除狭窄程度外,斑块形态学的重要性依然是争论的话题之一。尽管斑块溃疡形成(PU)对考虑颈动脉内膜切除术(CE)极为重要,但仍缺乏足够的证明使人信服。该文对经血管造影有严重狭窄时PU的预后价值做了分析。 按狭窄程度将病人分成中、重度两组,随机对半数病人做了溃疡性斑块移除术。随机双盲法专人对42份造影片的PU做了评估,总准确性88％,K=0.73,对病因危险性做了X~2和t检验。就随访期内PU
In addition to the degree of stenosis, the importance of plaque morphology remains one of the debating topics. Although plaque ulceration (PU) is critically important for the consideration of carotid endarterectomy (CE), there is a lack of sufficient evidence to convince people. This article analyzes the prognostic value of PU in severe angiography. According to the degree of stenosis, the patients were divided into moderate and severe groups, and ulcerative plaque removal was performed on half of the patients randomly. A randomized, double-blinded expert evaluated 42 PU-made PUs with a total accuracy of 88%, K = 0.73, and X ~ 2 and t-tests for the risk of etiology. Follow-up period PU
