Meanings of Stereoview in Cerebral Angiogram

뇌혈관 조영술에서 입체촬영의 의의

Many pictures must be taken for the presumption of the stereorelation of the cerebral artery, which obtained with ordinary cerebral angiography. And it is very difficult to understand the stereoimage and required many experiences. But it is able to presume the stereorelationship in only brief eye's training without the aid of the stereoscope using the prism. For the stereoview, we need the paired angiograms obtained only straight and tilting the X-ray tube. In practice, with this stereoview in cerebral angiogram, we could know the directions of the aneurysmal neck and fundus with the stereorelationship of the cerebral artery and indeed helps us greatly in operation field. In addition, we might guess the location and stereorelationships of the feeding artery and draining vein in arteriovenous malformation and other vascular tumors and it was great aid in diagnosis and operation. Now we present the methods of the pictures for the stereoview in cerebral angiogram and the methods for eye's training.

다음과 같은 결론을 얻었다. 1. 입체경이나 여러 장의 입체상의 촬영 없이도 눈의 적응 훈련만으로 간단히 입체상을 볼 수 있다. 2. 뇌동맥류의 방향과 주위 혈관과의 관계, 뇌동 정맥 기형에서 공급동맥과 유출정맥, 종양과 그 주위 혈관 관계를 정확하게 알 수 있어 수술에 큰 도움을 줄 수 있다. 3. 수술시야의 단면사진에서도 역시 입체상을 볼 수 있어 의학예술이라고 의의를 둘 수 있다.
