【摘要】：目的分析35例脑静脉窦血栓患者的临床资料及CT、MRI影像学特征,结合文献复习,旨在提高对脑静脉窦血栓的认识,从而早期诊断指导临床及时治疗。方法回顾性分析静脉窦血栓患者的病史,结合患者的临床表现、发病起因,对常规头颅CT及MRI平扫、增强扫描、磁共振静脉血管成像、磁敏感加权成像表现进行系统的归纳分析,总结静脉窦血栓的影像学特征。结果 35例脑静脉窦血栓患者共45处血栓形成,其中上矢状窦血栓形成17处(37.8%),左侧横窦血栓形成6处(13.3%),右侧横窦血栓形成8处(17.8%),左侧乙状窦血栓形成4处(8.9%),右侧乙状窦血栓形成5处(11.1%),直窦血栓形成5处(11.1%)。28例可观察到血栓的直接征象,间接征象包括静脉淤血性脑梗死(24例),出血(8例),磁敏感加权成像上较其他序列更易发现脑内出血灶,磁共振静脉血管成像可见皮层浅静脉增粗、增多;增强扫描可见静脉窦血栓处呈"空三角征"。结论联合应用不同的影像技术可提高对脑静脉窦血栓诊断的准确性,从而指导脑静脉窦血栓的早期诊断及早期治疗,减少病死率、病残率及后遗症的发生。
[Abstract]:Objective to analyze the clinical data and MRI imaging features of 35 patients with cerebral venous sinus thrombosis, and to improve the understanding of cerebral venous sinus thrombosis. Methods the history of the patients with venous sinus thrombosis was analyzed retrospectively. Combined with the clinical manifestations and the causes of the disease, conventional CT and MRI plain scan, enhanced scan, magnetic resonance venous angiography were performed on routine cranial CT and MRI. The imaging features of venous sinus thrombosis in 35 patients with cerebral venous sinus thrombosis were summarized and analyzed systematically. Results there were 45 thrombosis sites in 35 patients with cerebral venous sinus thrombosis. 17 superior sagittal sinus thrombosis, 6 left transverse sinus thrombosis, 8 right transverse sinus thrombosis, 8 right transverse sinus thrombosis, 4 left sigmoid sinus thrombosis, 5 right sigmoid sinus thrombosis, 5 right sigmoid sinus thrombosis, 5 right sigmoid sinus thrombosis, and 5 straight sinus thrombosis. Observing direct signs of thrombosis, Indirect signs included 24 cases of venous congestion cerebral infarction and 8 cases of hemorrhage. Magnetic sensitivity weighted imaging was easier than other sequences to find intracerebral hemorrhage foci. Magnetic resonance venography showed that the superficial cortical veins were thicker and increased. Conclusion the combined use of different imaging techniques can improve the accuracy of diagnosis of cerebral venous sinus thrombosis, so as to guide the early diagnosis and treatment of cerebral venous sinus thrombosis and reduce the mortality. Disability rate and sequelae.
