Abstract

Purpose: The anterior communicating artery complex (ACAC) comprises the A1 and A2 segments of the anterior cerebral artery (ACA) and the anterior communicating artery (ACoA). It is a common site for aneurysms and variations in anterior cerebral circulation. With ongoing advancements in endovascular intervention, there is an increasing need for detailed anatomical knowledge of the ACAC. This study was conducted to explore the anatomical measurements, including the length and diameter, of the ACAC in a South African population.

Method: The study involved the analysis of 200 adult magnetic resonance angiogram (MRA) scans (145 female, 55 male) from Groote Schuur Hospital, Department of Radiology, where the internal length and diameter of ACAC vessels were obtained.

Results: The average internal length of the right and left A1 ACA segments was 13.5 (3.48) mm and 12.85 (2.57) mm, respectively. The internal diameter of the right and left ACA was 2.26 (0.45) mm and 2.25 (0.68) mm, respectively. For the A2 ACA, the average internal length for the right A2 ACA was 23.4 (3.94) mm, and the left A2 ACA had an average internal length of 23.7 (3.97) mm. The average internal diameter for the right and left A2 ACA was 2.3 (0.33) mm and 2.37 (0.78) mm, respectively. For ACoA, the average internal length was 1.5 (1.76) mm, and the average diameter was 0.85 (0.91) mm.

Conclusion: The morphometric parameters of the ACAC measured in this study were within similar ranges to those reported in previous international and national studies.

前交通动脉复合体形态的血管造影研究-一个南非样本。

目的：前交通动脉复合体（ACAC）由大脑前动脉（ACA）和前交通动脉（ACoA）的A1段和A2段组成。它是动脉瘤和大脑前循环变异的常见部位。随着血管内介入技术的不断进步，对ACAC详细解剖知识的需求日益增加。本研究旨在探讨南非人群中ACAC的解剖测量，包括长度和直径。方法：对grote Schuur医院放射科200例成人磁共振血管造影（MRA）扫描（女性145例，男性55例）进行分析，获得ACAC血管的内部长度和直径。结果：左、右A1 ACA节段内平均长度分别为13.5 (3.48)mm和12.85 (2.57)mm。左、右ACA内径分别为2.26 (0.45)mm和2.25 (0.68)mm。右侧A2 ACA的平均内长为23.4 (3.94)mm，左侧A2 ACA的平均内长为23.7 (3.97)mm，右侧和左侧A2 ACA的平均内径分别为2.3 (0.33)mm和2.37 (0.78)mm。ACoA的平均内长为1.5 (1.76)mm，平均直径为0.85 (0.91)mm。结论：本研究测量的ACoA的形态计量学参数与国际和国内已有的研究结果基本一致。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
