Abstract

Changes of regional cortical blood flow (rCBF) was monitored by the heat clearance method during the operation of cervical carotid ligation combined with superficial temporal artery and middle cerebral artery anastomosis for the treatment of inaccessible aneurysms of the internal carotid artery in eight patients. There were three types of rCBF responses upon closure of the internal carotid artery, with or without bypass blood flow. Based on the responses, the internal carotid artery was ligated abruptly or occluded gradually. The usefulness of the method for monitoring cerebral ischaemia for therapeutic carotid ligation is discussed.

摘要

采用热清除法监测了8例因颈内动脉近端动脉瘤难以夹闭而施行颈总动脉结扎并颞浅动脉-大脑中动脉吻合术患者术中局部脑血流量(rCBF)的变化。在阻断颈内动脉血流(无论有无旁路血流)时,rCBF反应有3种类型。根据这些反应,对颈内动脉进行了一次性结扎或逐步闭塞。文中讨论了该方法在治疗性颈动脉结扎术中监测脑缺血的实用性。
