Intralobar pulmonary sequestration is a rare congenital malformation characterized by the presence of dysplastic lung that does not communicate with the tracheobronchial tree, and has aberrant systemic arterial supply. While most are asymptomatic, they rarely can present with hemoptysis, which has been traditionally managed with surgical resection of the sequestration. We report a case of an 18-year-old male who presented with acute large-volume hemoptysis on a background of recurrent minor episodes of hemoptysis, due to intralobar sequestration. He was successfully treated with transarterial embolization with a combination of polyvinyl alcohol (PVA) particles, gelfoam and coils. Transarterial embolization can be effective in managing emergent hemoptysis from pulmonary sequestration.
叶内型肺隔离症是一种罕见的先天性畸形，其特征为存在发育异常的肺组织，该肺组织与气管支气管树不相通，且有异常的体循环动脉供血。虽然大多数患者无症状，但少数患者可出现咯血，传统上通过手术切除隔离肺来治疗。我们报告一例18岁男性患者，因叶内型肺隔离症，在反复少量咯血的基础上出现急性大量咯血。他通过使用聚乙烯醇（PVA）颗粒、明胶海绵和弹簧圈联合进行经动脉栓塞治疗而获成功。经动脉栓塞在处理肺隔离症所致的急性咯血方面可能有效。
