摘要目的 探讨颈总动脉闭塞性病变的侧支血流代偿分型及其特点. 方法 回顾性收集齐齐哈尔医学院附属第二医院脑血管狭窄诊断与介入治疗中心自2016年5月至2018年9月诊治的20例颈总动脉闭塞性病变患者的血流动力学及影像学资料,依据患者有无颈内动脉窃血及侧支循环对其侧支血流代偿进行分型. 结果 20例患者中11例存在颈内动脉窃血;17例存在侧支循环,其中前交通动脉侧支10支,后交通动脉侧支9支,大脑后动脉-大脑中动脉软脑膜吻合侧支11支,眼动脉侧支8支.患者的侧支血流代偿分型可分为3型,其中Ⅰ型为单纯颈内动脉窃血,共3例;Ⅱ型为颈内动脉窃血+侧支循环,共8例;Ⅲ型为单纯侧支循环,共9例. 结论 部分颈总动脉闭塞性病变患者的侧支血流代偿中存在颈内动脉窃血途径.

abstractsObjective To explore the classification of collateral blood compensation pathways and collateral blood compensation characteristics in patients with common carotid artery occlusive disease.Methods The hemodynamie and imaging data of 20 patients with common carotid artery occlusive disease,admitted to our hospital from May 2016 to September 2018,were collected.The patients were classified according to whether they had internal carotid artery stealing and collateral circulation compensating for collateral flow.Results Internal carotid artery hematoma was found in 11 of the 20 patients;there was collateral circulation in 17 patients,including 10 branches of the anterior communicating artery,9 branches of the posterior communicating artery,11 branches of the posterior cerebral artery-middle cerebral arterial pia anastomosis,and 8 branches of the ocular artery.There were three types of collateral blood compensation pathways to be discovered in the 20 patients with common carotid artery occlusive disease;type Ⅰ (n=3) was the collateral blood compensation pathway with simple internal carotid artery stealing,type Ⅱ (n=8) was the collateral blood compensation pathway with internal carotid artery stealing and collateral circulation,and type Ⅲ (n=9) was the collateral blood compensation pathways with simple collateral circulation.Conclusion In some patients with common carotid artery occlusion,the internal carotid artery stealing route exists in the collateral flow compensation.
