Summary
The novel "pull out stent" technique simplifies blood vessel anastomosis, proving faster and less traumatic than other methods. This innovation offers improved vessel repair with fewer leaks, benefiting microsurgery applications.
Area of Science:
- Vascular Surgery
- Microsurgery Techniques
- Surgical Innovation
Background:
- The intravascular stent technique (IVaS) was developed to simplify submillimeter blood vessel anastomosis.
- The "clip stent" variation of IVaS improved vessel patency.
- A new technique, the "pull out stent", was developed to minimize vessel trauma during anastomosis.
Purpose of the Study:
- To analyze the efficacy of the "pull out stent" technique in reducing vessel trauma.
- To compare the "pull out stent" technique with interrupted sutures, IVaS, and the "clip stent".
Main Methods:
- An experimental study was conducted on 4 groups of 10 rats each.
- Rat tail artery anastomosis was performed using interrupted sutures, IVaS, "clip stent", or "pull out stent".
- The "pull out stent" involved intraluminal/transluminal introduction, anastomosis, and stent removal.
Main Results:
- The "pull out stent" technique demonstrated a shorter anastomosis procedure time compared to the "clip stent".
- Patency and number of stitches were similar across all groups.
- The interrupted suture group had more leaks; the "pull out stent" resulted in fewer leaks.
Conclusions:
- The "pull out stent" technique is faster, less traumatic, and results in fewer leaks than other methods.
- This technique allows for more regular sutures during vessel anastomosis.
- Potential clinical applications include digital vein anastomosis in replantation and toe transfers, particularly in pediatric cases.
