脑动脉瘤手术前后经颅多普勒超声检测的初步研究

A Preliminary Study of Transcranial Doppler Ultrasonography for Cerebral Aneurysms in Pre-and Post-operative periods

经颅多普勒超声检测18例脑动脉瘤患者于手术前后脑血流的变化。结果提示，经颅多普勒超声对判断有无血管痉挛是一种有实用价值的非损伤性检测手段，对于选择破裂脑动脉瘤早期手术的适应证也是一个重要依据，并可估价阻断颈动脉后，颅内侧支循环及病人耐受力的状况。

Velocities of cerebral arterial blood flow were measured by Transcranial Doppler ultrasound (TCD) in eighteen patients with cerebral aneurysms before and after operations. It indicates that TCD is a useful non-invasive monitoring method in judging wether vasospasm is present or not, besides its important index of operative indication for the ruptured cerebral aneurysms in early stage, it can also provide a dynamic guide in the assessment of the efficient intracranial collateral flow follwing carotid occlusion, that the patient is albe to tolerate.
