Experimental study of the low energy carbon dioxide laser for cardiovascular surgery

实验上实现了低能量二氧化碳激光在冠状动脉搭桥术和脾肾分流术中的应用。术后立即进行磁流量测量、血管造影和病史研究(急性实验)。应用~lt；CO_2&GT；激光冠状动脉搭桥术5条犬7条，脾肾分流加右肾静脉再植术7条，术后1个月~6个月血管通畅率分别为70%和85%。该技术产生了最安全的激光吻合术，被认为是支撑缝线作为辅助的位置。

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.
