Abstract

Background: A reverse Potts shunt is performed as a palliative intervention for severe pulmonary hypertension (PH) to decompress the right ventricle. Several reports have described transcatheter stenting of the patent ductus arteriosus (PDA) to create an endogenous Potts shunt in infants with severe PH, typically via the femoral vein approach. Case Description: We present the case of a 7-month-old, 7.5 kg female infant diagnosed with severe PH dependent on PDA circulation, who was treated with PDA stenting via the right internal jugular vein (RIJV) approach due to inferior vena cava occlusion. A veno-arterial wire loop was created from the femoral artery to the RIJV to stabilize the wire and stent delivery. A 6 × 14 mm stent was successfully inserted into the PDA without complications. Conclusion: The RIJV approach using the veno-arterial loop technique is a viable and effective treatment for severe PH in infants with limited vascular access.
