【摘要】:目的分析Stanford A型主動脈夾層(AD)累及頸動脈時對血流的影響,為探討A型主動脈夾層與腦梗死的相關性提供參考依據。方法連續(xù)收集急診超聲診斷并經CT血管造影術(CTA)確診的41例急性Stanford A型主動脈夾層患者,分為夾層未累及頸動脈組(A組,n=20)和累及頸動脈組(B組,n=21),分析兩組頸動脈頻譜及血流量差異并比較腦梗死發(fā)生率及病死率。結果 Stanford A型AD患者頭臂血管累及率高達51.20%。A、B兩組間的頸動脈頻譜形態(tài)和血流量間差異有統(tǒng)計學意義(P0.05),B組中頻譜形態(tài)異常者明顯高于A組(P0.05),雙側頸內動脈(ICA)和椎動脈(VA)血流量比較,B組明顯低于A組(P0.05);比較兩組間新發(fā)腦梗死發(fā)生率(20.00%vs 42.86%,P=0.115 9)、病死率(20.00%vs 38.10%,P=0.203 1)無統(tǒng)計學差異。結論 Stanford A型夾層頭臂血管累及率高,雖然腦梗死發(fā)生率和病死率未顯示明顯差別,但累及頸動脈時頻譜形態(tài)及入顱血流量明顯受到影響,應及時對急性A型主動脈夾層患者頸動脈進行評估,為主動脈夾層患者腦梗死防治及改善預后提供重要依據。
[Abstract]:Objective To analyze the influence of Stanford type A aortic dissection (AD) on blood flow in patients with carotid artery involvement, and to provide reference for exploring the correlation between type A aortic dissection and cerebral infarction. The frequency spectrum and blood flow of carotid artery in group A (n=20) and group B (n=21) were analyzed and the incidence and mortality of cerebral infarction were compared. Compared with group A (P 0.05), the blood flow of bilateral internal carotid artery (ICA) and vertebral artery (VA) in group B was significantly lower than that in group A (P 0.05), and the incidence of new cerebral infarction (20.00% vs 42.86%, P = 0.1159) and mortality (20.00% vs 38.10%, P = 0.2031) were not significantly different between the two groups. The incidence and mortality of acute type A aortic dissection were not significantly different, but the frequency spectrum and blood flow were significantly affected when the carotid artery was involved.
