肺隔离症是一种较为罕见的先天性肺部发育异常，既往治疗中，手术切除是其主要治疗方式。但传统手术切除并发症风险较高，患者生活质量受影响。现报道一例采用介入栓塞治疗肺隔离症合并反复咯血的患者，检查示左下肺有胸主动脉来源的2.0 cm异常供血动脉，行介入栓塞治疗。术后1个月复查栓塞满意、咯血消失，3个月随访病情稳定。介入治疗微创、恢复快，疗效优于传统手术，是肺隔离症合并咯血的优选方案，值得临床推广。

Pulmonary sequestration is a relatively rare congenital abnormality of lung development. In the past, surgical resection was often chosen for treatment. However, traditional surgical resection has high risks of complications and affects the quality of life of patients. We report a case of pulmonary sequestration combined with recurrent hemoptysis treated by interventional embolization. The examination showed a 2.0 cm abnormal blood supply artery originating from the thoracic aorta in the left lower lung. Interventional embolization was performed. One month after the operation, the embolization was satisfactory and the hemoptysis disappeared. During the 3-month follow-up, the condition was stable. Interventional treatment is minimally invasive and has a fast recovery rate. The efficacy is superior to traditional surgery and is the preferred treatment option for PS combined with hemoptysis. It is worthy of clinical promotion.
