This study aimed to determine the detection rate of transcranial color-coded sonography (TCCS) of cerebral veins and sinuses and to explore the diagnostic accuracy of TCCS for straight sinus (SS) and transverse sinus (TS) thromboses. The detection rates of cerebral veins and sinuses using TCCS and contrast-enhanced TCCS (CE-TCCS) were analyzed. The diagnostic accuracy of CE-TCCS was evaluated. Median time from symptoms to CE-TCCS was 10 (range, 1-150) d. The detection rate of bilateral basal veins of Rosenthal was 100% by CE-TCCS, followed by right TS (91.89%), SS (88.12%), left TS (74.59%) and vein of Galen (70.27%). Compared with magnetic resonance imaging/magnetic resonance venography, CE-TCCS showed 100% sensitivity and 96.3% specificity for SS thrombosis, 100% and 100% for right TS thrombosis and 100% and 94.4% for left TS thrombosis. In conclusion, CE-TCCS shows high identification rates of cerebral veins and sinuses and a high diagnostic accuracy for SS and TS thrombosis.
本研究旨在确定经颅彩色多普勒超声（TCCS）对脑静脉和窦的检测率，并探讨 TCCS 对直窦（SS）和横窦（TS）血栓形成的诊断准确性。分析了 TCCS 和对比增强经颅彩色多普勒超声（CE-TCCS）对脑静脉和窦的检测率。评估了 CE-TCCS 的诊断准确性。CE-TCCS 检查从症状出现到检查的中位时间为 10（范围，1-150）天。CE-TCCS 对双侧 Rosenthal 基底静脉的检出率为 100%，其次是右侧 TS（91.89%）、SS（88.12%）、左侧 TS（74.59%）和Galen 静脉（70.27%）。与磁共振成像/磁共振静脉造影相比，CE-TCCS 对 SS 血栓形成的灵敏度和特异性均为 100%，对右侧 TS 血栓形成的灵敏度和特异性均为 100%，对左侧 TS 血栓形成的灵敏度和特异性均为 100%和 94.4%。总之，CE-TCCS 对脑静脉和窦的识别率较高，对 SS 和 TS 血栓形成的诊断准确性较高。
