We have performed 28 single lung transplantation in mongrel dogs transplanting the left lung exclusively from November 1989 to September 1991, in the department of thoracic surgery of Seoul National University Hospital. In the donor dogs, the main pulmonary artery was divided proximal to its bifurcation, and the left atrium was incised freeing the left veins with a generous atrial cuff. We used cold saline in the first 7 transplantations and Euro-Collins or modified Euro-Collins solution in the remaining 17 transplantations as a lung preservatives. The bronchus was divided at two cartilage rings proximal to the upper lobe bronchus take off. In the recipient procedure, we used a Fogarty catheter as a bronchus block. Left atrial anastomosis was performed first using 5-O prolene and the pulmonary artery was anastomosed using 6-O prolene. The bronchus was anastomosed next with 4-O vicryl interruptedly and covered with a greater omentum which had been prepared previously. All dogs received cyclosporin A and azathioprine as immunosuppressants and were divided into two group. In the 10 Group I dogs, they survived within 6 days, mean survival time was 66.8$\pm$53.4 hours. In remainder 14 Group lI dogs, they survived above 6 days, mean survival time was 9. 5$\pm$5.6 days. The cause of death were as follows: 2 cases of sacrifice, 2 cases of respiratory insufficiency during operation, 2 cases of arrhythmia immediate postoperatively, 2 cases of bleeding, others in Group I, and 6 cases of sacrifice, 4 cases of sepsis, 3 cases of bleeding, others in Group lI. Results of bronchoscopic findings were obstruction above 50% in 12 cases of 16 performance cases within 5th day. Early chest radiologic haziness were showed, and total lung perfusion defect was frequently showed in both group within 7th day. Main autopsy findings were left atrial and pulmonary arterial thrombi and bronchial obstruction The major histologic findings of Group I were pleural exudate, hemorrhagic infarct, pulmonary congestion, and interesting histologic findings of Group II were 3 cases of perivascular or peribronchial lymphocyte infiltration, 3 cases of hemorrhage infarct, 2 cases of interstitial pneumonitis. The structual change of bronchioles, suggesting bronchiolitis obliterans was not observed due to improper preparation of proximal pulmonary tissue and short term survival times.

폐경색은 폐동맥의 폐색으로 인해 발생하며 기관지내 세균오염에 의해 폐감염이 흔하게 속발하며 이는 폐농양, 농흉 그리고 기관지 흉막루 등을 일으켜 결국 패혈증에 이르게 할 수 있다. 이러한 이유로 조기 진단이 중요하며 감염 조절을 위해 폐절제 등을 조기에 고려해야 한다. 67세 남자가 호흡곤란을 주소로 응급실에 내원하였다. 흉부 전산화 단층 촬영에서 좌하엽에 침윤성 병변과 소량의 흉수 그리고 늑막 비후가 관찰되었다. 폐색전은 하엽 폐동맥에서 상엽 폐동맥까지 자라나 있었다. 출혈성 경색이 완연한 좌하엽은 절제되었고 좌주폐동맥을 열어 나머지 폐색전을 제거하였다. 수술 후 15개월간 추적 관찰하고 있으며 폐색전이나 폐경색의 재발은 보이지 않았다.

Concomitant rupture of the subclavian vessels and the left main bronchus caused by blunt trauma is a serious condition. Moreover, the diagnosis of a tracheobronchial injury with rupture of the subclavian vessels can be difficult. This report describes the case of a 33-year-old man who suffered from blunt trauma that resulted in the rupture of the left subclavian artery and vein. The patient underwent an operation for vascular control. O n postoperative day 3, the left main bronchus was found to be transected on a computed tomography scan and bronchoscopy. The transected bronchus was anastomosed in an end-to-end fashion. He recovered without any notable problems. Although the bronchial injury was not detected early, this case of concomitant rupture of the great vessels and the airway was successfully treated after applying extracorporeal membrane oxygenation.

The bronchogenic cysts result from an abnormal budding or branching of the tracheo-bronchial tree from the primitive foregut. Bronchogenic cysts may be pulmonary or mediastinal. The most common location for a mediastinal bronchogenic cyst is in relation to the carina. They are usually solitary. They usually are thin walled and contain fluid that is most often clear. The cyst is lined by ciliated columnar epithelium. The bronchogenic cyst i~ usually asymptomatic. They can cause pressure symptoms. When they become infected, symptoms do occur. We report 3 cases of bronchogenic cysts experienced at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. Case I, a man of 20 year-old, had a cyst at the site between aortic arch and left pulmonary artery. He complained cough and dyspnea. The cyst wasn`t communicated with tracheobronchial tree. Case II was 55-year-old male who had had hemoptysis. A huge cyst was located within the lower lobe of left lung and removed by pulmonary lobectomy. There were not any symptoms in Case III that was 6-year old girl. That cyst was located just next to the right main bronchus.

