Microvascular anastomosis using cyanoacrylate adhesives

Area of Science:

• Vascular Surgery
• Biomaterials Science
• Regenerative Medicine

Background:

• Microvascular anastomosis is crucial for tissue reconstruction.
• Conventional suture techniques can be time-consuming and technically demanding.
• The development of alternative, efficient anastomosis methods is essential.

Purpose of the Study:

• To introduce and evaluate a new cyanoacrylate adhesive technique for microvascular anastomosis.
• To compare the efficacy and safety of this adhesive method against traditional suture anastomosis.
• To assess the short-term patency and histological outcomes of the novel technique.

Main Methods:

• A cyanoacrylate adhesive was applied to the adventitia of overlapping vessel ends in canine radial arteries and cephalic veins.
• Sixteen microvascular anastomoses were performed using this technique.
• Vessel patency was assessed, and histological examination was conducted at 4 weeks.

Main Results:

• All sixteen anastomoses remained patent without evidence of thrombus formation.
• The adhesive did not penetrate the vessel lumen.
• Histological evaluation showed normal healing of the endothelium and internal elastic lamina at the anastomotic site.

Conclusions:

• The cyanoacrylate adhesive technique provides a rapid and straightforward method for microvascular anastomosis.
• This technique demonstrates excellent short-term patency and favorable histological healing.
• It presents a viable alternative to conventional suture anastomosis in microvascular surgery.
