography to study anterior communicating artery complexes and found that aneurysms were associated with increased angles between the directions of flow in the A1 and A2 segments. Similarly, Ingebrigtsen et al 14 found aneurysms to be associated with larger branch angles.…”

“…Previous case series have demonstrated that morphological factors of surrounding vasculature are correlated with aneurysms formation. [10][11][12][13][14][15][16][17][18][19][20] However, the contribution of vessel morphology at the basilar apex to the risk of aneurysm formation is unique and has not been described before. To control for genetic and environmental contributions, we examined the basilar apex in patients with at least 1 aneurysm and compared those with or without a BTA.…”

“…Although the MCA has been the subject of extensive anatomical studies for the last 200 years, it still remains incompletely described. Only a limited number of reports have addressed the features of its morphometry such as diameter and length (Tanriover et al, 2003; Kim and Kang, 2007). There are only few studies that have included the internal diameter of the MCA based on computed tomography (CT) or magnetic resonance (MR) angiography.…”

With an increase in the understanding of the formation and treatment of cerebral aneurysms and an improvement in imaging technology, actual standardized measurement values for the cerebral arteries are necessary. Therefore, the aim of this study was to provide a detailed assessment of the three-dimension (3D) morphology (vessel's curvature and trajectory) and 3D-morphometry of the M1 segment of the middle cerebral artery using computer tomography angiography (CTA) images. The DICOM files from CTA of 40 male and 75 female individuals with a mean age of 50.1 years were analyzed using an interactive postprocessing 3D volume-rendering algorithm. Specifically, the M1 segment was evaluated. Calculations included the length, internal diameter, volume, deviation (DI) and tortuosity indices (TI). The M1 segment had a mean internal diameter of 2.23 mm and was greater in men. M1 asymmetry was identified in 23.4% of the individuals and was more common in women. The mean length was 15.62 mm and the left M1 segments were a little longer. The mean volume of the M1 segments was 63.92 mm(3) , and this was typically greater in men and on the left sides. The mean TI and DI for the M1 segment were 0.91 and 2.17 mm, respectively. Therefore, the M1 segments are only slightly curved or straight in their course. In addition, the longest vascular M1 segments are more deviated (curved) and more tortuous. Such standardized data as presented herein may be useful in the preprocedural evaluation of patients with intracranial vascular pathology of the M1 segment.
