  • Bronchopulmonary sequestration is a congenital malformation characterized by a cystic portion of the lung that derives its arterial blood supply through anomalous aberrant vessel directly of the systemic circulation. An aberrant systemic vessel supplying the lung was reported by Huber in 1777. Although this lesion is uncommon disorder, there are several reports on operative death caused by exanguinating hemorrhage from the aberrant arteries to the bronchopulmonary sequestration to that it has received a great deal of attention. Two type of bronchopulmonary sequestration have been identified: Intralobar pulmonary sequestration is usually contained within the visceral pleura of a pulmonary lobe and its venous drainage to the pulmonary venous system. Extrapulmonary sequestration is usually within the pleural sheath its own and its vasculature drains into the azygos or hemiazygos system. we presented one case of intralobar pulmonary sequestration which led to motor paralysis, chylothorax and hemorrhage that are consequent on postoperative complication.

  • A total of 21 patients with pulmonary sequestration who had undergone surgical treatment were reviewed at the department of thoracic and cardiovascular surgery of catholic university medical college from May 1983 through May 1993. The pulmonary sequestration was intralobar in 19 patients, and extralobar in 2 patients. There were 17 woman and 4 man ranging of age from 17 months to 48 years with a mean age of 21.3 years. Clinical manifestations were varied from no symptom[3 cases to recurrent pneumonia[15 cases , and hemoptysis[3 cases . Preoperative diagnosis was correct in only 6 cases[29% of the 21 patients of pulmonary sequestration . The left lower lobe[11 cases is most often affected in intralobar sequestration. The aberrant artery in intralobar sequestration originated in 13 cases[68% of 19 cases from descending aorta. 15 of the 19 patients of intralobar type underwent lobectomy. The extralobar sequestration[2 cases were simply excised. There was no mortality and no complication.

  • This is a case report of extralobar pulmonary sequestration with bronchogenic cyst located in aorto-pulmonary window area of left thorax in a 17 months old male patient. In this case, a bronchogenic cyst was presented immediately adjacent to the extralobar pulmonary sequestration. Communication between the extralobar pulmonary sequestration and bronchogenic cyst was not seen grossly or microscopically. The lesion was simply excised and the postoperatively course was uneventful.

  • This study estimated the carbon sequestration from urban green spaces in Ansan City using environmental spatial information. We examined study results of carbon sequestration from existing urban green spaces, using a land cover map (level 3). In particular, the carbon sequestration of trees by land use and the IPCC Global default value were linked with the land cover map level 3. Domestic research showed that carbon storage in urban green spaces in Ansan City was 17,927.2 tC, and the annual carbon sequestration was calculated as 2,680.5 tC/yr. On the other hand, applying the IPCC Global Default value resulted in annual carbon sequestration of 5,287.8 tC/yr, which was 2,607.3 tC/yr more that the domestic research value. This resulted from difference in detailed methodologies such as background data, sample size for on-site investigation, and measurement of tree species. The study presented a consistent assessment method to assess the sequestration of carbon from municipal urban green spaces. Furthermore, we provided basic data that could be useful in urban green space policies.

  • Objectives : The purpose of this study is to report the image changes of two cases of Lumbar intervertebral Disc Sequestration after oriental medical treatment. Methods : We examined 2 patients with Lumbar intervertebral Disc Sequestration who showed changes on MRI images before/after the treatment. And we assessed clinical symptoms by using numeric rating scale(NRS) and straight leg raising test(SLRT). Results & Conclusions : In this study, the first MRI examination of Lumbar intervertebral Disc Sequestration patients was performed at the first visit and re-examination of MRI was done after treatment. In each case, the size of the disc sequestration was considerably reduced in MRI image. And both patients represented effective improvment in NRS score and SLRT test angle.

