颅内静脉窦血栓形成与磁共振及血管造影分析研究

目的探讨颅内静脉窦血栓形成（CVST）的临床特点,磁共振成像（MRI）、磁共振血管造影（MRA）及数字减影血管造影（DSA）对其诊断的价值及早期诊断、早期治疗的意义。方法总结64例经MRI、MRA、确诊为颅内静脉窦血栓形成的住院和急诊病人的临床资料及影像学特点。结果 30例病人无明确病因,发病时间4~9年,主要临床表现有颅内压增高及皮质受损表现。62例病人经MRI、MRA确诊,未确诊2例经DSA检查确诊。本组32例发病〈1个月的病人经静脉窦插管溶栓术及抗凝等治疗,症状和体征完全恢复或明显好转。本组28例行静脉窦插管溶栓术,20例病人症状和体征完全恢复。结论 CVST临床表现无特异性,MRI、MRA及DSA检查可确诊。发病早期（〈1个月）给予静脉窦插管溶栓术,症状和体征完全恢复几率大,临床上值得推广。
