Närvivõttete

Närvivõttete, also known as nerve grafts or nerve transplants, are surgical procedures used to repair or bridge gaps in damaged peripheral nerves. This technique involves taking a segment of nerve tissue, typically from another part of the patient's body (autograft), and using it to bridge the injured area. In some cases, synthetic conduits or grafts from donors (allografts) may also be employed, though these carry higher risks of rejection or limited success.

The primary goal of närvivõttete is to restore continuity to a severed or damaged nerve, allowing for the regeneration of nerve fibers (axons) across the graft. This regeneration is crucial for restoring sensory and motor function to the affected limb or body part. The success of the procedure depends on various factors, including the type and extent of nerve damage, the patient's age and overall health, and the skill of the surgical team.

Närvivõttete are typically considered when direct nerve repair is not possible due to a significant gap between the severed nerve ends. The nerve segment used as a graft is carefully chosen to match the size and type of the damaged nerve. Post-operative rehabilitation, including physical therapy, is an essential component of recovery to maximize the functional outcome. While promising, nerve regeneration is a slow process, and full recovery can take many months or even years. Complications can include infection, graft failure, and incomplete functional recovery.
