한국인 곧은정맥동의 변이

Abstract

The complexity in development of the dural sinus mar result in many variations. Swdies are being done on the variations of the straight sinus for clinical application of neurological diagnosis and operation. However, no data is available on Koreans, which made this study necessary. The present study was made on 50 Korean adult cadavers(average age of 67). The results were as following: 1.A bulbous formation of the rostral aspect of the Straight sinus was present in 22 cases(44%), 2.Complete double straight sinus was present in 3case5(6%). 3.Partial septum was observed in 8 cases(l6%) with varied position and length. 4.The straight sinus terminated into both transverse sinuses (52%), the left transvetse sinus(24%), the confluence of sinus-es (18%), and the right transverse sinus(6%). 5.Average length and width of the straight sinus were 48.5mm and 5.0mm, respeclivdy. 6. Nineteen cases(38%) showed no tentorial sinus drainage into the straight sinus on both sides. Number, size and termination of the tentorial sinus were various.
