“…IVaS, "Clip-stent" followed by "Pull-out stent" techniques have been described in recently published studies. 7,8 The IVaS technique is based on a technique in which a silastic tube is inserted into the vascular lumen to facilitate suturing of vessels larger than 1 mm. 5 Although there are no studies showing the superiority of IVaS, it can be applied according to the surgeon's preference.…”

“…6 The "clip stent" technique was developed due to the complications and difficulties encountered during the removal of the stent during IVaS application. 7 This "Clip-stent and Pull-out stent" technique has many advantages. 8 The possibility of damage to the vascular intima during anastomosis is reduced.…”

“…In general, the benefits of stenting are better patency of vascular anastomoses, more regular sutures, and fewer posterior wall sutures. 5,7,8 The main disadvantage is leakage from the needle exit hole as its diameter constantly exceeds that of the suture, which can cause parietal tears. A "Pull out stent" is theoretically better than a "Clip-stent" because it uses a needle-free suture and enters the vessel wall through a single hole.…”

“…6 Therefore, the "clip stent" technique was recommended to improve the IVaS technique. 7 In this technique, the double-needle monofilament suture is placed in the lumen of both ends of the vascular anastomosis and then the needle is passed through the vessel wall and pulled out from both sides, and the anastomosis is completed with the help of this stenting. An advantage of this technique is that stent removal is not traumatic.…”

“…The disadvantage is that it causes leaks in each of the two remaining holes after needle removal. 7 It has been proposed to develop the "clip stent" technique to perform microsurgical anastomoses, by showing that it can be applied as a single needle with a technique called "pull out stent", which can be improved by removing the needles and placing and removing the stent with one hole in two places. 8 In this study, we further developed these two techniques, which were developed to keep the vessel lumen open during microsurgical vessel anastomosis, and defined a new technique we named "folded stent".…”

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.
