To evaluate the clinical findings and ultrasonographic findings of aortic thrombosis which developed after umblical artery catheterization in neonates.
We retrospectively evaluated clnical records and ultrasonographic findings in five cases of aortic thrombosis, which developed after umblical artery catheterization. Four were premature newborns, and one was a term neonate but small for gestational age. Three were male infants. The mean age was 29.8 days (15-71 days) and the duration of umblical artery catheterization was 16.4 days (7-31 days). The gestational age of 5 cases was between 26 and 38 weeks (mean 33 weeks) and birth weight was between 930 and 2,600 g (mean 1,950 g). All cases were diagnosed by ultrasonography only, and in 2 cases color Doppler ultrasonography was performed additionally.
There were several associated conditions including hypothermia (n=2), perinatal asphyxia (n=2), respiratory distress syndrome (n=5), and neonatal infection (n=5). The clinical manifestations of 5 cases were hypertension (n=4), thrombocytopenia (n=4), hematuria (n=2), renal failure (n=l), and congestive heart failure (n=l). In all five cases, ultrasonography showed hyperechoic thrombus with partial occulsion of aorta. The size of thrombi varied 1.2-4x 4-25 mm. All thrombi were located around the origin site of renal artery.
Aortic thrombosis, one of the complications of umblical artery catheterization can easily be diagnosed by ultrasonography, so ultrasonography would be needed as a screening study in neonate with umblical artery catheterization.
