Dystrophic changes in the sciatic nerve: a comparison of ultrasonographic and morphological data (pilot study)

Abstract

Objective. To study the possibility of using ultrasonography to identify mild (early), moderately severe and significantly severe dystrophic changes in the sciatic nerve.Materials and methods. To achieve this goal, we compared ultrasonographic and histological data from 15 pairs of sciatic nerves taken from 8 men and 7 women aged 58 (52; 68) years who had been treated for different oncological diseases and died in 2022 from the underlying disease.Results. Parallelism was revealed between the ultrasonographic pattern in mild, moderately severe and significantly severe dystrophic changes of the sciatic nerve, on the one hand, and the histological and immunohistochemical patterns, on the other hand.Conclusion: Ultrasonography (B-mode) allows identifying mild, moderately severe and significantly severe dystrophic changes of the sciatic nerve.
