摘要
目的分析颈内动脉严重狭窄或闭塞时,侧支循环开放与临床的关系。方法选择经颅多普勒超声检测颈内动脉严重狭窄或闭塞、再经数字减影血管造影检查证实的患者86例,根据侧支循环开放情况分为4组:前交通、后交通和眼动脉侧支循环开放组(Ⅰ组)1 7例,前交通或后交通动脉侧支循环开放组(Ⅱ组)27例,眼动脉侧支循环开放组(Ⅲ组)28例,无侧支循环开放组(Ⅳ组)14例。分析各组患者侧支循环开放情况并进行比较。结果 86例患者共检出阳性侧支循环1 39条,前交通动脉侧支循环开放57条,占41.0%,后交通动脉开放32条.占23.0%,眼动脉开放50条,占36.0%。前交通动脉及后交通动脉侧支循环开放较眼动脉侧支循环开放症状轻且预后好。结论经颅多普勒超声对颈内动脉狭窄或闭塞患者颅内侧支循环的判断有良好的敏感性和特异性.侧支循环的开放情况与临床缺血性病变及预后关系密切,侧支循环的评判有重要的临床意义。
Objective To analyze the relationship between opening of the collateral circulation and clinical manifestations during stenosis or occlusion of internal carotid artery. Methods Eighty-six patients with stenosis or occlusion of internal carotid artery detected by transcranial Doppler （TCD） and checked by digital subtraction angiography were selected. The patients were divided into four groups according to the opening situation of the collateral circulation：the group of opening 3 collateral circulation（Group 1）, the group of opening anterior or posterior communicating collateral circulation （Group 2）, the group of opening ophthalmic artery collateral circulation （Group 3）, the group of no collateral circulation opening（Group 4）. The situation of opening of collateral circulation in each group was analyzed and compared. Results Compared with the symptoms of opening collateral circulation of ophthalmic artery, the symptoms of opening anterior communicating artery and posterior communicating artery were milder and prognosis was better. Conclusion TCD measures the collateral circulation of stenosis or occlusion of internal carotid artery sensitively and specifically. The situation of opening of collateral circulation is closely related with prognosis. The evaluation of collateral circulation has important clinical significance.
