目的：建立一种快速有效的大鼠腹腔异位心脏移植模型。方法：采用SD 大鼠作为受体，Wistar大鼠作为供体，行同种异位腹腔心脏移植，术后给以CsA5 mg/kg/d 灌服，心脏移植手术方法采用改良的Ono 术式，观察改良的腹腔异位心脏移植各步骤所需时间、术后成功率及主要并发症发生率。结果：共建立40 只大鼠异位心脏移植模型，手术成功率92.5 %。动脉吻合时间12.5± 2.3 min，静脉吻合时间12.3± 1.5 min，供心缺血时间37± 3.5 min，受体血管阻断时间34.2± 2.6 min，总手术时间90.2± 4.8 min，出现的主要并发症为出血和供心复跳失败（各占5 %、2.5 %）。结论：改进的大鼠腹部异位心脏移植技术是一种简便、快速、有效、成功率高的模型制作方法。

英文摘要:

Objective:To establish a rapid and effective heterotopic heart transplant model in rats.Methods:Allogeneic abdominal heterotopic heat transplantation was performed to make the SD rats as recipients and Wistar rats as the donors. After surgery, the rats were given the CsA5 mg/kg/d by gavage. The surgery of Ono style was further optimized based on the abdominal heterotopic heart transplantation, the time for each step, success rate and main complications after surgery.Results:40 rats' heterotopic heart transplantation models were established with the success rate of 92.5%, and the aortic anastomosis time was 12.5 ± 2.3 min, the pulmonary artery anastomosis time was 12.3± 1.5 min, total donor heart ischemia time was 37± 3.5 min, vessel occlusion time was 34.2± 2.6 min, and total time surgery was 90.2± 4.8 min. The main complications were bleeding and/or resuscitation for heart failure which occurred to 5%and 2.5%of experimental rats, respectively.Conclusion:Improved abdominal heterotopic heart transplantation is a simple, rapid, effective and high success rate method of model establishment.
