We report our acute and intermediate results.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>All patients with systemic venous stent placement in the iliofemoral veins, inferior or superior vena cava at our institution between 1998 and 2006 were included. Initial and the follow\u2010up catheterization data were reviewed retrospectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>70 stents were placed in 33 patients (36 vessels). Median age was 2.6 years (0.2\u201314.2) and weight 11.5 kg (3.8\u201378.7). 17\/36 vessels (47%) were occluded requiring recanalization. Following stent delivery, the mean minimum vessel diameter increased from 3.1 \u00b1 3.2 to 7.2 \u00b1 3.0 mm (<jats:italic>P<\/jats:italic> &lt; 0.001). There were no major complications. Seventeen patients and vessels had a total of 62 follow\u2010up catheterizations, with median length of follow\u2010up 4.1 years (0.7\u20139.3). During intermediate follow up, 7\/17 vessels (41%) required additional intervention. Six patients had additional balloon dilation of existing stents, and one additional stent was placed. Vessels were further dilated to 8.4 \u00b1 3.5 mm at the last catheterization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>Systemic venous stents are safe and effective in recanalizing stenosed or occluded vessels. At follow\u2010up, reocclusion can occur, however, previously placed stents can be safely recanalized if necessary. Future studies will determine if stenting is indicated in a broader population. \u00a9 2009 Wiley\u2010Liss,
