“…Compared with magnetic resonance angiography, TCD is cost-efficient and has therefore acquired increased popularity in China. But the accuracy of TCD results depends substantially on personal skills; in fact, the value of TCD in diagnosing intracranial stenosis versus DSA has been validated in our hospital [26,27] , which has shown consistently high correlation. In order to keep a high standard of TCD practice, all ultrasonography examinations in the present study were performed by physicians having at least 5 years of vascular ultrasound experience [28] .…”

Background: Remote ischemic preconditioning (RIPC) of the limb has been shown to induce ischemic tolerance in basic and clinical studies that focused on sustained large artery occlusion rather than small vessel disease (SVD). This study aimed to evaluate the protective effects of brief repetitive limb RIPC on patients with cerebral SVD. Methods: Seventeen patients with cerebral SVD were enrolled. Patients underwent 5 ischemia-reperfusion cycles of preconditioning/sham preconditioning on both upper limbs twice a day for 1 year. Cerebral hemodynamic indexes, brain lesions, cognitive functions and assessment outcomes of dizziness handicap inventory (DHI) were analyzed. Results: In the RIPC group, the mean flow velocity (MFV) of the left middle cerebral artery (MCA) was accelerated (57.33 (52.33-61.34) vs. 51.33 (48.83-58.33), respectively; p = 0.038), and the post-treatment DHI score was reduced (18 (13-19) vs. 34 (21-45), respectively; p = 0.043). The post-treatment volume of the white matter lesions (WMLs) was also reduced (4.19 (2.96-7.25) vs. 6.06 (4.67-10.95), respectively; p = 0.050). There was no remarkable difference between the 2 groups either before or after treatment. Conclusion: The present study indicates that RIPC has potential beneficial effects on cerebral SVD by increasing the MFV of MCA, decreasing the DHI score as well as the volume of WMLs in patients with SVD.

“…The flows in affected vessels correlated with residual diameter and stenosis; the association was more robust with diameter, and only evident with stenosis in the BA but not VAs. However, according to the authors, the distal flow status provides a hemodynamic assessment which, by including collateral capacity, is different from anatomic measures such as stenosis and diameter and, therefore, can be independent of the local hemodynamic impact of the disease [42,43].…”

Managing vertebrobasilar (VB) stroke, particularly basilar artery occlusion (BAO), presents challenges due to diverse clinical presentations and intricate diagnostics, risking delays in acute-phase reperfusion therapies. The diagnostic complexities of VB stroke prompt questions about whether presentation tempo influences outcomes. For non-urgent cases of basilar artery stenosis (BAS) lacking guidelines, clinical management becomes case-dependent. Current options include aggressive medical therapy (AMT) and percutaneous transluminal angioplasty and/or stenting (PTAS). However, the choice of PTAS remains debated, with recent trials observing higher-than-expected recurrence rates, particularly in intracranial stenosis. Understanding hemodynamic status is crucial in predicting stroke risk, especially in atherosclerotic VB disease. Recent studies highlighted the role of distal flow status in predicting stroke risk, emphasizing the importance of hemodynamic assessment beyond anatomic measures. Neurosonology, especially transcranial color-coded duplex sonography (TCCS), emerges as a valuable tool for assessing hemodynamics. Despite TCCS being operator-dependent and technically challenging for BAS evaluation, it effectively detects significant hemodynamic changes, providing real-time information on collateral flow. This review explores the potential role of TCCS in managing BA hemodynamic failure in VB stroke, with particular regard to the selection of BAS patients who may benefit from PTAS.
