Abstract:
Objective:To investigate the risk factors related to the contrast-induced nephropathy(CIN)occurring after carotid artery stenting(CAS)in patients with carotid artery stenosis.Methods:The clinical data of 137 patients with carotid artery stenosis, who were treated with CAS at Xuanwu Hospital, Capital Medical University during the period from January to Decmber 2021 were retrospectively analyzed. Record demographic characteristics (age, gender, height, weight), history of underlying diseases (hypertension, diabetes, kidney disease, etc.), history of medications, etc. Observe the clinical parameters such as creatinine, blood urea nitrogen, albumin, hemoglobin, hematocrit, degree of stenosis and estimated glomerular filtration rate (eGFR). Measurement data conforming to the normal distribution were expressed as the mean±standard deviation( ± s), and the t-test was used for comparison between groups; the measurement data that does not conform to the normal distribution were expressed as the median (interquartile range) [ M( Q1, Q3)], and the Rank-sum test was used for comparison between groups; the Chi-square test or Fisher exact test was used for comparison of count data between groups. Relevant variables were subjected to univariate analysis, and statistically significant indicators were selected according to the results of univariate analysis to be included in the multivariate Logistic regression analysis. Results:After CAS, a total of 29 patients (21.2%) among the 137 patients developed CIN. Univariate analysis indicated that bilateral carotid artery stenosis, uncontrolled hypertension before surgery, history of angiotensin converting enzyme inhibitor drugs, diabetes mellitus, history of insulin drugs, eGFR<45 mL/(min·1.73 m 2), body weight were the influencing factors associated with the occurrence of CIN after CAS in patients with carotid artery stenting; multivariate regression analysis revealed that the presence of bilateral carotid artery stenosis( OR=4.724, 95% CI: 1.455-15.338, P=0.010), diabetes mellitus( OR=3.451, 95% CI: 1.345-8.858, P=0.010) and eGFR <45 mL/(min·1.73 m 2)( OR=4.582, 95% CI: 1.001-20.971, P=0.050) were the independent risk factors related to the CIN after CAS. Conclusion:Patients with the presence of bilateral carotid artery stenosis, diabetes mellitus or eGFR <45 mL/(min·1.73 m 2) are more likely to develop CIN after CAS.
