Abstract

Objective: Although microsurgical vessel anastomoses have become a routine procedure today, they are still among the difficult techniques to apply. The most important step in the success of the technique is the clear presentation of the vessel lumen. In this study, we aimed to describe a new technique that will provide an easier anastomosis by keeping the lumen open during microvascular anastomoses.
Methods: Four groups were formed using the chicken wing radial artery, which is an inanimate animal model. One of these was the control group who underwent standard microvascular repair. The second and third groups that followed were those in which two previously defined intravascular stenting techniques were applied. The fourth group was the Folded stent group that we just defined.
Results: Anastomosis time was found to be significantly longer when compared to other groups in our newly defined technique. This time was an average of 3 minutes. No significant difference was observed in terms of the number of sutures used in anastomoses. No posterior wall suture complication was observed in any specimen.
Conclusions: “Folded-Stent” technique provides a great advantage over other stenting techniques in terms of keeping the lumen open during the anastomosis and preventing the adhesion of the vessel walls. It is an advantageous technique that can be used in clinical practice, especially during venous repairs, to prevent posterior wall suturing of small caliber vessels.
