Abstract

Somatosensory (SEP), brainstem auditory (BAEP), and visual (VEP) evoked potentials have been shown to be useful in detection of brain cortical dysfunction in patients with subclinical hepatic encephalopathy (SHE). In this study, involvement levels of SEP, BAEP and VEP studies in the subclinical hepatic encephalopathy have been investigated. Somatosensory evoked potentials (49 %) were more frequently affected than brainstem auditory (38.1 %), and visual evoked potentials (11%). BAEP abnormalities accompanying SEP abnormalities were seen frequently. Electroencephalography examination has showed baseline rhythm irregularity that was made up of slow activity in 22 % of the cases. Consequently, evoked potentials, prominently Somatosensory evoked potentials, are objective electrophysiological tests that contribute in diagnosis of subclinical hepatic encephalopathy and EEG provides supportive data.

Özet

Subklinik hepatik ansefalopatili olgularda, somatosensoryel (SEP), beyin sapı işitsel (BAEP), ve visual (VEP) uyarılmış potansiyeller kortikal fonksiyon bozukluğunu göstermede yararlı olmaktadır. Bu çalışmada SEP, VEP ve BAEP incelemelerinin SHE'lerde etkilenme dereceleri araştırıldı. SHE'li olgularda öncelikle somatosensoryel sistemin (% 49) etkilendiği, daha sonra beyin sapı uyarılmış potansiyellerin (% 38.1) ve en az etkilenmenin görsel sistemde olduğu (% 11) görülmüştür. BAEP anormalliğinin daha çok SEP anormalliğine eşlik ettiği dikkati çekmiştir. EEG % 22 olguda yavaş aktiviteden oluşan zemin ritmi düzensizliği göstermiştir. Sonuçta, uyarılmış potansiyellerden öncelikle somatosensoryel daha sonra beyin sapı işitsel ve visual potansiyellerin subklinik hepatik ensefalopati tanısına katkıları olan objektif birer elektro fizyolojik testler olduğu, hatta EEG incelemesinin de tanıyı destekleyici veriler sağladığı görülmüştür.
