Abstract:
:We sonographically investigated the internal jugular veins of 40 children who had undergone catheterization of the vein (group A: silastic catheter, n = 24; group B: polyurethane catheter, n = 16) in the neonatal period. The average age at catheter implantation was 43 +/- 73 days, the average birthweight 2414 +/- 1145 g, and the average gestational age 34.8 +/- 5.0 weeks. We performed follow-up longitudinal and transverse high resolution sonographic scans including routine examination of the contralateral jugular vein at a mean age of 3.7 +/- 1.5 years. In group A thrombotic alterations were detected in 8 aut of 24 patients. In three of these patients we found mild clinical symptoms. In group B thrombotic alterations were detected in 1 aut of 16 patients without clinical symptoms. Mean birthweight (1815 versus 3313 g) and mean gestational age (32.3 versus 38 weeks) were significantly lower and indwelling time of the catheters (18 versus 11 days) was significantly longer in group A. Our results indicate that jugular vein thrombosis is a frequent long-term complication in neonates after jugular vein catheterization. High resolution ultrasonography is an adequate method for detecting jugular vein thrombosis and should therefore routinely be performed for long-term follow-up.
