【摘要】 目的探讨产后颅内静脉窦血栓形成的发病机制、临床表现、影像学特点、诊断、鉴别诊断以及治疗。方法回顾性分析6例已确诊的产后颅内静脉窦血栓形成患者的临床与影像资料。结果6例患者临床均以亚急性高颅压症状为主,以上矢状窦血栓形成多见,在轴位T2WI上,窦腔内可见长T2高信号影,在矢状位T1WI上,窦腔内可见短T1高信号影。结论对于有妊娠和分娩史,不明原因出现颅内压增高、局限性神经症状、突然意识障碍的患者,须行头MRI或DSA检查。更多还原

【Abstract】 Objective To study the etiopathogenisis, clinical situation, imaging feature, diagnosis, differential diagnosis and treatment of postpartum cranial venous sinus thrombosis(PCVST). Methods Clinical and imaging data of 6 cases with clinically diagnosed PCVST were retrospectively analyzed. Results 6 cases were mainly characterized by subacute intracranial hypertension.superior sagittal sinus thromboses were seen frequently in the imaging.On coronal T2WI,the lesion in sinus was long T2 hyperintense,on sagittal T1WI,the lesion in sinus was short T1 hyperintense. Conclusion MRI or DSA must be practiced in woemen with history of pregnancy and delivery, unkownly appearing intracranial hypertension,local neurological symptoms and conscious disturbance. [更多还原
