摘　　要：目的应用连续缝合间断打结法吻合动脉建立小鼠心脏移植模型。方法近交系C57BL/6j^((H-2b))、BALB/c^((H-2d))小鼠各30只,建立小鼠腹部心脏移植模型(C57BL/6j→BALB/c),连续缝合间断打结法端侧吻合供体升主动脉和受体腹主动脉;一针后壁先缝法连续吻合供体肺动脉和受体下腔静脉。观察移植心脏搏动持续时间及受体生存时间。结果手术成功率90%(27/30),总手术时间(91.77±6.70)min,动脉吻合时间(24.63±1.67)min,静脉吻合时间(15.17±1.80)min。供心中位存活时间8天,病理组织学示典型排斥反应。结论应用连续缝合间断打结法吻合动脉降低了小鼠心脏移植的手术难度,效果可靠,值得推广。Objective To evaluate the feasibility of continuous-interrupted method for arterial anastomoses in mouse model of heart transplantation. Methods Heterotopic heart transplantations were performed from inbred C57BL/6j^（（H-2b））mouse（n=30）to BALB/c^（（H-2d））mouse（n=30）,in which the graft′s ascending aorta was anastomosed end-to-side to the recipient′s aorta by continuousinterrupted sutures,and the pulmonary artery was anastomosed end-to-side to the inferior vena cava by continuous one-suture anastomosis.The survival time of grafts and the duration of cardiac impulse were observed. Results The successful rate of transplantation was 90%（27/30）.Total operation time was（91.77±6.70）min with,arterial anastomosis time of（24.63±1.67）min and venous anastomosis time of（15.17±1.80）min.Median beating time of donor heart was 8 days with acute rejection reaction indicated by pathological histology. Conclusions The technical difficulties of arterial anastomosis were reduced greatly by continuous-interrupted method,and we recommended this method for mouse heterotopic cardiac transplantation.
