Haq et al. observed that examination of sural-nerve biopsy specimens had a higher sensitivity than electrophysiological studies. 37 Likewise, Vallat et al. reported that 8 patients in a series of ...

Specimen from a Sural-Nerve Biopsy Showing Axonal Degeneration with Vacuolization (Arrowheads) of the Nerve Fibers (Panel A, Hematoxylin and Eosin, ×200) and a Sagittal, ...

The sural nerve, positioned beneath the skin’s surface in the back of your lower leg, plays a critical role in your body’s sensory network. As a component of the peripheral nervous system ...

Sural nerve and gastrocnemius muscle biopsy (Figures 5-8) showed transmural inflammation and necrosis of medium and small blood vessels, suggestive of active necrotizing vasculitis.

The dermal nerve-fiber diameter was consistently small (commonly <7 μm), whereas sural nerves can be large or small in diameter. Myelin internodes from glabrous skin were approximately 70 μm ...

A sural nerve biopsy performed in 1 patient showed axonal loss with no evidence of vasculitis. There was a lack of information on patient outcome, the FDA researchers comment, ...
