The low energy carbon dioxide laser adaptation to the operation for coronary bypass surgery and splenorenal shunt has been now achieved experimentally. Magnetic flowmetry,angiographic and historical studies were carried out immediately after surgery(acute experiment). Coronary bypass utilizing <CO_2> laser resulted in 7 anastomosis in 5 dogs and splenorenal shunts with reimplantation of the right renal vein were 7 dogs.Angiographic patency of of the bypass and shunt at interval of one month to 6 months after anastomosis were 70% and 85% respectively. The technique produced the most secure laser anastomosis was considered that stay sutures was used as an aid in position.

目前已在实验上实现了低能量二氧化碳激光对冠状动脉搭桥术和脾肾分流术的适应性。术后立即进行磁流量计、血管造影和历史研究（急性实验）。5<CO_2>只犬行激光冠状动脉旁路移植术，7只犬行脾肾分流术并右肾静脉回植术，术后1 ~ 6个月造影通畅率分别为70%和85%。认为产生最安全的激光吻合术的技术是使用留置缝线辅助定位。
