摘要
目的评价脑静脉窦血栓形成（ＣＶＴ）的临床特征及影像诊断。方法详细分析６５例ＣＶＴ患者的临床表现及影像学特征。结果大多数病人表现有头痛、视乳头水肿等颅内压增高征象（９１％）。近半数病人（４９％）伴有局灶神经功能异常如肢体无力、癫痫发作、视力下降等，５１％的病人仅表现为单纯颅内压增高。磁共振成像（ＭＲＩ）和磁共振血管成像（ＭＲＡ）能直接显示脑静脉窦闭塞及其血栓栓子。结论ＭＲＩ和ＭＲＡ对脑静脉窦血栓形成的诊断和随访起重要作用。抗凝、溶栓疗法，及低分子右旋糖酐可能是治疗脑静脉窦血栓形成有效的方法之一。
Objective To investigate the clinical features and imaging diagnosis
of cerebral venous thrombosis. Methods 65 cases of cerebral venous thrombosis(CVT) were
proved by angiography (n=34) or MR(n=44), 30 by both procedures and 6 by pathology as well.
Their age ranged from 13 to 59 years (mean age 32.5), 31 were male and 34 were female.
Results The clinical manifestations were variable, but most patients had symptoms and signs
of intracranial hypertension (91%)such as headache and papilledema. Nearly half of the
patients had focal neurological dysfunction (49%) such as weakness of limbs and seizures
and half of the patients had intracranial hypertension (51%) only. The occluded dural sinus and
the clot could be visualised directly by means of magnetic resonance imaging (MRI) and
magnetic resonance angiography (MRA). 5HZConclusion MRI and MRA are becoming the
imaging investigation of choice for the diagnosis of CVT, Anticoagulation, thrombolysis and
dextran may be effective measures in the treatment of cerebral venous thrombosis.
