Transcranial Doppler assessment of patients with cerebral small vessel disease

BackgroundCerebral small vessel disease (SVD) is associated with acute events such as lacunar and hemorrhagic strokes, or chronic events such as cognitive deficit in the form of subcortical dementia, mood deficit in the form of late onset depression, sphincteric affection, and gait apraxia. Under co...

Description
Summary:BackgroundCerebral small vessel disease (SVD) is associated with acute events such as lacunar and hemorrhagic strokes, or chronic events such as cognitive deficit in the form of subcortical dementia, mood deficit in the form of late onset depression, sphincteric affection, and gait apraxia. Under conditions of moderate blood flow deficit, the inability of sclerotic vessels to dilate due to impairment of the cerebral autoregulation, renders the periventricular white matter seriously ischemic. Therefore, it is important to detect the implications of cerebral large artery disease on the severity of SVD, and the ability of transcranial duplex (TCD) to evaluate it in people at risk.MethodsFifty lacunar stroke patients were recruited, and evaluated using MRI brain to assess SVD score, carotid duplex and TCD to assess extracranial and intracranial stenoses, respectively.ResultsBoth intracranial and extracranial stenoses showed significant relation to the severity of cerebral SVD. Moreover, there were significant relation between intracranial stenosis and presence of lacuna and EPVS.ConclusionCerebral large artery disease contributes to the pathogenesis and severity of cerebral SVD. Therefore, TCD may be a useful tool for the prediction of occurrence of cerebral SVD in high-risk individuals, especially hypertensives.
