Abstract

We report the case of a 71-year-old woman with pulmonary artery occlusion due to fibrosing mediastinitis who successfully underwent computed tomographic optimal fluoroscopic projection angle-guided stenting of the pulmonary artery.

Enhanced computed tomography showed stenosis of pulmonary artery (red arrow) and pulmonary vein (white arrow) compressed by proliferative fibrotic tissues (yellow dots) in mediastinum (A).preoperative CTPA showed stenosis of the left lower pulmonary artery trunk (orange arrow) and severe stenosis of the left pulmonary artery (red arrow) (B).Selective pulmonary artery arteriography showed stenosis of the left lower pulmonary artery trunk (orange arrow) and severe stenosis of the left pulmonary artery (red arrow) (C).Selective pulmonary artery angiography showed stenting in the left lower pulmonary artery trunk (orange arrow) and left pulmonary artery (red arrow) (D).
