Endovascular management of pulmonary artery stenosis due to tumor compression.

A 75-year-old man with invasive thymoma encasing the aortic arch and pulmonary arteries was referred to our institution with a 1-year history of dyspnea and worsening right heart failure. Pulmonary angiogram demonstrated greater than 90% stenosis of the right pulmonary artery. Balloon angioplasty and stent placement were performed with immediate improvement in his shortness of breath and peripheral edema. Improved lung opacification was noted on completion arteriography, and the stents remained patent until the patient expired from complications related to his cancer 2 years later. Pulmonary artery stenting in noncongenital causes of stenosis is a safe and effective therapy.
