Effects of hypotonic nonionic contrast agents on serum creatinine,blood urea and renal function in elderly patients withischemic cerebrovascular disease
Objective To analyze the effect of serum creatinine, blood urea and renal function with angiography low permeability of non-ionic contrast agent in elderly patients with ischemic cerebrovascular disease,and provide reference for clinical treatment.Methods 100 elderly patients with ischemic cerebrovascular disease in hospital from April 2011 to May 2016 were selected,patient were given cerebrovascular, renal arteriography.The changes of serum creatinine and urea were detected at different time before and after 3 days, and the changes of renal function were detected.Results In 100 cases, 12 cases of contrast induced nephropathy, the incidence rate was 12%.Contrast nephropathy in patients with diabetes mellitus group proportion, renal insufficiency, the proportion of severe renal artery stenosis was significantly higher than the proportion of non contrast nephropathy group (P<0.05).Contrast nephropathy group contrast 1 days and contrast 2 days blood urea, serum creatinine and creatinine clearance rate were significantly increased (P<0.05), contrast to 6 days gradually returned to normal, no obvious change of non contrast nephropathy in patients with renal function index.Diabetes mellitus (OR=6.973), severe renal artery stenosis (OR=4.286) and renal insufficiency (OR=7.680) are the risk factors of contrast induced nephropathy (P<0.05).Conclusion Vascular elderly patients with ischemic cerebrovascular disease using non-ionic contrast medium hypotonic angiography safer, diabetes, renal patients need to continue to pay attention to changes in renal function.
