- Abstract
BACKGROUND: Strokes are the most common cause of death and the leading cause of acquired disability in adults worldwide. OBJECTIVE: The present study aimed to investigate the value of transcranial Doppler ultrasound (TCD) in the diagnosis of intracranial vascular stenosis in patients with a history of stroke. METHODS: This is a meta-analysis study of diagnostic tests. PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang, and VIP databases were systematically searched. Diagnostic tests using TCD or transcranial colour Doppler ultrasound (TCCD) for detecting intracranial arterial stenosis in patients with a history of stroke were included, with reference standards of intracranial angiography, computed tomography angiography (CTA), or magnetic resonance angiography. The risk bias map was drawn by Revman v5.3, the sensitivity and specificity forest plot was drawn by Stata v16.0, the receiver operating characteristic curve was drawn, and the area under the curve (AUC) was calculated. RESULTS: A total of 812 patients with stroke in 12 studies were included in the meta-analysis. The estimated sensitivity of TCD or TCCD for the detection of intracranial vascular stenosis was 0.77–1.00, and the combined sensitivity was 0.96 (95% confidence interval [CI]: 0.88–0.99); the estimated specificity was 0.32–1.00, and the combined specificity was 0.94 (95% CI: 0.82–0.98); the positive likelihood ratio was 15.8 (95% CI: 5.1–48.6); and the negative likelihood ratio was 0.04 (95% CI: 0.01–0.14). The AUC was 0.99 (95% CI: 0.97–0.99). CONCLUSION: Doppler ultrasound has good consistency with conventional methods for the diagnosis of intracranial artery stenosis in patients with a history of stroke. Different reference standards may affect sensitivity and specificity; when CTA was used as the reference standard, the consistency of the TCD in the diagnosis of intracranial artery stenosis in stroke patients was relatively good.
