Abstract
MENDES, Lígia et al. Abdominal aortic aneurysm prevalence in patients with significant hemdynamically carotid stenosis. Angiol Cir Vasc [online]. 2018, vol.14, n.2, pp.14-20. ISSN 1646-706X.
Introduction: Abdominal aortic aneurysm (AAA) and carotid stenosis (CS) are manifestations of atherosclerotic disease. Besides common risk factors, both diseases have an identical genetic expression related to oxygen transport and the erythrocyte membrane. Objectives: Studying the association between AAA and CS≥50%; estimating the prevalence of aneurysmal disease in patients with CS; determining the prevalence of risk factors more frequently associated with CS. Material and Methods: We executed a transversal, retrospective and observational study. We studied a population of 526 men who realized carotid ultrasound from January 2013 to December 2014. We evaluated the following variables: presence and characteristics of AAA; smoking; SC degree and history of carotid endarterectomy and a score of risk for AAA. The statistical analysis was obtained by IBM SPSS Statistics 21 software. Results: The mean age was 68,7 ± 8,84 years and 329 patients (62,5%) were more than 65 years. Concerning risk factors, 298 (56,7%) were smokers. Of the 526 patients, 191 (36,3%) had CS≥50% or had made carotid endarterectomy. The prevalence of AAA in patients with CS≥50% was 19,4%. We verified the statistical evidence to affirm the association between AAA and CS≥50% (p=0,009). We didn't verify evidence between AAA and the different levels of CS≥50% (p=0,115). We observed an association between advanced age and AAA (p=0,034). We didn't verify the statistical evidence to affirm an association between AAA and smoking (p=0,783). We didn't find association score of risk and the prevalence of AAA (p=0,300). Conclusion: This study highlights the importance of excluding aneurismal disease in patients with CS.
