AbstractRecent studies have demonstrated the risk of contrast-associated acute kidney injury (CA-AKI) is low post-multimodal computed tomography (MMCT) in the evaluation of acute stroke. We provide a complementary study with long-term renal follow up. A retrospective analysis was performed on all suspected strokes from January 2019 to June 2020 for those who had undergone computed tomography angiography, computed tomography perfusion or both. We identified 776 cases, of which 538 were excluded. The incidence of CA-AKI was 7.6% (n/N = 18/238; 95% confidence interval = 4.2-11.0). All CA-AKI cases had renal confounders. No AKI at >30 days was found in 60.5% (n = 144) of all cases studied. The long-term renal outcome post-MMCT in stroke evaluation is favourable at >30 days.© 2021 Royal Australasian College of Physicians.
