By using measurements of cerebral blood flow and internal carotid artery pressure it is possible to select patients in whom carotid ligation can be performed with a very low risk of post-operative cerebral ischaemia. A study has been carried out in 100 patients comparing this method with clinical predictions of the type used in aneurysm surgery based on age of the patient, arterial hypertension, time from latest subarachnoid haemorrhage, and neurological status on a modified Botterell scale. These clinical factors were found to be of little value in predicting which patients would and would not develop cerebral ischaemia after carotid occlusion.
通过测量脑血流量和颈内动脉压力,可以挑选出那些进行颈动脉结扎术后发生脑缺血风险极低的患者。对100名患者进行了一项研究,将这种方法与动脉瘤手术中基于患者年龄、动脉高血压、距最近蛛网膜下腔出血的时间以及改良的博特雷尔量表评估的神经学状态所采用的临床预测方法进行比较。结果发现,这些临床因素在预测哪些患者在颈动脉闭塞后会发生或不会发生脑缺血方面价值不大。
