Percutaneous stenting of the pulmonary artery is a diffuse procedure, above all in patients with congenital heart disease. The effectiveness of the procedure is associated with potential and feared complications. This case describes the embolization of a premounted stent into the left lower lobe pulmonary artery in a 3-years old patient with univentricular heart and left-side superior vena cava undergone to Norwood procedure modified according to Sano (stage I) and then bilateral cavo-pulmonary anastomosis according to Glenn (stage II). The retrieval procedures were complicated by the severe hypoplasia of the left pulmonary artery and by the complex anatomy of the patient. This case shows how to pull-back an embolized stent in a child with a complex congenital heart disease despite the limitations related to the low weight and the complex vascular anatomy.
