실험동물에서의 폐이식수술에서 비침습성 흉부전산화 단층 촬영을 이용하여 이식폐의 기능평가지표의 가치를 분석해 보고자 한국산 잡종견을 이용하여 좌측일측폐이식술후 7일 이상 생존시킨 성견을 대상으로 급성거부반응 및 허혈-재관류손상, 감염 등의 소견을 병리조직소견과 함께 관찰하였다. 실험견은 총 22마리에서 11마리씩 공급견과 수용견으로 나누어 시행하였다. 공급견의 심폐블록보존은 Modified Euro-Collins (MEC) 용액과 low potassium dextran glucose(UDG)용액을 이용하여 $10^{\circ}C에서$ 20시간 (1례에서 4시간 보존) 이상 냉장보관하였다 폐이식술후, 흉부 X-선과 연속적인 컴퓨터단층촬영을 수술 직후와 술후 3일 및 7일째 각각 시행하였다. 11례의 이식견 중 2례에서 급성거부반응을 보였고 전산화단층촬영상 폐침윤정도가 수술 직후 중등도였다가 수술 3일째 확장성으로 변하였다. 결론적으로 일측 폐이식성견의 실험적인 모델에서 이식폐장의 기능평가지표로서 컴퓨터단층촬영을 이용 하며 다른 평가지표와 유사한 소견을 얻었고 폐의 감염과 거부 반응의 구별은 단층촬영의 음영의 비교만으 로 감별이 용이하지 않았으며 다른 평가지표 및 폐생검\ulcorner 확인으로 조기거부반응의 진단 가능성을 평가할 수 있었다.

Kartagener syndrome (KS) is a rare disease with an incidence of 1 in 20,000 to 30,000 births. There is no cure for KS, and conservative medical treatments are used to relieve symptoms and prevent disease progression. Lung transplantation (LT) is the only treatment option for end-stage KS. Since patients with KS have anatomical abnormalities such as situs inversus totalis, which often require surgery to correct, most reports are related to surgical techniques. Reports about morphological adaptations and changes in transplanted lung structure after LT in patients with KS are rare. We performed LT in a patient with KS and observed morphological adaptation of the lungs for 6 months on chest computed tomography using a quantitative evaluation tool (Chest Image Platform; Harvard University Disability Resources, Cambridge, MA, USA).

이식 후 발생하는 임파구 증식성 질환은 장기 이식의 예가 늘어나면서 증가하는 추세이며 폐 ,심장 이식과 같이 면역 억제 요법의 강도가 심할수록 그 발생률이 높아진다. 특히 임파구 증식성 질환 중 악성 임파종은 치료가 어렵고 예후가 좋지 않아 신속한 진단 및 치료가 필요하다. 본원에서는 1999년 11월 말기 폐기종으로 호흡 곤란이 심해져 가는 37세 A형 여자 환자에 0형 남자 환자의 좌측 폐를 이식하였다. 폐 이식 수술 후 면역 억제를 위해 3제 치료(싸이클로스포린, 아자씨오프런, 프레드니졸론)를 시행하였고, 환자는 이식 후 특별한 문제없이 외래 추적 관찰 중 정기적으로 시행한 가슴 컴퓨터 단층 촬영 상 이식 폐에 비정상적 종괴가 보여 2001년 2월 gun biopsy 시행 후 악성 임파종으로 진단을 받았으며 면역 억제제 감량 후 항암 화학요법 2회 시행하고 경과 관찰 중 갑자기 발생한 이식 폐부종으로 사망하였다.

We have performed 14 single lung transplantation in mongrel dogs transplanting the left lung exclusively from December 1989 to January 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 transplantation[group I ] and a Euro Collins solution in the remaining 7 transplantations[group II ] 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 - 0 prolene and the pulmonary artery was anastomosed using 6 - 0 prolene. The bronchus was anastomosed next with 4 - 0 Vicryl interruptly and covered with a greater omentum which had been prepared previously. In group I the three dogs died at eleven hours, 5 days, and 14 days, postoperatively and the remaining four doings were killed at 5 days, 5 days, 6 days, and 12 days, respectively. In group II the two dogs died during the operation, one dog died at 6 hours, two dogs died at 6 days postoperatively. Two dogs were killed at 5 days, and 7 days. No significant difference was noted between the two groups in survival time, lung infiltration of transplanted lungs, and perfusion defects in perfusion lung scans. Of the 8 dogs which died naturally, the causes of death were as follows: 2 cases of sepsis, 2 cases of ventricular fibrillations, 2 cases of malnutrition, and 2 cases of respiratory failures.

