无创性经颅多普勒(TCD)超声检查颅内动脉血流值可以发现临床上无症状的脑血栓形成。业已证明有症状的高度(≥70％)颈内动脉(ICA)狭窄高发脑微血栓,有ICA疾患的病人无症状性微血栓形成可能是卒中的危险因素,作者分析了高度ICA狭窄时有症状及无症状情况下脑微血栓发生率的差异。
Non-invasive transcranial Doppler (TCD) ultrasound examination of intracranial arterial blood flow values can be clinically asymptomatic cerebral thrombosis. It has been demonstrated that asymptomatic micro-thrombosis in symptomatic height (≥70%) ICA stenosis in patients with ICA disorders may be a risk factor for stroke. The authors analyzed the presence of symptomatic And the incidence of cerebral micro-thrombosis in asymptomatic cases.
