Sural Sinir İletim Çalışmalarında Yakın Sinir Yönteminin Özgüllüğü

Amaç: Sağlıklı bireylerde yapılan sural sinir iletim çalışmasının yanlış pozitif oranın saptanması. Gereç ve Yöntem: Yirmi üç tane sağlıklı bireyin (ortalama yaşı: 51, aralık: 26-74, 11 erkek, 12 kadın) sural sinirleri hem yüzeyel elektrod hem de yakın sinir tekniği ile tek taraflı olarak incelendi. Bulgular: Sural sinirin yüzeyel elektrod kullanarak yapılan sinir iletim incelemesinde tüm deneklerin sinir iletim incelemeleri normal bulunurken yakın sinir tekniği ile 3 denekte hem duysal sinir aksiyon potansiyeli amplitüdü hem de şekli anormal bulundu. Sonuç: Yakın sinir tekniği ile sural sinir incelenmesi normal bireylerde anormal sonuç verebilmekte olup, şüphede kalınan olgular mutlaka özgüllüğü daha yüksek metotlar ile tekrar değerlendirilmelidir.

The Specificity of Near Nerve Method on Sural Nerve Conduction Studies

Objectives: To determine the false positive rate of sural nerve conduction studies for healthy subjects. Materials and Methods: We performed sural nerve conduction studies for 23 healthy subjects using both nerve-nerve technique and surface recording. Results: We found three abnormal results in the sural nerve-nerve technique. However, all those patients had normal results in the surface recording. Conclusion: The surface recording is recommended for suspicious cases in order to approve the abnormal results in the near-nerve technique.
