【摘要】：目的:運(yùn)用3.0T MR技術(shù)評(píng)價(jià)西寧地區(qū)頸動(dòng)脈斑塊患者頸動(dòng)脈狹窄程度及Willis環(huán)代償情況,并探討與腦梗死相關(guān)關(guān)系。方法:收集本院來(lái)自西寧地區(qū)的117例頸動(dòng)脈斑塊患者行頭頸部MRI檢查,分析比較對(duì)照組及腦梗死組兩組間頸動(dòng)脈斑塊情況和顱內(nèi)Willis環(huán)情況。觀察頸動(dòng)脈斑塊部位及狹窄程度、Willis環(huán)具體分型及環(huán)的完整性、各組成血管顯示和變異情況。結(jié)果:1、本研究腦梗死組與對(duì)照組在斑塊發(fā)生部位上無(wú)明顯差異(P0.05),均以頸動(dòng)脈分叉處多見,分別占50%、48.07%。2、頸動(dòng)脈斑塊引起血管不同程度狹窄時(shí),腦梗死組與對(duì)照組存在差異(P0.05)。不同程度狹窄時(shí)觀察顱內(nèi)Willis環(huán)前、后循環(huán)及整環(huán)完整程度無(wú)差異(P0.05)。3、腦梗死組Willis環(huán)變異率80.39%,其整環(huán)、前、后循環(huán)完整率分別為19.61%、62.75%、27.45%,與對(duì)照組均存在差異(P0.05)。4、腦梗死組與對(duì)照組ACA-A1段血管變異率分別為14.70%、6.06%,兩組ACA-A1段變異率存在差異(P0.05)。腦梗死組ACo A顯示率為74.51%,PCo A顯示率為54.90%,與對(duì)照組無(wú)明顯差異(P0.05)。結(jié)論:在頸部動(dòng)脈斑塊患者中,頸動(dòng)脈的不同程度狹窄影響腦梗死的發(fā)生率。頸動(dòng)脈斑塊并發(fā)腦梗死患者Willis環(huán)完整性低,ACo A及PCo A開放代償雖不顯著,但A1段變異率略高。
[Abstract]:Objective: to evaluate the degree of carotid artery stenosis and the compensation of Willis ring in patients with carotid plaque in Xining area by 3.0T Mr technique. Methods: 117 patients with carotid plaque from Xining were examined by MRI. To compare the carotid plaque and intracranial Willis circle between the control group and the cerebral infarction group, and to observe the location of carotid plaque and the degree of stenosis. Results there was no significant difference in the location of plaque between the cerebral infarction group and the control group (P 0.05). Most of them were located at the bifurcation of carotid artery, accounting for 50%, respectively. 48.07.2When carotid plaque caused different degree of stenosis, there was a difference between the cerebral infarction group and the control group (P 0.05). At different degree of stenosis, the intracranial Willis ring was observed. There was no difference in the degree of posterior circulation and global integrity. The variation rate of Willis ring in cerebral infarction group was 80.39. The complete rate of the whole loop, anterior circulation and posterior circulation were 19.61% respectively. There was significant difference between the cerebral infarction group and the control group (P < 0.05). The variation rate of ACA-A1 in cerebral infarction group and control group was 14.70% and 6.06%, respectively. There was a significant difference between the two groups in the variation rate of ACA-A1 segment (P 0.05), and the ACo A display rate in the cerebral infarction group was 74.51% (P < 0.05). The display rate of ACo A was 54.90% in the cerebral infarction group. There was no significant difference between the control group and the control group (P 0.05). Conclusion: in patients with carotid artery plaque. Carotid artery stenosis affected the incidence of cerebral infarction in patients with carotid plaques complicated with cerebral infarction. The low integrity of Willis loop and the open compensations of ACoA and PCo A were not significant in patients with carotid plaques complicated with cerebral infarction. But the variation rate of A1 segment was slightly higher.
