Abstract: 【Objective】 To evaluate the performance of the magnetic artificial blood vessel device for fast non-suture anastomosis of caval reconstruction with artificial blood vessel transplantation after resection in canines. 【Methods】 Sixteen adult mongrel dogs of either gender were randomly divided into two groups for vena cava reconstruction with artificial blood vessel transplantation after inferior vena cava (IVC) resection. Group MCA (n=8): magnetic artificial blood vessel device for IVC reconstruction; Group manual sewing (MS) (n=8): hand suturing for IVC reconstruction. Operation time and stoma errhysis were recorded during operation. Patency and stoma stenosis were confirmed via color Doppler ultrasound scanning and X-ray cholangiography at different time points as late as 4 weeks after surgery. 【Results】 The time required to perform the vascular anastomosis was significantly shorter for the magnetic artificial blood vessel device (6.25±2.25)min than for MS (27.32±5.12)min (P<0.001). There were four cases of stoma errhysis in MS group which had to be repaired (P=0.077). Vascular X-ray angiography and color Doppler ultrasound found normal blood flow and no stoma stenosis in MCA group, but three cases of stoma stenosis in MS groups (P=0.200). Compared with MS group, the magnetic ring device stoma was associated with smooth re-endothelialization and depressed infiltration of inflammatory cells at the anastomotic site. 【Conclusion】 The magnetic artificial blood vessel device offers a simple, fast, reliable, and efficacious technique for vena cava reconstruction with artificial blood vessel transplantation.
