    Abstract:
    PURPOSE: To evaluate the safety and efficacy of iodixanol (Visipaque) in phlebography in order to obtain experience from the use of this contrast medium in this i.v. indication. PATIENTS AND METHODS: Phlebography was performed in 150 patients, as a comparative prospective, double-blind, randomized parallel group study comparing iodixanol 270 mgI/ml with ioxaglate 320 mgI/ml. The tolerability was assessed from occurrence of discomfort, adverse events up to 30 min following injection and late adverse events. Efficacy was assessed by recording the diagnostic information on each venous segment. Statistical analysis was performed using the Cochran-Mantel-Haenszel test in order to correct for a possible centre effect. RESULTS: Frequency of patients reporting discomfort (P=0.002) or adverse events (P<0.001) was statistically significantly lower after the injection of iodixanol than after ioxaglate. There was no statistical difference regarding late adverse events and diagnostic information. CONCLUSION: Iodixanol 270 mgI/ml yielded the same diagnostic information as ioxaglate 320 mgI/ml and was associated with fewer patients reporting adverse events and discomfort.