  • Pulmonary sequestration Is an unusual congenital malformation characterized by the presence of nonfunctioning lung tissue which usually has no communication with the normal bronchial tree and which receives its blood supply from an anomalous systemic artery instead of a pulmonary arterial branch. Two forms of pulmonary sequestration occur: Intralobar sequestration, in which the abnormal pulmonary tissue is incorporated within the normal lung and shares a common covering of visceral pleura, and extralobar sequestration, in which the abnormal pulmonary tissue is separated from the normal lung and has its own pleural investment. Since 1970, five cases of pulmonary sequestration were operated at the Department of Thoracic and Cardiovascular Surgery, College of Medicine, Seoul National University. 1. Among five cues, one was male and the others were female. 2. All were intralobar type and involved left lower lobe. 3. There was no operative mortality following left lower lobectomy and ligation of the aberrant artery.

  • Elevated carbohydrate antigen (CA) 19-9 can indicate malignancies of the gastrointestinal, pancreatic, and biliary tracts, and be found in a pulmonary sequestration. A 30-year-old man visited Seoul National University Bundang Hospital due to elevated CA 19-9 levels, representing pulmonary sequestration of the bilateral lower lobes, which were connected with each other. We performed left lower lobectomy and division of the systemic arteries. After operation, CA 19-9 levels decreased to normal range, even though a small amount of sequestrated lung remained in the right lower lobe. It is not uncommon that presence of pulmonary sequestration might elevate serum CA 19-9 levels; however, horseshoe type bilateral pulmonary sequestration is very rare.

  • 본 연구의 목적은 KOMPSAT-2 영상을 이용하여 대상지 내 주요 수종의 이산화탄소 흡수량을 추정하는 것이다. 우선, KOMPSAT-2 영상을 분할영상분류방법으로 산림내 수종을 임상단위로 분류하였다. 분류된 임상의 평균 수관직경을 추정한 후, 이를 각 수종의 면적에 대비시켜 수종별 본수를 추정하였다. 평균 흉고직경은 지상조사를 통해 유도된 수관직경과 흉고직경의 관계식을 이용하여 추정하였다. 이와 같이 추정된 수종별 흉고직경과 본수를 기존의 바이오매스 추정식에 대입하여 수종별 바이오매스를 추정하였다. 바이오매스에 '기후변화에 관한 정부간 패널(IPCC)'의 가이드라인에 따른 계수를 적용하여 임상단위의 이산화탄소 흡수량을 추정했다. 본 연구의 임상단위 수종별 이산화탄소 흡수량 추정 접근방식은 향후, 표본점 단위의 이산화탄소 흡수량을 임상단위 이산화탄소 흡수량으로 확장시키는데 활용될 수 있다.

  • Congenital thoracic malformations such as intra- and extra-pulmonary sequestration, cystic adenomatoid malformation, congenital pulmonary airway malformation, malinosculation, bronchogenic cyst, reduplication cyst, and foregut cyst are frequently detected on routine prenatal ultrasound. There are some controversies about treatment for postnatally persistent pulmonary sequestration. Some authors recommend expectant long term follow up but most authors advocate elective surgical excision because of complication such as respiratory distress, infection, intrathoracic bleeding, haemoptysis, cardiac failure, and potential risk of malignancy. We experienced 2 cases of prenatally diagnosed extrapulmonary sequestration which were located in the subdiaphragmatic retroperitoneum. Resections were performed at 2 months and 4 months of age using intraabdominal approach. There were no complications. In conclusion, if the prenatally diagnosed extrapulmonary sequestration remained postnatally, early operation might reduce morbidity related to extrapulmonary sequestration and parental anxiety without any postoperative complication.

  • The pulmonary sequestration is an uncommon congenital anomaly characterized by the presence of nonfunctioning lung tissue supplied by aberrant artery from the aorta or its branches and usually has no communication with the normal bronchial tree. The patient was 35 year old female and had no specific complaints. The lung mass was found incidentally and was continned to be intralobar pulmonary sequestration by aotography whitch showed aberrant blood supply from thoracic aorta at the T. vertebra level. The right lower lobectomy was done.
