Background: According to American Academy of Neurology (AAN) criteria, demonstration of demyelination in the sural nerve by teased fiber or ultrastructure is considered mandatory for diagnosis of chronic inflammatory demyelinating polyneuropathies (CIDP). References. Nerve biopsy findings. Argov et al. Common nerves subjected to biopsy are the following: superficial peroneal; sural; superficial radial sensory; gracilis; The gracilis nerve is a motor nerve that supplies the gracilis muscle in the thigh.

I only had a skin biopsy to determine the severity of SFN, small fiber neuropathy. Anatomy and Physiology The sural nerve provides sensory feedback from the lateral ankle and foot. The sural nerve is a sensory nerve in the calf region (sura) of the leg. It forms from two branches of periphery nerves: the tibial nerve and the peroneal nerve. Because the sural nerve is relatively superficial, it is easily blocked at multiple levels at or above the ankle.

A small cut is made, and the nerve is carefully exposed. It didn't actually show vasculitis or infiltration, but did show demylination and axonal damage. A nerve biopsy is a minor operation to remove a small sample of nerve for pathological testing to aid diagnosis. The most common convergence of the sural nerve is when both the medial and lateral sural nerves join (40.2% to 83.7%) (18). It is located behind the ankle.

You will be asked to lie down, and a local anesthetic will be given where the biopsy will be taken. (2000) based on abnormalities of ovoids on teased fibres, and poor evidence of regeneration; ulnar motor and sensory neural conduction and amplitude and no significant .

Less commonly, the distal sural nerve may have contribution from only the medial sural nerve (13.3% to 53.8%), and from only the lateral sural nerve in rare cases (0 to 16%) (18).

However, if damage does occur, it can be treated by removing part of the nerve. A nerve biopsy is most often done on a nerve in the ankle, forearm, or along a rib. A sural nerve biopsy may be useful to enable the clinician to diagnose the etiology and underlying pathology of patients presenting with symptoms of a peripheral neuropathy, when no clear underlying cause has been determined with conventional assessment such as electrophysiology or quantitative sensory testing.

The nerve sample is sent to a lab, where it is examined . Specimens were then fixed in 2.5% glutaraldehyde. This review briefly summarizes the nature of sensory and autonomic nerve dysfunction and presents these findings in the context of diabetes-induced nerve degeneration mediated by alterations in mitochondrial ultrastructure, physiology and trafficking.
