【摘要】：目的应用彩色多普勒超声(CDFI)评估颈内动脉颅内段重度狭窄及闭塞(ICAO)患者颈动脉结构及血流动力学变化的意义。方法选择由CDFI和经颅多普勒(TCD)联合检测并经数字减影血管造影(DSA)和CT血管成像证实的单侧ICAO患者68例,分别对比双侧颈总动脉、颈内动脉、颈外动脉的内径,收缩期峰值流速(PSV),舒张末期流速(DSV)及血管阻力指数(RI),比较患侧与健侧的颈总动脉、颈内动脉、颈外动脉的血流动力学参数。结果 68例单侧ICAO患侧颈内动脉内径低于健侧(P0.05),患侧颈总动脉、颈外动脉内径与健侧差异无统计学意义(P0.05),患侧颈总动脉、颈内动脉PSV、DSV均低于健侧,RI高于健侧,差异均有统计学意义(P0.05);颈外动脉PSV、DSV均高于健侧,RI低于健侧,差异有统计学意义(P0.05)。眼动脉(OA)分支前患侧颈内动脉PSV、DSV低于OA后(P0.05),RI高于OA分支闭塞后(P0.05)。结论CDFI可用于ICAO的初步定位评估。
[Abstract]:Objective to evaluate the changes of carotid artery structure and hemodynamics in patients with severe intracranial stenosis and occlusion of internal carotid artery by color Doppler ultrasonography (CDFI). Methods Sixty-eight patients with unilateral ICAO, confirmed by digital subtraction angiography (DSA) and CT angiography, were selected to compare the internal diameters of bilateral common carotid artery, internal carotid artery and external carotid artery, respectively, which were detected by CDFI and transcranial Doppler imaging (TCD) and confirmed by digital subtraction angiography (DSA) and CT angiography. Peak systolic velocity (PSV), end-diastolic flow velocity (DSVV) and vascular resistance index (RI) were compared between the common carotid artery, the internal carotid artery and the external carotid artery in the affected side and the normal side. The hemodynamic parameters of the common carotid artery, the internal carotid artery and the external carotid artery were compared between the affected side and the normal side. Results the internal diameter of internal carotid artery in 68 patients with unilateral ICAO was lower than that of healthy side (P 0.05). There was no significant difference in internal diameter of common carotid artery and external carotid artery between the affected side and the healthy side. The internal diameter of the common carotid artery and internal carotid artery of the affected side were lower than that of the healthy side. The RI of the common carotid artery and the internal carotid artery were lower than that of the healthy side. The difference was statistically significant (P 0.05), and the PSVV DSV of the external carotid artery was higher than that of the healthy side (P 0.05), and the RI of the normal side was lower than that of the normal side (P 0.05). The PSV DSV of the internal carotid artery in the affected side before OAA was lower than that in the OA group (P 0.05) and the RI was higher than that in the OA branch after occlusion (P 0.05). Conclusion CDFI can be used to evaluate the localization of ICAO.
