自发性低颅压并发颅内静脉窦血栓形成临床分析

目的 自发性低颅压（spontaneous intracranial hypotension，SIH）及颅内静脉窦血栓形成（cerebralvenous thrombosis，CVT）均为神经科少见疾病，而SIH合并CVT更为少见，本研究旨在探寻二者之间有无内在联系。方法 报道2例SIH并发CVT的临床资料，并复习相关文献。结果 2例患者SIH在前，CVT发生在后，同时排除了其他导致静脉窦血栓的危险因素，因此推测SIH也是CVT的危险因素之一。经补液纠正低颅压后，静脉窦血栓也随之好转。结论 SIH可能导致CVT，这一观点也被相关文献所证实。

Clinical Analysis of Cerebral Venous Thrombosis in Spontaneous Intracranial Hypotension

Objective The occurrence of cerebral venous thrombosis （CVT） has been reported rarely among patients with spontaneous intracranial hypotension （SIH）. We reviewed our experience and attempted to establish a causal relationship between these 2 entities. Methods We reported 2 cases in our experience with spontaneous intracranial hypotension and cerebral venous thrombosis and reviewed the relevant literature. Results Clinical or radiographic evidences for SIH preceding CVT were found in 2 patients. There were no other CVT risk factors in 2 cases, except SIH. Therefore we proposed that SIH should be considered as one of risk ~actors of CVT. CVT relieved after the intracranial pressure was corrected. Conclusion Spontaneous intracranial hypotension may result in cerebral venous thrombosis, which is also confirmed by relevant literatures.
