Purpose: The purpose of this study was to investigate whether anticoagulation (AC) results in thrombus resolution and increased line longevity in children with intestinal failure (IF) and catheter-associated central venous thrombosis (CVT). Methods: A retrospective, single institution review was performed of children with IF who were dependent on parenteral nutrition with known CVT between 2006 and 2017. Frequency of catheter-related complications including infection, occlusion, and breakage were compared 18 months prior to and after starting AC. Thrombus resolution during anticoagulation was also determined. Data were analyzed using Poisson regression. p-Values < 0.05 were considered significant. Results: Eighteen children had ≥ 1 CVT, with the subclavian vein most commonly thrombosed (44%). All children were treated with low molecular weight heparin, and 6 patients (33%) had clot resolution on re-imaging while receiving AC. Bloodstream infections decreased from 7.9 to 4.4 per 1000 catheter days during AC (p = 0.01), and the number of infections requiring catheter replacement decreased from 3.0 to 1.0 per 1000 catheter days (p = 0.01). There were no significant differences in line occlusions or breakages. Conclusion: Anticoagulation for children with intestinal failure and central venous thrombosis may prevent thrombus propagation, and decrease blood stream infections and line replacements. Further research is needed to determine optimal dosing and duration of therapy. Level of Evidence: III; Retrospective Comparative Study.