Lung retransplantation (LRT) involves a second or subsequent lung transplant (LT) in a patient whose first transplanted graft has failed. LRT is the only treatment option for irreversible lung allograft failure caused by acute graft failure, chronic lung allograft dysfunction, or postoperative complications of bronchial anastomosis. Prehabilitation (rehabilitation before LT), while patients are on the waiting list, is recognized as an essential component of the therapeutic regimen and should be offered throughout the waiting period from the moment of listing until transplantation. LRT is particularly fraught with challenges, and prehabilitation to reduce frailty is one of the few opportunities to address modifiable risk factors (such as functional and motor impairments) in a patient population in which there is clearly room to improve outcomes. Although rehabilitative outcomes and quality of life in patients receiving or awaiting LT have gained increased interest, there is a paucity of data on rehabilitation in patients undergoing LRT. Frailty is one of the few modifiable risk factors of retransplantation that is potentially preventable. As such, it is imperative that professionals involved in the field of retransplantation conduct research specifically exploring rehabilitative techniques and outcomes of value for patients receiving LRT, because this area remains unexplored.

A 58-year-old man, incapable of maintaining oxygen saturation with mechanical ventilation, was admitted to our hospital for veno-venous extracorporeal membrane oxygenation (ECMO) treatment. He was diagnosed with acute respiratory distress syndrome (ARDS) due to influenza A pneumonia. His condition stabilized with antibiotics and steroid administration, but weaning from ECMO failed due to post-infectious pulmonary sequelae. On day 84 after admission, he underwent bilateral lung transplantation. In the postoperative phase, he did not regain consciousness even after discontinuation of sedatives for 3 days. However, spontaneous pupillary reflex and eye movements were preserved, while communication and upper and lower limb movements were affected. The nerve conduction study was diagnostic of Guillain-Barré syndrome. He was managed with intravenous immunoglobulins and plasmapheresis. Mild recovery of the facial muscles was seen, but he died 24 days post-surgery due to progressive ARDS and sepsis.

Herein, we report a case of lung transplantation in a patient with profound preoperative hypercapnia, focusing on the cardiopulmonary bypass strategy used for brain perfusion during the operation. We applied the pH-stat method for acid-base regulation, and thereby achieved the desired outcome without any neurologic deficit.

확장성 심근병증과 말기 심부전으로 진단된 40세 남자환자가 1997년 7월 좌심실 축소술(partial left ventriculectomy)을 시행하고 18개월 후 1999년 1월 심장 이식술을 시행하였다 좌심실 축소술 시행후 3개월에 시행한 심초음파 소견상 좌심실 구출율은 26%에서 42.6%로 증가하였고, 확장기 좌심실크기는 71 mm에서 45mm로 감소하여 심초음파로 측정한 심박출량 및 심박출지수는 각각 3.95 L/min, 2.28 L/min/m$^2$이었다. 술 후 11개월뒤 심초음파상 좌심실 크기가 56/51 mm(확장기/수축기 직경)로 증가하고 좌심실 구출율은 17%로 감소하여 약물을 더 증량하고 18개월째에 공여심장이 제공되어 심장이식을 시행하였다. 1, 3, 6개월만에 3회 시행한 심근 조직검사상 ISHLT(International Society of Heart and Lung Transplantation) 분류상 la로 판정됐고 현재까지 거부반응으로 인한 치료는 필요하지 않았다. 말기 심부전을 동반한 확장성 심근병증 환자에서 심장 이식을 기다리는 동안 좌심실 축소술이 성공적인 교량역할을 했기에 이를 보고하는 바이다.

Since the initial International Society of Heart Lung Transplantation registry was published in 1982, the number of pediatric heart transplantations has increased markedly, reaching a steady state of 500-550 transplantation annually and occupying up to 10% of total heart transplantations. Heart transplantation is considered an established therapeutic option for patients with end-stage heart disease. The long-term outcomes of pediatric heart transplantations were comparable to those of adults. Issues affecting long-term outcomes include acute cellular rejection, antibody-mediated rejection, cardiac allograft vasculopathy, infection, prolonged renal dysfunction, and malignancies such as posttransplant lymphoproliferative disorder. This article focuses on medical issues before pediatric heart transplantation, according to the Korean Network of Organ Sharing registry and as well as major problems such as graft rejection and cardiac allograft vasculopathy. To reduce graft failure rate and improve long-term outcomes, meticulous monitoring for rejection and medication compliance are also important, especially in adolescents.
