IS RETROGRADE AMNESIA, BY ITSELF, AN INDICATION FOR CRANIAL COMPUTERIZED TOMOGRAPHY?

Retrograde amnesia due to minor head injury (Glasgow coma score=15) is frequently encountered in the emergency services. The aim of this study is to find out if cranial computerized tomography (CT) is necessary in patients with pure retrograde amnesia and without any other neurological findings and/or symptoms of increased intracranial pressure. We performed cranial CT in WO consecutive such patients with retrograde amnesia. 95 CT scans were normal and 5 abnormal (5%). These findings are in accordance with the literature (4-6%). We, therefore think that we must continue to consider retrograde amnesia, by itself, as an indication for computerized cranial tomography.

RETROGRAD AMNEZÝ TEK BAÞINA BÝLGÝSAYARLI BEYÝN TOMOGRAFÝSÝ ÇEKTÝRME ENDÝKASYONU MUDUR ?

Minör kafa travmasýna (Glaskow Koma Skoru: 15) baðlý retrograd amnezi olgularý acil hekimlerinin çok sýk rastladýðý bir durumdur. Bu nedenle herhangi bir nörolojik bulgu taþýmayýp sadece retrograd amnezisi olan olgularda Bilgisayarlý Beyin Tomografjsinin (BBT) ne kadar gerekli olduðunu araþtýrmak amacý ile bu çalýþma yapýlmýþtýr. Retrograd amnezi dýþýnda herhangi bir nörolojik defisiti bulunmayan ardýþýk 100 olguya BBT çekilmiþtir. Bu olgularýn 5'inde patoloji saptanmýþ, 95 BBT normal bulunmuþtur. Bu bulgular literatürle uyumludur (%4-6). Bu nedenle retrograd amnezinin yandaþ semptom ve bulgular olmadan da tek baþýna BBT endikasyonu olarak devam etmesi gerektiði sonucuna varýlmýþtýr.
