Developing a pediatric endovascular thrombolysis program: a single-center experience.

Deep venous thrombosis (DVT) is being increasingly recognized as a significant issue in children. Despite the low incidence of DVT, the risks of pulmonary embolism and death in children are significant. Post-thrombotic syndrome, a syndrome of chronic venous insufficiency, can have long-term adverse consequences in children and adolescents. Adult studies have shown that catheter-directed therapy can reduce the incidence of post-thrombotic syndrome. Safety of catheter-directed therapy in adolescents has also been demonstrated. These reasons compelled us to institute a pediatric endovascular thrombolysis program at our institute for management of pediatric DVT. We describe the process of developing a multi-disciplinary thrombolysis program involving interventional radiology (pediatric and adult), pediatric hematology, critical care, anesthesia and vascular surgery, and describe the role of each specialty in the development of the program. We also describe our experience with patient selection, endovascular therapy procedure, pre-, intra- and post-procedure monitoring, and follow-up management for endovascular therapy for DVT.
