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.
一名75岁男性，患有包裹主动脉弓和肺动脉的侵袭性胸腺瘤，因呼吸困难1年且右心衰竭加重转诊至我院。肺动脉造影显示右肺动脉狭窄超过90%。进行了球囊血管成形术和支架置入术，患者的呼吸急促和外周水肿立即得到改善。在完成血管造影时，肺部混浊有所改善，支架保持通畅，直到患者2年后因癌症相关并发症死亡。对于非先天性狭窄原因导致的肺动脉支架置入术是一种安全有效的治疗方法。
