A new technique of heterotopic heart transplantation in abdomen was developed on Wistar rats with fifteen experiments. This technique is characterized by termino-lateral anastomosis of donor aorta to recipient abdominal aorta cranially to renal arteries, and anastomosis of pulmonary artery of donor to left renal artery of recipient. The advantages of this technique are: the abdominal aorta of rats proximally to renal arteries is characterized by a well developed adventitia and its caliber is double of that of infrarenal aorta; b) the left renal vein is more easily access of caval vein with similar caliber; c) the use of left renal vein and the widening of pulmonary artery permits a wide anastomosis; d) the so obtained heart position is better than the transversal one; e) the calibers of all anastomosis is so wide to permit the realization of this technique without extreme optical magnification.
我们在Wistar大鼠上开展了15次实验，研发出一种新的腹部异位心脏移植技术。该技术的特点是将供体主动脉与受体肾动脉上方的腹主动脉进行端侧吻合，并将供体肺动脉与受体左肾动脉吻合。此技术的优点包括：大鼠肾动脉近端的腹主动脉外膜发达，其管径是肾下腹主动脉的两倍；b）左肾静脉更容易接入管径相似的腔静脉；c）使用左肾静脉以及肺动脉的加宽有利于进行宽大的吻合；d）如此获得的心脏位置优于横向位置；e）所有吻合口的管径都很宽，无需极高的光学放大倍数就能实施该技术。
