“…Modification of regular computed tomography angiogram and contrast enhanced trans cranial Doppler (CE-TCD) is found to be useful for intracranial stenosis evaluation, 5,6 a case report of utility of CE-TCD in intracranial stent evaluation also been described. 7 Though the utility of TOF-MRA and CE-MRA in in-stent stenosis has been described, accuracy of each modality was not been evaluated in detail. In a recent study of various MRA techniques for the evaluation of in-stent flow, CE-MRA showed better flow signals.…”

Noninvasive imaging modalities are being used for long-term follow-up of intracranial stented patients of nonatherosclerotic etiology. The aim of this study is to determine the utility of contrast-enhanced magnetic resonance angiography (CE-MRA) source images in delayed intracranial in-stent stenosis. A total of 18 stented patients for nonatherosclerotic etiology were reviewed; all had follow-up digital subtraction angiography (DSA) and CE- and time-of-flight (TOF)-MRA. Four sets of MR images (TOF-MRA reformatted images, TOF-MRA source images, CE-MRA reformatted images, and CE-MRA source images) were reviewed for detection of ≥ 50% stenosis. Accuracy of each image set was calculated comparing to DSA. Overall delayed in-stent stenosis during follow-up DSA was 10%. The sensitivity of TOF reformatted image, TOF source image, CE-MRA reformatted image, CE-MRA source image are 33% (6/18), 55.6% (10/18), 77.8% (14/18), and 100% (18/18), respectively, while negative predictive value are 14.3% (2/14), 20% (2/10), 33% (2/6), and 100% (2/2), respectively. CE-MRA source images are equally efficacious as DSA to detect significant (≥ 50%) delayed in-stent stenosis.

“…Therefore, TCCS is a suitable tool for assessing IVAS and performing follow-up for interventional therapy. However, only a few case reports have addressed the application of TCCS in cerebral arterial stenting (Oehm et al 2002;Vicenzini et al 2007). In 2013, the results of a 2-y follow-up on middle cerebral artery stenting were reported by Wang et al (2013).…”

“…Pade et al demonstrated that a complete visualization of BA was feasible by using combined transforaminal and transtemporal approach [71]. Some studies found that the validity of TCD in the assessment of the degree of BA stenosis or in-stent restenosis was poor, whereas TCCS exhibited excellent sensitivity and specificity in detecting in-stent BAS [50,72,73]. Nasr et al showed that TCCS allowed to detect symptomatic steno-occlusive lesions of the large intracranial arteries with perfect agreement with MR 3D TOF angiography.…”

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.
