Although a site common for pathology and of great importance to the neurosurgeon, the three-dimensional (3D) morphometry of the anterior communicating artery (ACoA) has had incomplete descriptions in the literature.
Using a novel 3D digital-image computer data analysis system, 115 patients underwent evaluation of their ACoA based on DICOM files derived from CT angiography. Measurements included the length, internal diameter, volume, deviation index (DI) and tortuosity index (TI).
Of 115 samples, 85 were visualized clearly enough for morphometric analysis. The mean internal diameter was 1.86 mm and this tended to be greater in males (P < 0.05). The mean length of the ACoA was 3.99 mm and the mean volume was 11.61 mm(3). The mean TI for the ACoA was 0.84 and the mean DI was 0.62 mm. A significant relationship between DI and length, DI and volume, and DI and TI were found. The significant correlation of diameter to volume, and length related to volume, DI and TI, as well as TI related to length, volume and DI were noticed. There were no relationship between any parameter and age.
A detailed knowledge of the 3D-morphometry of the ACoA demonstrates that in almost 50% of individuals the ACoA is straight in their course. Detailed data regarding arterial topography and trajectory as found in our study may be also of use in detecting early changes in this vessel due to pathology and may assist in the treatment of vascular lesions and planning of neurosurgical or interventional radiological procedures in the region including ACoA aneurysms.
前交通动脉（ACoA）虽是病理学上常见且对神经外科医生极为重要的部位，但其三维（3D）形态测量在文献中的描述并不完整。
使用一种新型的3D数字图像计算机数据分析系统，基于CT血管造影获得的DICOM文件，对115例患者的ACoA进行评估。测量内容包括长度、内径、体积、偏差指数（DI）和迂曲指数（TI）。
115个样本中，85个样本的可视化效果足以进行形态测量分析。平均内径为1.86mm，男性的内径往往更大（P<0.05）。ACoA的平均长度为3.99mm，平均体积为11.61mm³。ACoA的平均TI为0.84，平均DI为0.62mm。发现DI与长度、DI与体积、DI与TI之间存在显著关系。注意到直径与体积、长度与体积、DI和TI之间，以及TI与长度、体积和DI之间存在显著相关性。任何参数与年龄之间均无关系。
对ACoA的3D形态测量的详细了解表明，在近50%的个体中，ACoA在走行过程中是直的。我们研究中发现的有关动脉形态和走行轨迹的详细数据，可能也有助于检测该血管因病变而出现的早期变化，并可能有助于治疗血管病变以及规划包括ACoA动脉瘤在内的该区域的神经外科手术或介入放射学操作。
