BackgroundThe endovascular coiling procedure to treat cerebral aneurysms using contrast media has become more popular. However, studies of the incidence of, and risk factors for, contrast media-induced nephropathy (CIN) after coiling procedures have been limited. Thus, we evaluated the incidence and risk factors for CIN in patients who had undergone cerebral aneurysmal coiling procedures.MethodsWe retrospectively reviewed the electric medical records of 380 patients who had undergone cerebral aneurysmal coiling treatment under general anesthesia. CIN was defined as an absolute increase in serum creatinine (≥0.5 mg/dL) or a relative increase (≥25%) in the baseline serum creatinine value at 48-72 hours after exposure to a contrast agent.ResultsElective cerebral aneurysmal coiling procedures were performed in 230 patients. Of the 230 patients, CIN developed in 13 (5.6%). The presence of diabetes mellitus (30.8% vs. 9.7%; P = 0.040) and patient age >75 years (30.8% vs. 6.5%; P = 0.012) were risk factors for CIN.ConclusionsOur study has demonstrated that the incidence of CIN in patients undergoing elective cerebral aneurysmal coiling procedures is ∼6.0%. We also identified underlying diabetes mellitus and advanced age (≥75 years) as potential risk factors.Copyright © 2018 Elsevier Inc. All rights reserved.
