The bronchopulmonary sequestration is a region of the lung parenchyma that has an incomplete or no connection with the airways and is supplied by an aberrant artery arising from the aorta or one of its branches. The anatomy of the supplying artery is very important during operation. A case of pulmonary sequestration supplied with the left gastric artery is presented. The patient was 61 years old male and had hemoptysis. The chest CT showed cystic bronchiectasis in the left lower lung with few air-fluid level. Also, in aortogram, arterial supply was The aortogram also showed arterial supply coming from the left gastric artery of abdominal aorta branches. Left lower lobectomy and abnormal arterial ligation were performed. 폐격리증은 비정상적으로 발생한 폐조직과 이상동맥에 의해 형성된 선천성 질환으로 비교적 드문질환이다. 폐격리증에서 이상동맥의 해부학적 위치는 수술합병증의 발생에 매우 중요하다. 저자들은 객혈을 주소로 내원한 61세 남자환자에서 대동맥촬영상 좌위동맥에서 기시하는 비비꼬인 형태의 이상동맥에 의해 공급받는 폐격리증 1예를 경험하였기에 보고하는 바이다.

The objectives of this study were to prepare a new artificial eardrum patch using water-insoluble chitosan for healing the tympanic membrane perforations and to investigate biomechanical properties and cyotoxicity of the chitosan patch scaffold (CPS). Tensile strength and elongation at the rupture point of CPSs were 2.49-74.05 MPa and 0.11-107.06%, respectively. As the biomechanical properties of CPSs varied with the concentration of chitosan and glycerol, the proper conditions for the CPS were found out. SEM analysis showed very smooth and uniform surface of CPSs without pores at x1000. The result of MTT test showed that CPSs had no cytotoxicity.