연구배경 : 대량 객혈은 내과적 혹은 외과적 치료로도 사망율이 매우 높은 임상증상이다. 대량 객혈은 높은 기관지 동맥 혹은 비기관지성 전신동맥에서 출혈된다고 알려져 있으므로, 최근 상기 혈관들을 색전시키는 것이 치료방법으로 되고 있으나 초기 색전후 일부에서 객혈이 재발되는 것이 문제로 되어 있다. 이에 저자들은 대량출혈환자에서 동맥색전을 하여 즉각적인 지혈정도를 알아보고, 즉시 지혈된 후 객혈이 재발되는 환자들의 임상소견 및 초기 동맥촬영소견을 조사하여 보았다. 방법 : 1988년 1월부터 1991년 7월까지 전부 21명의 환자에서 대량 객혈로 동맥색전술을 시행하였다. 환자 모두에서 대퇴통맥으로 경피하 삽관술을 하여 기관지동맥외에도 비기관지 전신동맥에 혈관촬영을 시행한 후, 병변부위의 혈관에 gelfoam pieces로 색전을 실시하였다. 이후 환자들을 추적관찰하면서 동맥색전술의 효과를 평가하였다. 결과 : 처음 동맥색전후 21명의 전환자에서 즉시 지혈은 성공하였다. 9명의 환자에서 출혈이 재발되었으며, 12예의 환자들에서는 객혈의 재발은 없었다. 합병증으로는 발열, 흉통, 기침, 배뇨 장애, 장마비, 하지마비 및 비장경색증등이 있었으며, 9명의 환자에서는 별 증상을 호소하지 않았다. 출혈이 재발된 환자중, 2명은 대량객혈로 사망하였고, 2명은 폐절제술을 시행받았으며, 4명은 매번 객혈이 재발시마다 반복적인 동맥색전술 혹은 내과적 보존치료를 받고 있다. 결론 : 재출혈의 가능성이 있기는 하지만, 동맥색전술은 대량 객혈환자에서 출혈을 비교적 빠르고 안전하게 멈출 수 있는 치료법이다. 또 수술적 치료가 불가능한 폐질환 환자에서 객혈이 재발시마다, 반복 시행하는 동맥색전술은 일단 급한 출혈을 막고 생명을 연장시키는 데에 도움을 주리라 사료된다.

Bronchoarterial (BA) ratio is a commonly used criterion to define airway dilatation despite the lack of normative human and animals. The objective of our study was to compare the range of normal bronchial to accompanying arterial diameter ratio with previous reports on CT scan of the thorax in dogs and assess influence anesthetics on BA ratio in dogs. Dogs undergoing multidetector CT scan of the chest for nonpulmonary conditions at a single center were prospectively identified. High-resolution reconstruction was performed on those included and both airway lumen and vessel diameters were measured in the lobar bronchi of the left cranial (cranial and caudal parts), right cranial, right middle, left caudal, and right caudal lung lobes. Eight dog were included; Mean of the mean BA ratios was $1.43{\pm}0.24$ (95% CI = 1.36 - 1.50) in inhalation anesthetic group. In propofol group, the mean of the mean BA ratios was $1.13{\pm}0.29$ (95% CI = 1.04 - 1.22). In medetomidine group, the mean of the mean BA ratios was $0.89{\pm}0.19$ (95% CI = 0.83 - 0.95). Comparing individual lobes within anesthetic category, there was no signicant difference in mean BA ratio between lung lobes or between dog according to inhalation, propofol, and medetomidine group (P = 0.630, P = 0.878, and P = 0.508, respectively). The BA ratio in these clinically normal dogs was consistent and may be a useful tool in evaluating for bronchiectasis on CT images. However, some different criteria for bronchiectasis were applied by the anesthetic methods.

The most common symptom associated with an pulmonary aspergilloma is hemoptysis, with estimates of frequency ranging from 50 to 85 percent of patients. Hemoptysis may be infrequent and minimal in amount or it may be severe with a fatal outcome. The major options available for the treatment of pulmonary aspergilloma include sugical resection of the lesion, a number of medical therapies, or simple observation of the patient for a time. Surgery is the treatment of choice but it is not feasible in some patients who have diffuse or advanced pulmonary disease that makes them poor candidates for thoracotomy. As an alternative to it, some categories of therapy including bronchial artery embolization and parenteral or endobronchial administration of antifungal drugs were tried without remarkable success. But percutaneous instillation of intracavitary amphotericin B for symptomatic aspergilloma has been reported with better result. The authors present a case of percutaneous intracavitary instillation of amphotericin B for the treatment of pulmonary aspergilloma and its successful result for the repetitive hemoptysis.

Prolapse of the aortic valve is the main cause of insufficiency of the aortic valve as a complication of ventricular septal defect. Aortic insufficiency gets worse by the progress of prolapse of aortic valve due to lack of support of the valve and the hemodynamic effect of blood flow through the ventricular septal defect. This produces typical clinical picture, that may be serious and threatening when it is untreated. Type and timing for the surgical treatment of the ventricular septal defect with aortic insufficiency is considered. Among 113 ventricular septal defect, 9 patients of ventricular septal defect with associated aortic insufficiency were experienced from June. 1983 to June 1988 at the Department of Thoracic and Cardiovascular Surgery, Chon-Buk University Hospital. Male was 6 patients and female was 3 patients. Ages were from 7 years to 24years. 5 patients were from 10 to 19 years age. 3 patients were below 10 years age. The ratio of pulmonary blood flow to systemic f low [Qp/Qs] was 1.53 and in pulmonary vascular resistance, normal or slight increase was 7 patients, moderate 1 patient, and severe 1 patient. Ventricular septal defect was subpulmonic in 5 patients and infracristal in 4 patients. Prolapse of right coronary cusp was 7 patients, right and non coronary cusp 1 patient and non coronary cusp 1 patient. Teflon patch closure of ventricular septal defect was undertaken in 3 patients and primary closure in 1 patient. Among the 4 patients of defect closure alone, one patient performed valve replacement 7 months later due to progressive regurgitation and cardiac failure and the result was good. The other 3 patients were good result. Closure of ventricular septal defect and aortic valvuloplasty performed in 4 patients. 2 patients of these required valve replacement for the sudden intractable cardiac failure and died due to low cardiac output. The cause of intractable cardiac failure was tearing of repaired valve at the fixed site. The other 2 patients were good result. Closure of ventricular septal defect and valve replacement performed in 1 patient with good result.
