Exploration the diagnosis and the cause of clinical misdiagnosis on superior sagittal sinus thrombosis

目的 :探讨上矢状窦血栓形成 (SSST)的诊断及临床误诊原因。方法 :对 14例SSST的临床资料及临床误诊原因进行分析。结果 :进行性头痛为SSST最常见的临床表现 ,临床症状缺乏特异性、部分患者原因不明及不能恰当地分析CT所见 (大脑皮层静脉血栓形成所导致的出血、梗塞、脑水肿 )是产生误诊的重要原因。结论 :对进行性颅内压增高应高度怀疑 ,CT和MRI是诊断SSST有效手段 ,脑血管造影诊断价值最大。

Objective: To explore the diagnosis and the cause of clinical misdiagnosis on superior sagittal sinus thrombosis (SSST). Methods: The clinical data and cause of misdiagnosis were analysed in 14 patients with SSST . Results :Progressive headache was the most common clinical manifestations . there were some important causes resulting in misdiagnosis , Such as , The clinical symptom lacked characteristics , The cause in some patients was unknow and we couldn't proper analyse the CT showings (cerebral cortical vein thrombosis resulted in hemorrhage infarction and wet brain) . Conclusion:It should be highly suspected that the progressive intracranial hypertension . CT and MRI were the effective methods for diagnosis of SSST , but DSA was most significant .
