말기 폐기종 환자의 치료에 있어서 폐이식술은 최근 5년 생존율의 향상으로 점점 확대외어 가는 추세이다. 또한 이식폐의 부족으로 일측 폐이식술이나 이형 혈액형에서의 폐이식술의 시행이 늘고 있는 추세이다. 이형 혈액형에서의 폐이식은 술후 적절한 면역 억제제의 투여로 동형 혈액형에서의 폐이식술에서와 마찬가지로 좋은 결과를 보이고 있다. 저자들은 말기 폐기종으로 호흡 곤란이 심해져 가는 35세 A형 여자 환자에 O형 남자 환자의 좌측 폐를 이식하였다. 술후 면역 억제를 위해 3제 치료(싸이클로스포린, 아자씨오프린, 프레드니졸론)를 실행하였고 수술 중에 항CD3항체(OKT3)를 1회 투여하여 이식 거부 반응을 억제할 수 있었다. 환자는 술후 특별한 문제 없이 18일째에 퇴원할 수 있었다.

Lung transplantation is the choice of treatment for selected patients with end-stage pulmonary disease. However, retransplantation of the lung due to primary graft failure carries a high risk of morbidity and mortality. This is a case of a 52 year old male with emphysema who continuously needed a ventilator care and a tracheostomy. He underwent a left single lung transplantation but were not able to wean from the ventilator due to primary graft failure, and therefore we decided to do a retransplantation. Bilateral sequential single lung transplantation was performed under the cardiopulmonary bypass. The patient recovered quite well and was discharged and fully active with his work. Retransplantation although it carries a high risk, is a very effective treatment in patients with primary graft failure.

Eisenmenger's syndrome is the disease of right to left shunt developing from the increased pulmonary vascular resistance caused by excessive pulmonary blood flow in patients with abnormal connections of systemic to pulmonary blood passage. The heart-lung transplantation was the only curative method in early transplantation period, but good results after bilateral lung transplantation have been reported as the fact that right heart function improved by only lung transplantation. We successfully carried out bilateral sequential single lung transplantation in a 34-year-old female patient with Eisenmenger's syndrome with large PDA. We report this case with a brief review of the literature.

A 43 year-old female, who underwent bilateral lung transplantation for Eisenmenger syndrome 10 years previously, visited our hospital complaining of progressive severe dyspnea. She was diagnosed as having. bronchiolitis obliterans syndrome, which was presumably caused by chronic graft rejection following lung transplantation. Due to the aggravated dyspnea despite medical treatment, she required ventilator care and then she underwent lung retransplantation. We report here on a case of lung retransplantation for treating chronic graft rejection following the previous lung transplantation for the first time in Korea.

Lymphangioleiomyomatosis (LAM) is a rare disease in women of childbearing ages that eventually leads to respiratory failure. Lung transplantation is the only conclusive therapeutic modality in end-stage LAM. While single-lung transplantation is the preferred operation, the graft failure or recurrence of LAM was reported. We performed a single lung transplantation on a 36-year-old woman suffering from respiratory failure due to lymphangioleiomyomatosis. After a 1-year follow up, the patient was readmitted because of graft failure with collapsed transplanted lung. The lung volume reduction surgery (LVRS), tracheostomy and ventilator care were performed. However, neither the medical nor surgical treatment had any effect. Subsequently, we performed a contralateral single lung re-transplantation and had a good postoperative results.

Although lung transplantation has been accepted as the most effective treatment for end-stage pulmonary emphysema, it is not only very hard to find a donor but also to obtain a relatively healthy lung. Furthermore, it is more difficult to match the size of the allograft, considering the height, the weight, and the size of the thoracic cage. The single lung transplatations for the end-stage emphysema have been more commonly performed than bilateral lung transplantation due to the shortage of the donors and the long-term survival rate of the single lung transplantations has shown no reasonable difference compared with that of the bilateral lung transplantationh. Recently, the functional criteria based on a comparison of predicted TLCs(Total Lung Capacities) of the donor and recipient according to height, sex and age, have been accepted at a more suitable.

