Traumatic ascending aortopulmonary window following pulmonary artery stent dilatation: therapy with aortic endovascular stent graft.

Endovascular stent grafts have become an established therapy in adults for descending thoracic aortic disease. We report a case of a 13-year-old boy with a hemodynamically significant traumatic aortopulmonary window following angioplasty of pulmonary artery stent. Endovascular stent graft implantation into the ascending aorta was performed to seal off the communication, with dramatic hemodynamic improvement.
