Eur J Radiol 2023; 165:110894. [PMID: 37290362 DOI: 10.1016/j.ejrad.2023.110894] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 05/19/2023] [Accepted: 05/23/2023] [Indexed: 06/10/2023]
Abstract
PURPOSE Post-irradiated carotid stenosis (PIRCS) commonly occurs in patients with nasopharyngeal cancer (NPC) after receiving radiotherapy. A high in-stent restenosis (ISR) is observed in these patients after percutaneous transluminal angioplasty and stenting (PTAS) for PIRCS. Risk factors for ISR in these patients remain unclear. METHODS Data were retrospectively analyzed from 68 NPC patients with 70 lesions treated with PTAS for PIRCS. The median follow-up was 40 months (range: 4-120). Evaluations of demographic and clinical characteristics included stenotic severity, stenotic lesion length (SLL), stenotic lesion location, and ISR-related stroke during follow-up. The risk for ISR was evaluated using multiple Cox regression analysis. RESULTS The median age of the patients was 61 (35-80) years and 94.1% were male. The median stenosis was 80% (60-99%) and the median SLL was 2.6 cm (0.6-12.0 cm) before PTAS. Compared to those without ISR, patients with longer SLL were at significantly greater risk of developing significant ISR, defined as > 50% after PTAS (hazard ratio [HR] and 95% confidence interval [CI]: 2.06 [1.30-3.28]). PTAS for lesions from the internal carotid artery (ICA) to common carotid artery (CCA) was associated with a significantly greater risk of ISR than lesions located only in the ICA (HR: 9.58 [1.79-51.34]). The baseline cut-off value for SLL that best predicted significant ISR was 1.6 cm (area under the curve 0.700, sensitivity 83.3% and specificity 62.5%). CONCLUSION Stenotic lesions located from the ICA to CCA with longer SLL at baseline appear to predict ISR in NPC patients with PIRCS after PTAS. Intensive post-procedural follow-up is advised for this patient population.

Int J Clin Pract 2022; 2022:5191581. [PMID: 36304978 PMCID: PMC9578805 DOI: 10.1155/2022/5191581] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2022] [Revised: 07/18/2022] [Accepted: 08/09/2022] [Indexed: 11/22/2022] Open
Abstract
The aim of this study is to evaluate the value of the triglyceride-glucose (TyG) index and the risk of large artery atherosclerotic (LAA) stroke. Information on general demographic and clinical characteristics, magnetic resonance angiography (MRA) examination, and blood biochemical index determination were obtained. Based on age stratification, three models to evaluate the odds ratio (OR) and the 95% confidence interval (95% CI) were employed to determine the correlation between the TyG index and the risk of LAA stroke. The most effective TyG index threshold in predicting a high risk of LAA stroke was identified using receiver operating characteristic (ROC) curve analysis. Logistic regression verified the association between the risk of LAA stroke and the TyG index. Both with and without age stratification, logistic regression analysis showed that the TyG index was a significant predictor of the occurrence of LAA stroke (P < 0.05). The maximum Youden index for determining a high risk of LAA stroke was found at a TyG index of 4.60. The area under the ROC curve was 0.69 (95% CI: 0.646-0.742, P < 0.05), sensitivity was 78.0%, and specificity was 63.4%. An elevated TyG index was remarkably associated with a high risk of LAA stroke.

Can intracranial time-of-flight-MR angiography predict extracranial carotid artery stenosis? J Neurol 2021; 269:2743-2749. [PMID: 34750675 PMCID: PMC9021057 DOI: 10.1007/s00415-021-10876-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 10/24/2021] [Accepted: 10/25/2021] [Indexed: 01/22/2023]
Abstract
OBJECTIVES Extracranial stenosis of the internal carotid artery (ICA) is an important cause of ischemic stroke and transient ischemic attack (TIA). It can be diagnosed using contrast-enhanced CT or MR angiography (MRA) as well as Doppler ultrasound. In this study, we assessed the diagnostic value of intracranial time-of-flight (TOF) MRA to predict extracranial ICA stenosis (ICAS). METHODS We retrospectively analyzed consecutive patients with acute ischemic stroke or TIA and middle- (50-69%) or high-grade (70-99%) unilateral extracranial ICAS according to NASCET criteria assessed by ultrasound between January 2016 and August 2018. The control group consisted of patients without extracranial ICAS. Intraluminal signal intensities (SI) of the intracranial ICA on the side of the extracranial stenosis were compared to the contralesional side on TOF-MRA source images. SI ratios (SIR) of contralesional:lesional side were compared between groups. RESULTS In total, 151 patients were included in the main analysis. Contralesional:lesional SIR in the intracranial C4-segment was significantly higher in patients with ipsilateral extracranial ICA stenosis (n = 51, median 74 years, 57% male) compared to the control group (n = 100, median 68 years, 48% male). Mean SIR was 1.463 vs. 1.035 (p < 0.001) for right-sided stenosis and 1.362 vs. 1.000 (p < 0.001) for left-sided stenosis. Receiver-operating characteristic curve demonstrated a cut-off value of 1.086 for right-sided [sensitivity/specificity 75%/81%; area under the curve (AUC) 0.81] and 1.104 for left-sided stenosis (sensitivity/specificity 70%/84%; AUC 0.80) in C4 as a good predictor for high-grade extracranial ICAS. CONCLUSIONS SIR on TOF-MRA can be a marker of extracranial ICAS.