Background: Lung transplantation is a definitive therapy for a variety of end stage lung diseases. Since 1996, we have performed thirteen cases of lung transplantation including two retransplantations, and we analyzed the outcomes, complications, and survivals of these patients. Material and Method: We retrospectively analyzed the medical records of thirteen cases from July, 1996 to July, 2005. Result: During the period, 11 patients had undergone 43 lung and heart-lung transplantations, and two patients had retransplantation due to allograft failure. Mean age of recipients were $45.2{\pm}10.7$ years(range, $25{\sim}59$). Early complications were bleeding, reperfusion injury, and infection and late complications were mainly infection and post-transplantation lymphoproliferative disease. Excluding the operative mortality, the mean survival period was 16.5 months($2{\sim}60$ months). Two retransplantations had been performed 2 weeks and 13 months after single lung transplantations. Conclusion: In order to achieve long term survival, early detection of complications and proper treatment in addition to surgical skills are necessary, and these efforts can promote better lung transplantation programs in the near future.

The Iymphoproliferative disease after the organ transplantation is more commonly seen with the increase according to the increasing number of the organ transplantations and it occurs more frequently in the cases of heart and lung transplantations that needs more aggressive immunosuppression. It demands urgent evaluation and management because of poor prognosis. We transplanted left lung of a man to the woman who suffered from severe dyspnea due to terminal pulmonary emphysema in discrepancy of ABO blood type. Postoperatively, We used triple regimen immunotherapy(cyclosporin, azathioprine, prednisolone) and followed up in the out patient clinic. During the follow up, we found abnormal mass lesion on the transplanted lung and performed gun biopsy. We confirmed malignant lymphoma on the pathollgic examination and two cycled chemotherapy was given after reducing dose of immunosupression. The patient died of sudden onset of pulmonary edema of the transplanted lung.

Artificial lung support may be necessary in various conditions during the performance of bilateral lung transplantation, and cardiopulmonary bypass (CPB) has usually been used. Yet using the conventional CPB techniques may increase risk of bleeding and early allograft dysfunction due to the large dosages of heparin and the complement activation. Extracorporeal membrane oxygenation (ECMO) is able to support gas exchange and maintain the hemodynamics without administering high-dose heparin for anticoagulation. We performed sequential bilateral lung transplantation with ECMO support. ECMO is a valuable tool when performing lung transplantation and it has the potential to replace CPB.

Background. Limited ischemic tolerance of the lung has remained one of the factors that limits the expansion of pulmonary transplantation as a treatment for end-stage pulmonary disease. Numerous studies on safe long term preservation for lung transplantation has been performed for the purpose of developing ideal preservation solution with extracellular type or intracellular type solutions. In this. study, we examined the efficacy of L DG solution in lung preservation longer than 20 hours by comparison with modified Euro-Collins solution. Iwethods. Thirty-(our adult mongrel dogs were divided into two groups. Donor lungs were flushed with LPDG solution(n=9) or modified Euro-Collins(MEC) solution(n=8) and stored for 24 hours at 1$0^{\circ}C$. All donor lungs were perfused through the pulmonary arteries with solutions containing prostaglandin El and verapamil. Left canine lung allotransplantations wereperformed. Assessment(hemodynamic indices and arterial blood gas analysis) of left implanted lung was made by occluding the right pulmonary artery for ten minutes using pulmonary artery Cuff. Assessment was repeated at the interval of 30 minutes, one hour, and two hours later after reperfusion and then chest X-ray, computed tomogram and lung perfusion scan were obtained. In survival dogs follow-up studies were done with assessment with chest X-ray, computed tomogram of the chest and lung perfusion scan on 7th day postoperatively. After preservation above 20 hours, pathological examinations for ultrastructural findings on right lung were performed in each group. Results. With respect to arterial oxygen tension, LPDG group was superior to MEC but there was no statistical significance for 2 hours after reperfusion. Mean pulmonary artery pressure was less increased(p < 0.05) and cardiac output higher(p <0.05) than MEC group until 2 hours after reperfusion. After 2 hours of reperfusion, both groups showed transplanted lung function deteriorated gradually. Perfusion scan of the transplanted lung in LPDG group showed better perfusion rate in immediate post-reperfusion, 3 days and 7 days later respectively but there was no statistical significance and corelation with PaO2 and computed tomoRravhic views. In scanning electron microscopy of pulmonary artery after preservation, LPDG group relatively shows less irregular protrusion of the inner surface of endothelial cell of poulmonary artery than MEC group. Conclusions, e concluded that LPDG solution can offer safe lung preservation above 20 hours with adequate immunosuppressive therapy and prevention of the infection.
