Abstract

Background: The aneurysm refers to the increase in arterial diameter in a localised position and this is characterised by the non-parallelism of the arterial wall. Despite prediction models trying to anticipate the onset of an aneurysm, the limits of their accuracy are often reached. This is due to the poor definition of the factors favouring the development of the aneurysm. In order to take into account this complex process, this study proposes a fuzzy system in the analysis of the effect of each factor. Methods: As the variability of the diameter of the aorta is a function of several uncertain and imprecise factors, this study deals with data relating to a population of 100 patients diagnosed at the level of the service of the UFAS Setif Hospital in Algeria. This study is limited to the effect of age, which is related to the diameter of the abdominal aorta diagnosed. A fuzzy inference analysis system is proposed. As the system is very complex and in an uncertain environment, its fuzzy logic analysis compensates this uncertainty. Results: Once the system is established from the actual values recorded, it becomes possible to introduce the input variables randomly to automatically read the result at the output with maximum precision. Conclusions: In order to avoid the risk of rupture, it is necessary to diagnose the aneurysm according to the patient's age. The introduction of the variables relating to the patient at the entry of the system allows clinicians to have a precise idea about the aneurysm. Note that the majority of cases are diagnosed accidentally in the absence of a screening program.
年龄对腹主动脉瘤的影响:模糊逻辑分析
背景:动脉瘤是指在局部位置动脉直径增加,其特征是动脉壁不平行。尽管预测模型试图预测动脉瘤的发生,但其准确性往往达到极限。这是由于对有利于动脉瘤发展的因素定义不清所致。为了考虑到这一复杂的过程,本研究提出了一个模糊系统来分析各因素的影响。方法:由于主动脉直径的变异性是几个不确定和不精确因素的函数,本研究处理与阿尔及利亚UFAS Setif医院服务水平诊断的100例患者相关的数据。本研究仅限于年龄的影响,年龄与腹主动脉的直径诊断有关。提出了一种模糊推理分析系统。由于系统非常复杂且处于不确定环境中,其模糊逻辑分析弥补了这种不确定性。结果:一旦根据实际记录的值建立系统,就可以随机引入输入变量,以最大精度自动读取输出结果。结论:为避免动脉瘤破裂的风险,有必要根据患者的年龄对动脉瘤进行诊断。在系统入口引入与患者相关的变量,使临床医生能够对动脉瘤有一个精确的了解。请注意,大多数病例是在没有筛查程序的情况下意外诊断出来的。
