Abstract
Purpose: The anatomy of the abdominal aorta (AA) varies with age and sex; however, limited studies exist from South Africa. Given the increased incidence of endovascular treatment of the AA, reference values are relevant for interventionalists for improving the safety of endovascular procedures. Therefore, the study aimed to determine the lengths, diameters and tortuosity of the AA and their association with age and sex in a South African sample.
Methods: After ethical approval, 97 computed tomography angiography (CTA) scans from an adult sample (54 male and 43 female), mean age 48.5 ± 17.2 years were analysed. The aortic length was measured from the origin of the coeliac trunk to the bifurcation point of the AA. The lumen diameters of the aorta were measured at three landmarks. Tortuosity of the AA was quantified with the tortuosity index and its prevalence was determined.
Results: The AA was longer in males and showed a significant weak positive correlation with age. The mean diameters of the AA were larger in males and had a significant strong positive correlation with age in both sexes (p < .001). There was a strong positive correlation between age and tortuosity in both sexes (p < .001). The prevalence of a tortuous c-shaped-curve phenotype was 8.2%, with a 7:1 male-to-female ratio.
Conclusion: The dimensions and tortuosity differed between sexes and varied significantly with age. These findings may contribute towards reference values in the South African setting, inform patient selection and complement decision-making of endovascular treatment strategies.
目的：腹主动脉（AA）的解剖结构因年龄和性别而异；但南非的研究有限。鉴于腹主动脉瘤血管内治疗的发生率越来越高，参考值对于介入医师提高血管内手术的安全性非常重要。因此，本研究旨在确定南非样本中 AA 的长度、直径和迂曲度及其与年龄和性别的关系：在获得伦理批准后，研究人员分析了来自成年样本（54 名男性和 43 名女性）的 97 张计算机断层扫描血管造影 (CTA) 扫描图像，样本的平均年龄为 48.5 ± 17.2 岁。主动脉长度的测量是从腹腔干的起源点到 AA 的分叉点。在三个地标处测量了主动脉的管腔直径。用迂曲指数量化 AA 的迂曲程度，并确定其发生率：结果：男性的 AA 较长，且与年龄呈显著的弱正相关。男性 AA 的平均直径更大，与年龄呈显著的强正相关（p 结论：男性 AA 的平均直径更大，与年龄呈显著的强正相关：不同性别的动脉尺寸和迂曲度存在差异，并随年龄的增长而显著变化。这些研究结果有助于为南非的情况提供参考值，为患者的选择提供信息，并为血管内治疗策略的决策提供补充。
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.
