目的:探讨脑静脉及静脉窦血栓形成(CVST)的病因及临床特点。方法:回顾性调查16例CVST患者的临床资料。结果:侧窦血栓(87.5%)和上矢状窦血栓形成(37.5%)最常见,70%患者有2个以上部位血栓形成。最常见的症状为头痛14例(87.5%),其次为癫癎、偏瘫、嗜睡及反应迟钝等。头颅CT有14例(87.5%)发现特征性改变,为枕部近颅板下或后纵裂条索状高密度影。头颅MRI结合MRV阳性率为94%。结论:头痛是CVST患者最常见的主诉,CT可作为一种诊断CVST有效的初始检查,MRI结合MRV有诊断价值。
Objective: To explore the etiology and clinical features of cerebral venous and sinus thrombosis (CVST). Methods: The clinical data of 16 patients with CVST were retrospectively investigated. RESULTS: The most common form of lateral sinus thrombus (87.5%) and superior sagittal sinus thrombosis (37.5%) was thrombus formation in more than 70% of patients. The most common symptoms were headache in 14 cases (87.5%), followed by epilepsy, hemiplegia, lethargy and unresponsiveness. 14 cases (87.5%) of cranial CT found characteristic changes for the occipital suboccipital or posterior longitudinal fissure cord-like high density. Head MRI and MRV positive rate was 94%. Conclusion: Headache is the most common complaint of patients with CVST. CT can be used as an effective initial diagnosis of CVST. MRI combined with MRV has diagnostic value.
