摘要 应用经颅超声多普勒研究15例经脑血管造影证实的脑动脉瘤破裂出血患者的脑循环动态改变。12例出现不同程度的血管痉挛,以出血侧大脑中动脉为主,8~14天达高峰。此12例均行手术夹闭动脉瘤,术前1~3天血流速度在81~130CM/S,预后好。余3例表现严重颅内压升高和脑部低灌注的患者未行手术,均死亡。表明经颅多普勒能及时发现血管痉挛,同时反映颅内压和脑灌注的变化,对选择手术时机和判断临床预后有重要意义。 AbstractTranscranial Doppler ultrasound(TCD)was used to study the serial changes of cerebral cir-culation in 15 patients with hemorrhage after aneurysmal rupture.A marked increase of flow ve-locity of the middle cerebral artery was found in 12 operated patients within 8~ 14 days after on-set.Velocities reached maximum value about 200 cm/s,and then declined.The patients whosemean flow velocity was 84~130 cm/s before operation had good prognosis.Increased intracra-nial pressure and cerebral hypoperfusion were observed in three patients by TCD,and they died in two weeks.The results indicate that TCD is a reliable and convenient noninvasive method for mon-itoring the change of cerebral vasocpasm,intracranial pressure and cerebral blood perfusion,which provides important clinical in formation concerning choice of the time of operation and clinical prognosis.
