[Gadodiamide and carbon dioxide as alternative contrast media in patients with chronic renal failure]

Twelve diagnostic and therapeutic angiograms were performed in 10 patients with chronic renal failure using gadodiamide and CO2 as vascular contrast. Renal function was evaluated with serum creatinine levels 24 hours before and 24 to 48 hours after the vascular procedure. Imaging quality and tolerance of these contrast agents were also studied. There was no significant increase in serum creatinine levels in the 12 procedures. In all cases but one, the combined use of gadodiamide and CO2 offered images of enough quality and definition for diagnosis and therapy. A good symptomatic tolerance was present in all procedures. Gadodiamide and CO2 seem to represent useful and safe contrast agents for angiography and endovascular intervention in patients with chronic renal failure. Further experience is needed to confirm these initial findings.
