Pulmonary sequestration (PS) is a rare congenital malformation, even more when its arterial supply is a coronary artery. We present a case of a 68-year-old man admitted in the emergency room with an acute coronary syndrome and no evidence of significant coronary disease. Instead, he had an abnormal branch from the circumflex coronary artery nourishing a mass in the left lower pulmonary lobe. A coronary steal phenomenon was proposed to explain the clinical presentation. An anterior left thoracotomy with ligation of the abnormal branch and atypical resection of the lung segment comprising the sequestration was performed.
肺隔离症（PS）是一种罕见的先天性畸形，当其动脉供血为冠状动脉时则更为罕见。我们报告一例68岁男性患者，因急性冠状动脉综合征入住急诊室，并无明显冠状动脉疾病的证据。相反，他的左旋支冠状动脉有一异常分支，为左下肺叶的一个肿块供血。提出冠状动脉窃血现象来解释其临床表现。实施了左前开胸手术，结扎异常分支，并对包含隔离肺的肺段进行非典型切除。
