Methods Adult New Zealand white rabbits (n=10) as recipients were divided into 5 groups and one-month age New Zealand white rabbits (n=20) served as donors. The homograft valved conduits harvested from the donors were transplanted into the bilateral aorto-carotid in 10 recipients. The homografts were harvested from one group at 7, 14, 28, 60, 120 days after transplantation to examine blood flow and thrombus of homografts.

成年新西兰兔10只作为受体分5组。1个月龄的新西兰白兔20只作为供体，取其主动脉带瓣血管，移植于受体的两侧颈动脉，术后7、14、28、60、120 d分别取出每组受体所移植的同种瓣并观察血流通常情况及有无血栓形成。
