Transcranial color-coded sonography with and without contrast enhancement in observation of cranial venous sinus thrombosis / 中国介入影像与治疗学

ABSTRACT

Objective: To explore the value of transcranial color-coded sonography (TCCS) and contrast-enhanced transcranial color-coded sonography (CE-TCCS) in diagnosis of cerebral venous sinus thrombosis (CVST) and hemodynamic changes of great cerebral vein and basal veins. Methods Totally 22 patients with intracranial transverse sinus and/or straight sinus thrombosis diagnosed with DSA and/or MR venography (MRV) were selected (CVST group) and underwent TCCS and CE-TCCS, while 68 patients with other diseases were included in control group and underwent TCCS. The display rate and hemodynamic changes of the great cerebral vein, basal veins and venous sinuses of both groups were observed and compared. Results: In CVST group, direct sinus thrombosis, left transverse sinus thrombosis and right transverse sinus thrombosis were determined with TCCS in 13, 20 and 17 cases, respectively, and there were statistically significant differences between the results of TCCS and DSA and/or MRV (all P0.05). The display rate and peak flow rate of the great cerebral vein and basal veins in CVST group were higher than those in control group (all P<0.05). Conclusion: CE-TCCS is similar in observation on cerebral venous sinus thrombosis to DSA and/or MRV. TCCS can display the great cerebral vein and basal veins and increased venous flow after venous sinus thrombosis, indicating the possibility of cranial venous sinus thrombosis.
