A cuff technique was applied to anastomose pulmonary vein,pulmonary arery andbronchus in rat receiving lung transplantation.In 6 consecutive cases,the average graft ischemictime was 17±3 rain,and the time for operation was 61±4 min.The time for ischemia was 1essthan one third of previous reports and the time for operation one forth of previous reports.Theoperation successful rate was 75%,and the survival rate was 100%on the postoperative day 7.After contralateral pneumonectomy,the blood gas analysis was normal,showing excellent graftfunction of the oxygenaration of the animals.
