摘　　要：目的 利用磁性压榨式吻合（MCA）技术自制新型磁性吻合环,探讨其快速无缝线吻合血管的可行性.方法 西安近郊杂种犬12只,雌雄不限,6～8月龄,体质量（16.5±3.6） kg.每只的犬左、右侧股动脉分别行MCA与手工缝合,观察并比较两种缝合技术吻合股动脉耗时、术中渗漏血情况,术后6周行超声心动图与血管X线造影检查吻合口血流及并发症情况.结果 MCA血管吻合耗时（3.89±1.16） min,手工缝合（14.16±3.72） min,两者差异有统计学意义（P =0.000）.MCA术中吻合口无渗漏血发生,手工缝合有6例因吻合口渗漏血再行修补术.血管X线造影与超声心动图检查示MCA吻合口血流通畅,无狭窄及血栓形成,通畅率100％;手工缝合术后2～4周,并发吻合口狭窄4例、闭塞1例.结论 新型磁性吻合环及MCA提供了一种简单、快速且吻合效果可靠的动脉血管吻合方法,有利于减少术后吻合口并发症,加快手术恢复.Objective To investigate the magnetic pinned-ring device for non-suture vascular anastomosis.Methods Twelve adult mongrel dogs of either gender were randomly divided for femoral artery in situ end-to-end anastomosis,one side of the femoral artery was anastomosised with MCA,and the other side of the femoral artery was anastomosised by hand suturing in each dog.Operation time and stoma errhysis were recorded during operation.Patency and stoma stenosis was confirmed via color Doppler ultrasound scans and X-ray cholangiography at different time points as late as 6 weeks after surgery.Results The time required to perform the vascular anastomosis was significantly shorter for the magnetic device than hand sewing[（3.89± 1.16） min vs.（14.16 ±3.72） min,P =0.000].There were 6 patients who happened stoma errhysis during femoral artery hand-sewing anastomosis,and needed to be repaired.Vascular X-ray angiography and color Doppler ultrasound found blood flow magnetic anastomosis group normal with 100% patency rate and there wasn＆#39;t stoma stenosis,but one stoma occlusive and four stoma stenosis in the manual suture groups.Conclusion The magnetic pinned-ring device offers a simple,fast,reliable,and efficacious technique for non-suture artery anastomosis.Application of the MCA technique can effectively reduce the complication caused by operation technique,resulting in smooth operation and improved prognosis.
