[A new method of anastomosing severed nerves].

Area of Science:

• Neurosurgery
• Biomaterials Science
• Wound Healing

Background:

• Nerve repair is crucial for restoring function after injury.
• Traditional suturing can cause tissue damage and foreign body reactions.
• Fibrin glue offers a less invasive alternative for nerve anastomosis.

Purpose of the Study:

• To evaluate the efficacy of Fibrin glue (Fibrinkleber) for nerve anastomosis.
• To investigate the role of fibrinolysis inhibitors in protecting glued nerve repairs.
• To compare the outcomes of glued nerve anastomoses with sutured nerves.

Main Methods:

• Nerve segments were joined using Fibrin glue (Fibrinkleber).
• Inhibitors of fibrinolysis (natural and synthetic) were administered locally and systemically.
• The bond strength and foreign body reaction of glued anastomoses were assessed.
• Comparisons were made with traditional nerve suturing techniques.

Main Results:

• Fibrin glue protected nerve anastomoses from tissue plasminogen activators when combined with fibrinolysis inhibitors.
• Glued nerve anastomoses exhibited lower bond strength than sutured nerves.
• A reduced foreign body reaction was observed in Fibrin glue-repaired nerves.
• The combination of Fibrin glue and fibrinolysis inhibition demonstrated potential for nerve reunion.

Conclusions:

• Fibrin glue combined with fibrinolysis inhibition is a promising method for reuniting severed nerves.
• This technique may be particularly advantageous in nerve transplantation, provided tension is avoided.
• Further research is warranted to optimize bond strength and clinical application.
