Abstract

Aim: To investigate the flow velocity values and resistance parameters determined by carotid artery doppler ultrasonography (DUS) examination in patients with trigeminal neuralgia (TN).
Materials and Methods: 79 patients diagnosed with TN and who underwent carotid DUS were included in the study. Spectral examination results were recorded for the TN side and the healthy side.
Results: Peak systolic velocity (PSV) internal carotid artery (ICA), resistive index (RI) (ICA) and PSV (ICA)/PSV external carotid (ECA) values in patients were relatively higher in arterial structures on the TN clinical side compared to the healthy side. RI (ICA)/RI common carotid artery (CCA) value was also high in arterial structures on the TN diagnosed side.
Conclusion: It was shown that especially ICA flow velocity and vascular resistance parameters increased in the carotid arterial system on the TN side. These findings indicate that flow parameters in the carotid artery system may also be effective in TN pathophysiology.

Karotis arteryel sistem vasküler akım parametreleri ile trigeminal nevralji arasında ilişki var mıdır?

Abstract

Amaç: Trigeminal nevralji (TN) hastalarında karotis arter doppler ultrasonografi (DUS) incelemesi ile saptanan akım hızı değerleri ve direnç parametrelerini araştırmak.
Gereç ve Yöntem: TN tanısı almış 79 hastaya karotis DUS yapıldı. Spektral inceleme sonuçları TN'li bölge ve sağlam bölge için kaydedildi.
Bulgular: Hastalarda peak sistolik hız (PSV) internal karotis arter (ICA), rezitif indeks (RI) (ICA) ve PSV (ICA)/PSV eksternal karotis (ECA) değerleri TN kliniği olan taraftaki arteriyel yapılarda sağlıklı tarafa göre nispeten yüksekti. RI (ICA)/RI common carotis arter (CCA) değeri de TN tanısı olan taraftaki arteriyel yapılarda yüksekti.
Sonuç: Özellikle ICA akım hızı ve vasküler direnç parametrelerinin TN tarafında karotis arteriyel sistemde arttığı gösterildi. Bu bulgular karotid arter sistemindeki akış parametrelerinin TN patofizyolojisinde etkili olabileceğini göstermektedir.
