ABSTRACT
Introduction. The aim of this study was to examine the incidence and risk factors of catheterization-related CI in the contemporary era, using diffusion-weighted magnetic resonance imaging. Methods. We retrospectively analyzed consecutive 84 patients who underwent MRI (magnetic resonance imaging) after 2.81 ± 2.4 days (mean ± SD) of catheterization via aortic arch. We categorized the patients by the presence or absence of acute CI determined by diffusion-weighted MRI and analyzed the incidence and predictors. Results. Of 84 patients that underwent MRI after catheterization, acute CI was determined in 27 (32.1%) patients. In univariate analysis, dyslipidemia, age, coronary artery disease, antiplatelet agents, number of catheters used, urgent settings, and interventional procedures were significantly different. Multivariate analysis revealed dyslipidemia (odds ratio [OR], 4.46; 95% confidence interval [CI], 1.41-16.03; p = 0.01), higher age (OR, 1.09; 95% CI, 1.007-1.19; p = 0.03), and the number of catheters used (OR, 2.21; 95% CI, 1.21-4.36; p = 0.01) as independent predictors of the incidence of catheterization-related acute CI. Conclusions. Dyslipidemia, higher age, and number of catheters used were independent predictors for acute CI after catheterization. These findings imply that managing dyslipidemia and comprehensive planning to minimize the numbers of catheters are important.

Mentions: Among a total of 1237 catheterization procedures, 84 patients (56 men and 28 women; mean age, 71.6 ± 8.7 years) who underwent MRI within 14 days after catheterization (mean duration, 2.81 ± 2.4 days) were included in the study. A flowchart of the study population is shown in Figure 1. DW MRI revealed acute CI in 27 of 84 patients (32.1%). No patient revealed a hemorrhagic lesion. Among 1237 catheterization procedures, 3 patients and 1 patient were clinically diagnosed as stroke and TIA, respectively. We categorized the study subjects into two groups according to the presence or absence of acute CI and compared the patient and procedural characteristics between them (Tables 2 and 3).
