Microarterial sutureless sleeve anastomosis using a polymeric adhesive: an experimental study

Area of Science:

• Vascular Surgery
• Biomaterials Science
• Microsurgery

Background:

• Conventional microarterial anastomosis relies on sutures, which can be time-consuming and technically demanding.
• Suture techniques may lead to complications such as stenosis or intimal damage.

Purpose of the Study:

• To describe and evaluate a new sutureless microarterial anastomosis technique.
• To assess the efficacy and reliability of using a polymeric adhesive for vascular repair.

Main Methods:

• A novel technique involving telescoping vessels and applying iso-propyl-cyanoacrylate was developed.
• Sixty-six anastomoses were performed on rat femoral arteries.
• Histological and electron microscopic evaluations were conducted from immediate to 90 days postoperatively.

Main Results:

• A high patency rate of 95% was achieved in the performed anastomoses.
• The sutureless method was observed to be faster and easier than conventional suture anastomosis.
• Tissue reaction to the adhesive was minimal, primarily adventitial, and did not compromise vessel patency.

Conclusions:

• Sutureless microarterial anastomosis using iso-propyl-cyanoacrylate is a viable and effective alternative to traditional suturing.
• The technique offers advantages in terms of speed, ease of performance, and reliability.
• Minimal adverse tissue response suggests good biocompatibility of the adhesive for vascular repair.
