title: Endovascular covered stent repair of an iatrogenic subclavian artery-to-pulmonary artery fistula and pseudoaneurysm.
abstract: An iatrogenic fistula and consequent pseudoaneurysm developed between the right subclavian artery and right pulmonary artery as a result of misplacement of a hemodialysis access catheter. The patient, who was considered to be at high risk for surgical repair, successfully underwent endovascular treatment that involved insertion of two nitinol stents covered with expanded polytetrafluoroethylene (stent-grafts), one into the right subclavian artery and the other into a right upper lobe pulmonary artery. Multi-detector row computed tomographic angiography played an integral role in the evaluation of the patient's vascular injury and treatment planning.
