同种异体单肺移植7例报告(英文)

总结7例同种异体单肺移植资料的移植方案、肺保存及移植后管理监测情况。7例同种异体单肺移植患者中特发性肺纤维化3例,慢性阻塞性肺病2例,双侧矽肺、肺气肿1例,双肺结核右毁损肺1例。7例供体均为脑死亡者,供肺均采用Euro-Colins液或低钾右旋糖酐液灌注并良好保存。受体与供体血型匹配,5例患者行右侧单肺移植,2例行左侧单肺移植。肺支气管、肺动脉为端端吻合,肺静脉为心房-心房吻合。移植前后均常规应用抗生素和免疫抑制剂。肺移植后进行全面指标监测,包括心肺功能、抗生素使用及免疫抑制药物的调整。7例患者均未出现支气管、肺动静脉吻合口并发症。5例移植后2个月内死亡,1例存活近1年,另1例存活近2年。死亡者中4例死于肺感染导致多脏器功能衰竭,1例死于多曲霉菌感染致严重肺出血。6例移植后出现排斥反应,其中1例出现3次。肺移植手术适应证的选择、供肺的选择和保存、肺移植操作以及移植前后的管理已逐渐成熟,移植前心肺功能差者、移植后使用免疫抑制药物同时合并严重感染者病死率仍很高。

Allogeneic single lung transplantation in 7 cases

The present case report was designed to summarize the clinical experience of operative technique, lung preservation, lung perfusion, and perioperative management. Of 7 cases who underwent allogenic single lung transplantation (LT), 3 were idiopathic pulmonary fibrosis, 2 were chronic obstructive pulmonary disease, 1 was silicosis, emphysema, and bulla, and 1 was tuberculosis in both sides and presented with destroyed lung in one side. All donors were already brain death. Donor lungs were well preserved utilizing Euro-Colins liquid or low- potassium dextran solution. Donors and recipients were matched in blood type. Of 7 cases selected, 5 received single right lung transplantation, and 2 received single left LT. End-to-end anastomosis was performed for pulmonary branches and pulmonary arteries, while atrium-to-atrium anastomosis was performed for pulmonary vein. Antibiotics and immunosuppressants were routinely used prior to and subsequent to LT. Following LT, heart and lung function, usage of antibiotics, and adjustment of immunosuppressant were monitored. Stomal complications regarding bronchus and pulmonary artery and vein did not appear in any patient. Five cases survived for about 2 months, one for approximately 1 year, and one for nearly 2 years. Four cases died of multi-organ failure caused by pulmonary infection, and one of severe pulmonary hemorrhage caused by aspergillus sydowi infection. Rejection occurred in 6 cases. One case suffered from rejection three times. Selection of indication, selection and preservation of donor lung, LT operation and pre- and post-operative management of LT have acquired satisfactory achievements. High mortality occurred in patients with preoperative poor cardiac and pulmonary functions and postoperative severe infections accompany with application of immunosuppressant.
