放射性核素脑血流显像用于一侧颈动脉切除术后病人脑血流检测

Radionuclide Cerebral Angiography after Contra-lateral Carotid Artery Resection

利用放射性核素脑血流显像的方法对“不行血管重建的一侧颈动脉切除术”病人脑血流分布进行研究，结果表明：当一侧颈动脉切除后，患侧颈血流减少，但脑血流显示出与同侧基本保持一致，同时可观察到其机体代偿途径有如下３种：①伴行椎动脉扩张，②同侧代偿；③对侧代偿。有关机体代偿的详细途径尚需进一步研究。

Cerebral blood flow was studied by radionuclide angiography in 7 patients after unilateral unilateral carotid artery resection. The results indicated that the cerebral blood distribution was in balance on both side after either one of carotid artery was resected as a result of three compensatory paths:namely:(1)Dilatation of the homotaleral vertebral artery,(2)Ipsilateral arterial enhancemnt,(3)Contralateral arterial compensation.Further investigations are warranted for the arterial compensation.
