Purpose:To evaluate the thrombolytic effect of transcatheter intra-arterial infusion of urokinase injectio salviae miltiorrhizae and heparine.Materials and methods:A 5F catheter was delivered to the thrombotic site via femoral artery,then infused urokinase.Injectio salviae mihionrrhizae via catheter.During and after the procedure heparin was given for antico- agulation.Finally to evaluate the effect by femoral arteriograms.Results:Blood circulation of 10 eases were inproved with complete pateney.One case wasn't very fluent and the last one remained obstructed.Total effective rate was 92%.Conclusion:Transcatheter Intraarterial thrombolysis by combing urokinase,injeetio salviae miltiorrhizae and heparin was a effective and safe theraputic method.
