Application of color Doppler ultrasound in normal full-term infant intracranial venous system / 中华超声影像学杂志

ABSTRACT

ObjectiveTo observe ultrasound images of normal full-term intracranial venous system,in order to provide reference images and guidelines for clinical practice.Methods Courser shape and spectrum characters by anterior fontanel acoustic window of 65 normal newborn infants had been observed.Results①The demonstration of subendymal vein,cerebral vein,Galen vein longitudinal sinus,straight sinus,lateral sinus confluence was 100％,that of basal vein and falcial sinus was 21％ (14/65) and 29％ (19/65),respectively.②The flow rate of a cranial vein decreased.③ In the overall 65 cases,9 ependymal veins,intracranial veins,Galen veins,62 sinus rectus,63 lateral sinuses,65 longitudinal sinuses and confluence sinuums had impulsive blood spectrum.A basal vein had impulsivity in 14 cases.4 of 19 falcial sinuses had impulsivity.Conclusions Color Doppler ultrasound can identify intracranial veins effectively,but some limitations must be taken into account.Blood flow rate of Galen vein sinus confluence is immeasurable.
