Pulmonary vein (PV) radiofrequency ablation (RFA) is an effective technique for a selected group of patients with atrial fibrillation (AF) refractory to antiarrhythmic drugs (Alfudhili et al., 2017). However, pulmonary vein occlusion is a potentially rare, sometimes severe, complication which may present clinically as nonspecific respiratory symptoms, signifying pulmonary vein stenosis, that are often underrecognized or misdiagnosed, leading to progression of the low-grade stenosis to complete occlusion if not treated with timely intervention (Alfudhili et al., 2017). . We report the first case of haemoptysis, three months postradiofrequency ablation (i.e., late complication) secondary to pulmonary vein occlusion that was diagnosed by computed tomography angiogram (CTA), which showed occlusion of 2 out of 4 native pulmonary veins.
The cause of haemoptysis in this patient was pulmonary vein occlusion, secondary to radiofrequency ablation, as demonstrated in the CTA.
肺静脉（PV）射频消融术（RFA）是一种针对特定一组对抗心律失常药物难治的心房颤动（AF）患者的有效技术（Alfudhili等人，2017年）。然而，肺静脉闭塞是一种潜在的罕见、有时严重的并发症，临床上可能表现为非特异性呼吸道症状，提示肺静脉狭窄，这些症状常常未被充分认识或误诊，如果不及时干预治疗，会导致低度狭窄进展为完全闭塞（Alfudhili等人，2017年）。我们报告了首例射频消融术后三个月（即晚期并发症）因肺静脉闭塞导致咯血的病例，该病例通过计算机断层血管造影（CTA）诊断，显示4条肺静脉中的2条闭塞。
如CTA所示，该患者咯血的原因是射频消融术后继发的肺静脉闭塞。
