RESUMO
Objective To explore the value of microvascular angiography in evaluating the neovascularization of internal carotid artery plaque and the prediction of cerebral infarction.Methods A total of 100 patients with suspected cerebral infarction received from March 19th,2016 to December 1 st,2017 in our hospital were enrolled in this study.All patients underwent microvascular imaging and then analyzed the importance of this technique in evaluating cerebral infarction,plaque neovascularization.Results 100 lesions were recorded in 100 patients,among which there were 22 cases with no superb microvascular ultrasound imaging (SMI) and blood flow signal (ie,score 0) in the plaque.SMI imaging could better show neovascularization (ie score 1 or 2 points).In 78 cases,they all grew from the arterial wall to the plaque.There were 61 cases of cerebral infarction in the blood flow group (78.2％),8 cases (36.3％) of cerebral infarction in the group without blood flow,with statistical significance(P =0.023).SMI imaging was highly sensitive to the prediction of cerebral infarction incidence,reaching 88.4％.Conclusions Ultra-microvascular imaging can improve the sensitivity of cerebral infarction prediction and promptly detect neovascularization of internal carotid artery plaque,thus providing a basis for clinical treatment.
