Abstract:
Objective To observe clinical significance、anatomy and variation of normal internal cerebral veins and their tributa-ries.Methods The studies included 284 sides in 142 patients.The patients were performed with 320-detector Row CT One-stop Scanning.Then,the anatomical features of internal cerebral veins and their tributaries were evaluated.Results The detection rate of internal cerebral veins(ICA)、thalamostriate veins(TSV)、septal veins(SV)、anterior caudate nucleus veins、posterior caudate nucleus veins and lateral direct veins was 100%、100%、98.9%、95.4%、93.7%、48.6%.Type of IA was seen frequently in four types of ICA,the parts of ICV and their tributaries were mirror symmetry,the majorities of ICA were located the same plane.Anterior cau-date nucleus veins were classified four types on basis of these different draining patterns,they were drained to TSV commonly.There was no significant difference between venous angle or false venous angle and type of their draining(P>0.05).There was significant difference between detection rate of lateral direct veins and development of posterior caudate nucleus veins(P<0.05).Conclusion 320-detector Row CT One-stop Scanning was an important method that internal cerebral veins were detected effectively and non-inva-sively,observed anatomy,course and morphological change of ICV.
