【摘要】：目的:探讨彩色多普血流显像(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)联合检测单侧ICAO患者72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:患侧颈内动脉内径、颈总动脉和颈内动脉显著低于健侧,而患侧颈外动脉高于健侧;患侧颈总动脉、颈内动脉和颈外动脉的RI显著低于健侧的。患侧眼动脉(OA)分支前颈内动脉PSV明显低于OA分支闭塞后的;患侧眼动脉(OA)分支前颈内动脉RI显著高于OA分支闭塞后的。结论:CDFI可对颈内ICAO作出初步定位评估。
[Abstract]:Objective: to evaluate the significance of color Doppler flow imaging (CDFI) in evaluating carotid artery structure and hemodynamics in patients with severe intracranial stenosis and occlusion (ICAO). Methods: the internal diameters of bilateral common carotid artery, internal carotid artery and external carotid artery were measured by CDFI and transcranial Doppler (TCD) in 72 patients with unilateral ICAO. Peak systolic velocity (PSV) end-diastolic velocity (DSV) and vascular resistance index (RI) were compared to compare the hemodynamic parameters of common carotid artery internal carotid artery and external carotid artery between the affected side and the normal side. Results: the internal diameter of the internal carotid artery, the common carotid artery and the internal carotid artery were significantly lower than those of the healthy side, while the external carotid artery of the affected side was higher than the healthy side, and the RI of the common carotid artery, the internal carotid artery and the external carotid artery of the affected side was significantly lower than that of the healthy side. The PSV of the anterior carotid artery of the affected ophthalmic artery (OA) was significantly lower than that of the occlusion of the OA branch, and the RI of the anterior carotid artery of the affected ophthalmic artery (OA) was significantly higher than that of the occlusion of the OA branch. Conclusion the preliminary localization of ICAO in the neck can be evaluated by CDFI.
