得克萨斯心脏研究所的外科医生于今年二月用激光施行了美国第一例冠状动脉内膜切除。该所利佛塞医生使用便携式二氧化碳激光器完成了这一实验过程。在此次打开心脏的手术中,外科医生在已被斑状物封闭的冠状动脉中插入激光器的针状尖头。利佛塞说手术相当成功,并说该所还计划总共进行20例试验。他设想每年150,000位进行冠状动脉旁通手术的病人中可能有10%至20%的人作为这一新型手术的候选人。
Surgeons at the Texas Heart Institute conducted the first US coronary artery resection with a laser in February this year. The Sullivan doctor used a portable carbon dioxide laser to complete the experiment. During this open heart surgery, the surgeon inserts the acicular tip of a laser into a coronary artery that has been blocked by a speckle. Lifu Sei said the operation was quite successful, and said the institute also plans to conduct a total of 20 trials. He envisions that as many as 10% to 20% of 150,000 patients undergoing coronary artery bypass surgery each year may be candidates for this new type of surgery.
