Repair of peripheral nerve with vein wrapping

Area of Science:

• Regenerative Medicine
• Peripheral Nerve Surgery
• Biomaterials in Surgery

Background:

• Post-traumatic neuro-anastomosis requires protection from the environment to prevent complications like painful neuroma formation.
• Current methods for neuroma prevention lack consensus and efficacy.
• A biologically inert, biodegradable, and non-compressive barrier is needed for nerve repair.

Purpose of the Study:

• To evaluate the efficacy of using a venous sheath for neuro-anastomosis.
• To assess the reduction of painful neuromas formation.
• To improve electrical conductivity and manage discrepancies in sectioned nerve stumps.

Main Methods:

• A comparative study of 26 patients with peripheral arm nerve injuries.
• Group A (16 patients): End-to-end nerve suture wrapped in a vein sheath.
• Group B (10 patients): Simple end-to-end neurorrhaphy (control).

Main Results:

• Average follow-up of 14 months.
• Group A demonstrated more rapid motor and sensory recovery compared to Group B.
• Group A experienced a reduction in painful symptoms.

Conclusions:

• Venous sheath wrapping is an effective solution for nerve repair.
• It prevents nerve fiber dispersion, adherent scars, and painful neuromas.
• This technique facilitates faster functional recovery and accommodates size discrepancies without costly equipment.
