To report our institutional experience with iliofemoral stent placement in pediatric patients with recurrent iliofemoral venous thrombosis and stenosis refractory to angioplasty and endovascular thrombus removal (ETR). Aninstitutional review board–approved single-institution retrospective studyof pediatric patients (< 18 years of age) who underwent iliofemoral venous stenting between January 2012 and December 2022. Patient demographics, associated risk factors, presenting symptoms, and procedural characteristics were recorded. These characteristics include the technical success rate, types of devices used, the number of cases reviewed before deciding on stent placement, and the total case count. The primary outcome was stent patency rates at imaging follow-up. 73 procedures were performed on 17 patients.The cohort had an average age of 14.6 years (range 7-17), a mean weight of 74.1 kg (range 38-128.7), and a mean BMI of 29. 14 patients presented with acute iliofemoral DVT, 2 with chronic DVT, and 1 with left lower extremity swelling without thrombosis. Patients underwent an average of 3 procedures over a mean of 2.8 months (range 0-17 mo) prior to committing to a stent. Technical success was achieved in all cases (n = 17). No periprocedural complications were recorded. The median follow-up length was 18 months (range, 1-77 mo). Primary and secondary patency rates were 76% and 100% at 12 months and 71% and 100% at 24 months, respectively. Iliofemoral stenting in pediatric patients experiencing recurrent thrombosis or stenosis is a significant clinical challenge. Our institutional experience suggests iliofemoral stent placement can be a safe and durable intervention in the pediatric population when other therapeutic options have failed.
