Objective : To determine whether intravenous infusion of low dose of streptokinase was effective in lysing umbilical arterial catheter (UAC)‐associated aortic thrombi. Method : A prospective cohort study of 31 consecutive newborn infants with UAC‐associated aortic thrombi which were detected by abdominal ultrasonography after removal of UAC. Twenty‐two infants were treated with intravenous infusion of low dose (1000 U/h) streptokinase, while nine others were not treated due to various contra‐indications. Thrombolysis occurred after a mean interval of 2.2 days (standard deviation (SD) = 1.8) in the treated infants. In the untreated infants, spontaneous thrombolysis occurred significantly later, after a mean interval of 16.9 days (SD = 14.7) (95% confidence intervals of difference between mean intervals – 26.0, – 3.4; P = 0.02). Only one treated infant developed mild bleeding directly attributed to streptokinase therapy. Conclusion : Low dose streptokinase infusion was effective and safe in thrombolysing UAC‐associated aortic thrombi.
