Abstract
|
|
|
Recently ultrasonic echoencephalography has effectively been used for diagnosing the intracranial lesions. It has been originally described by Leksell in 1955 as a effective method to diagnose the traumatic intracranial lesions.
We have performed the echoencephalography in 157 patients admitted to Woo Sok Medical College Hospital for the treatment of he injuries, during the period from March, 1967 to September, 1967.
Operations were performed in 91 of 157 cases, and angiography had been done in 68 of 157 in this series. The diagnostic value of the echoencephalography was evaluated and compared with the results of the carotid angiography as well as operative findings.
Summarize results were as follows:
1. Shifting of the midline echos (M-E) were demonstrated in 59 of 73 cases of hematoma group (about. 81%) and 133 of 157 cases of total examinations (about 81.5%).
2. Hematoma echos (H-E) were revealed only in the 30 of 73 cases of hematoma group (42%).
3. Echoencephalography is likely not valuable to diagnose the mass lesions such as tumor or hematoma located in the posterior fossa or in the skull base.
4. Carotid angiography revealed much more diagnostic accuracy and detailed information, and in this study 54 of 60 angiographic abnormalities (90%) were proved by surgeries.
5. Although ultrasonic echoencephalography could not show detailed information and lower percentage of accuracy than the angiographic examination, it had considerable diagnositic accuracy and specific value in the patients especially such as, serious acute head injury cases which necessitate a rapid, harmless and easy method.
6. To obtain the further detailed information and accuracy by the ultrasonic echoencephalography, it is expected the introduction of combined equipment of the A and B scope types of the ultrasonic echoencephalography in early future.
