Scanning electron microscopic observation of microvascular anastomosis with nitinol clip / 中华显微外科杂志

ABSTRACT

Objective To analysis the scanning electron microscopic (SFM) results of the anastomosis site performed by nitinol clip in rabbits Methods The nitinol clip technique for microvascular anastomosis was tested experimentally and compared with the conventional 9 0 end to end suturing technique Ten carotid arteries on one side of 10 rabbits were ananstomosised using nonpenetrating microclips made of nitinol, and the other 10 carotid arteries on one side of 10 rabbits were ananstomosised. using nonpenetrating microclips made of nitinol,and the other 10 carotid arteries on the other side were sutured in a conventional way with 9 0 monofilament nylon Biopsy was performed in two groups of rabbits at different time intervals postoperatively, and the specimens were examined under scanning electron microscopy Results Twenty microvascular anastomoses were patent SEM examination of the anastomotic site revealed major differences between sutured and stapled groups Conclusion Stapled microvacular anastomosis technique is fast and reliable
