Pulmonary vein stenosis is a rare but severe complication of catheter ablation for arterial fibrillation (AF). Symptoms include dyspnea, hemoptysis, recurrent pneumonia, and pulmonary hypertension. We herein discuss a 27-year-old male patient who presented with hemoptysis and dyspnea three months after catheter ablation for AF. Computed tomography demonstrated an occluded left inferior pulmonary vein (LIPV) and left lower lung edema secondary to severe stenosis of the LIPV. The patient underwent treatment, including drug-coated balloon (DCB) venoplasty. Treatment of pulmonary vein stenosis involving percutaneous interventions with balloon angioplasty and stenting carry a high risk of restenosis. DCB therapy may be used to prevent stenosis. < The use of a drug-coated balloon is feasible and may provide good long-term outcomes in acquired pulmonary vein stenosis after radiofrequency ablation.>.
肺静脉狭窄是心房颤动（AF）导管消融术后一种罕见但严重的并发症。症状包括呼吸困难、咯血、反复肺炎和肺动脉高压。我们在此讨论一名27岁男性患者，他在AF导管消融术后三个月出现咯血和呼吸困难。计算机断层扫描显示左下肺静脉（LIPV）闭塞，继发于LIPV严重狭窄的左下肺水肿。该患者接受了包括药物涂层球囊（DCB）血管成形术在内的治疗。涉及球囊血管成形术和支架置入的经皮介入治疗肺静脉狭窄有很高的再狭窄风险。DCB治疗可用于预防狭窄。<使用药物涂层球囊是可行的，并且可能在射频消融术后获得性肺静脉狭窄中提供良好的长期结果。>
