Mean aortic and common iliac artery diameters are the best indicators for the diagnosis of aortic and iliac ectasia and aneurysm, as well as the appropriate selection of angiographic catheter size and grafts for endovascular procedures. Currently, there is a lack of evidence regarding the normal abdominal aortic and common iliac artery diameters in Ethiopian adults. This study aimed to assess the mean diameter and associated factors of the abdominal aorta and common iliac arteries on abdominal CT scans of Ethiopian adults visiting Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.
Institution-based prospective cross-sectional study was conducted. A convenience sampling method was employed. Data were collected from consecutive eligible adults who came for abdominal CT scans during the study period, using interviewer-administered structured questionnaires. The data was cleaned and analyzed using SPSS version 22. Student t-test and Pearson correlation were used to perform statistical analysis and the results were presented using tables and figures.
There were a total of 136 study participants of whom eighty-one(59.6%) were females and fifty-five (40.4%) were males. The mean age was 48.5 ± 13 with a range of 23 to77 years. The mean transverse diameter of the aorta at the aortic hiatus (T12)level was 2.30 ± 0.25cm in males and 2.03±0.19cm in females. The mean transverse diameter of the suprarenal aorta was 2.04 ± 0.21cm in males and 1.83 ± 0.21 cm in females while the infrarenal one was 1.77 ± 0.16cm in males and 1.54 ± 0.15cm in females. Participants who are male and older with large body Surface Area were found to have relatively larger aortic and iliac diameters.
In this study, the mean diameter of the aorta and common iliac artery was significantly associated with age, sex, and BSA.
平均主动脉和髂总动脉直径是诊断主动脉和髂动脉瘤以及血管内手术时选择合适的血管造影导管和移植物的最佳指标。目前，缺乏关于埃塞俄比亚成年人正常腹主动脉和髂总动脉直径的证据。本研究旨在评估埃塞俄比亚成年人在提克里安贝萨专科医院接受腹部 CT 扫描时腹主动脉和髂总动脉的平均直径及其相关因素。
本研究为基于机构的前瞻性横断面研究。采用便利抽样方法。在研究期间，使用访谈者管理的结构化问卷，从连续符合条件的来接受腹部 CT 扫描的成年人中收集数据。使用 SPSS 版本 22 对数据进行清理和分析。使用学生 t 检验和 Pearson 相关进行统计分析，并使用表格和图形呈现结果。
共有 136 名研究参与者，其中 81 名（59.6%）为女性，55 名（40.4%）为男性。平均年龄为 48.5 ± 13 岁，范围为 23 至 77 岁。男性主动脉峡部（T12 水平）的主动脉横径平均值为 2.30 ± 0.25cm，女性为 2.03 ± 0.19cm。男性肾上主动脉的横径平均值为 2.04 ± 0.21cm，女性为 1.83 ± 0.21cm，肾下主动脉的横径平均值为 1.77 ± 0.16cm，女性为 1.54 ± 0.15cm。男性和年龄较大且身体表面积较大的参与者的主动脉和髂动脉直径相对较大。
在这项研究中，主动脉和髂总动脉的平均直径与年龄、性别和 BSA 显著相关。
