Abstract
Objective To determine whether superior vena cava (SVC) stent implantation is superior to balloon angioplasty for relieving SVC stenosis. Background SVC stent and balloon dilation have been used as treatment for SVC stenosis. Although safe and effective, outcome data comparing the two methods are limited. Methods A Pediatric Cardiac Care Consortium review identified SVC stenosis. Patients who required SVC intervention were divided into two subgroups - balloon dilation (Group A) and stent implantation (Group B). Logistic regression and the log-rank test were used to test the need for re-intervention within 6 months after the initial procedure. Results SVC intervention was performed on 210/637 patients with SVC stenosis (33%). There were 108/210 (51%) patients with balloon dilation (Group A) and 102/210 (49%) with stent implantation (Group B). Re-intervention within 6 months of the initial intervention was more common in Group A compared to Group B [Group A = 31/40 (77.5%); Group B = 5/22 (22.7%)]. The odds-ratio for re-intervention within 6 months of the initial procedure for balloon vs. stent, is 7.3 [95% CI: (2.91, 22.3), P < 0.0001]. In addition, during the first 6 months after an intervention for SVC stenosis the proportion of patients with stent implantation that remained free of re-intervention was significantly higher than after balloon angioplasty (log-rank test, P < 0.0001). Neither age nor weight was significantly associated with the need for re-intervention. Conclusions SVC stent implantation is more effective than angioplasty in relief of SVC obstruction. Weight and age are not risk factors for early re-intervention. © 2012 Wiley Periodicals, Inc., a Wiley company.
