Pulmonary Artery Stenting as a Treatment for Severe Stenosis Caused by Fibrosing Mediastinitis

An 86-year-old female had dyspnea, and was diagnosed with fibrosing mediastinitis. Pulmonary angiography revealed 100% left PA occlusion, and 80% proximal right PA stenosis. There was a 50mmHg trans-stenosis pressure gradient. A right PA stent was placed. The trans-stenosis pressure gradient improved to 24mmHg; this was sustained 2.5 months after stent placement, and the stent remained patent after 11 months. The patient's dyspnea improved, andremained so 14 months after stenting.
