【摘要】：目的應用彩色多普勒超聲(CDFI)評估頸內(nèi)動脈顱內(nèi)段重度狹窄及閉塞(ICAO)患者頸動脈結構及血流動力學變化的意義。方法選擇由CDFI和經(jīng)顱多普勒(TCD)聯(lián)合檢測并經(jīng)數(shù)字減影血管造影(DSA)和CT血管成像證實的單側(cè)ICAO患者68例,分別對比雙側(cè)頸總動脈、頸內(nèi)動脈、頸外動脈的內(nèi)徑,收縮期峰值流速(PSV),舒張末期流速(DSV)及血管阻力指數(shù)(RI),比較患側(cè)與健側(cè)的頸總動脈、頸內(nèi)動脈、頸外動脈的血流動力學參數(shù)。結果 68例單側(cè)ICAO患側(cè)頸內(nèi)動脈內(nèi)徑低于健側(cè)(P0.05),患側(cè)頸總動脈、頸外動脈內(nèi)徑與健側(cè)差異無統(tǒng)計學意義(P0.05),患側(cè)頸總動脈、頸內(nèi)動脈PSV、DSV均低于健側(cè),RI高于健側(cè),差異均有統(tǒng)計學意義(P0.05);頸外動脈PSV、DSV均高于健側(cè),RI低于健側(cè),差異有統(tǒng)計學意義(P0.05)。眼動脈(OA)分支前患側(cè)頸內(nèi)動脈PSV、DSV低于OA后(P0.05),RI高于OA分支閉塞后(P0.05)。結論CDFI可用于ICAO的初步定位評估。
[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.
