Incidental Visceral and Renal Artery Stenosis in Patients Undergoing Coronary Angiography

Abstract

Purpose The study aimed to examine the association between incidentally discovered mesenteric artery stenosis, renal artery stenosis (RAS) and coronary artery disease in patients undergoing coronary angiography. Materials and methods We performed a prospective analysis of consecutive patients undergoing routine cardiac catheterisation. Abdominal aortograms in lateral and antero-posterior view were obtained to assess arterial stenosis of the coeliac axis, superior mesenteric artery and renal arteries. Significant arterial stenosis was defined as a narrowing of at least 50% compared with the normal artery. Demographic data and cardiovascular risk factors were analysed. Results The prevalence of visceral artery stenosis (VAS) was 63/450 (14%) including 48/450 (10.6%) cases of coeliac axis stenosis and 15/450 (3.3%) cases of superior mesenteric artery stenosis. Female sex ( p = 0.01), older age ( p = 0.03) and the presence of coronary artery disease ( p = 0.05) were significant predictors for the presence of VAS in univariate analysis. The determinants for VAS in multivariate analysis were female sex and three-vessel coronary artery disease, while two- and three-vessel coronary artery disease was significant for RAS. Conclusion Screening for VAS and RAS in female patients older than 60 years with more than two diseased coronary segments could have a high diagnostic value.
