Abstract

BACKGROUND AND PURPOSE

Pretreatment CTA-based Cortical Vein Opacification Score (COVES) has been shown to predict good functional outcomes at 90 days in patients with acute ischemic stroke secondary to large vessel occlusion (AIS-LVO). This is thought to be related to its ability to measure collateral status (CS). However, its association with the reference standard test, the DSA-based American Society of Interventional and Therapeutic Neuroradiology (ASITN) collateral score, has yet to be established. Therefore, this study assesses the relationship between COVES and ASITN CS.

MATERIALS AND METHODS

In this prospectively collected, retrospectively reviewed analysis, patients with anterior circulation LVO from September 1, 2017, to October 1, 2023, were included. The COVES grading, which ranges from 0 to 6, was independently assessed by 2 board-certified neuroradiologists. The ASITN CS was independently assessed by a board-certified neuroradiologist and the performing neurointerventionalist. Any discrepancies were resolved through consensus review. Spearman rank correlation, univariable logistic regression, multivariable logistic regression, and receiver operating characteristic curve analysis were performed. A P value of ≤ .05 was considered significant.

RESULTS

In total, 311 consecutive patients (median, IQR = 68 years [59-78 years]; 55.9% women) met our inclusion criteria. There was significant positive correlation between COVES and ASITN CS (ρ = 0.41, P < .001), and higher COVES was significantly and independently associated with good ASITN CS (unadjusted-OR = 1.74, P < .001) and adjusted-OR = 1.73, P < .001). Receiver operating characteristic curve analysis showed area under the curve of 0.71, P < .001).

CONCLUSIONS

By demonstrating the independent association of COVES with the reference standard test for collateral status assessment, the ASITN CS, we further validate the role of COVES in estimating collateral status.

Abstract

BACKGROUND AND PURPOSE

Collateral status is an important predictor of reperfusion and mortality in patients with large vessel anterior circulation acute ischemic stroke (AIS). We assess the utility of multiphase computed tomography angiography (CTA) derived from CT perfusion (CTP) source imaging (dCTA) in determining collateral status compared to the reference standard American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) collateral score on digital subtraction angiography (DSA).

METHODS

We retrospectively analyzed AIS patients treated at our institution from January 9, 2017, to January 10, 2023. Inclusion criteria included CTA-confirmed anterior circulation large vessel occlusion, diagnostic CTP, and mechanical thrombectomy with documented DSA collateral score. The modified treatment in cerebral ischemia score was used to assess reperfusion. Logistic regression analyses evaluated associations between demographic and clinical factors, collateral status, ASITN/SIR, and reperfusion status.

RESULTS

A total of 311 patients (mean age 67.35 ± 16.37, 57.4% female) were included. Univariate analysis showed that proximal M2 (PM2) occlusion site (odds ratio [OR] 4.45, p < 0.001), Alberta Stroke Program Early CT Score (OR 1.24, p = 0.006), dCTA (OR 3.81, p < 0.001), and CTA Tan (OR 6.05, p < 0.001) were associated with an ASITN score of ≥3, indicating collateral flow. Multivariate regression, adjusted for race, occlusion site, radiologic features, National Institutes of Health stroke score, and premorbid modified Rankin score, found PM2 occlusion site (aOR 5.99, p < 0.001), dCTA (adjusted OR [aOR] 2.24, p = 0.04), and CTA Tan (aOR 3.71, p < 0.01) to be significant predictors of ASITN ≥3.

CONCLUSIONS

dCTA is associated with favorable DSA collateral scores and may aid clinical decision-making in AIS patients with large vessel occlusions. Further studies can assess its role in outcome prediction.

Abstract

OBJECTIVES

The variation in quality and quantity of collateral status (CS) is in part responsible for a wide variability in extent of neural damage following acute ischemic stroke from large vessel occlusion (AIS-LVO). Single-phase CTA based clot burden score (CBS) is a promising marker in estimating CS. The aim of this study is to assess the relationship of pretreatment CTA based CBS with the reference standard Digital subtraction angiography (DSA) based American Society of Interventional and Therapeutic Neuroradiology (ASITN) CS.

METHODS

In this retrospective study, inclusion criteria were as follows: (1) Anterior circulation LVO confirmed on CTA from January 9, 2017 to January 10, 2023; (2) diagnostic CTA; and (3) underwent mechanical thrombectomy with documented DSA CS. Spearman's rank correlation analysis, multivariate logistic regression and ROC analysis was performed to assess the correlation of CTA CBS with DSA CS. P ≤ .05 was considered significant.

RESULTS

292 consecutive patients (median age = 68 years; 56.2% female) met our inclusion criteria. CTA CBS and DSA CS showed significant positive correlation (ρ = 0.51, P < .001). On multivariate logistic regression analysis CBS was found to be independently associated with DSA CS (adjusted OR = 1.83, P < .001, 95% CI: 1.54-2.19), after adjusting for age, sex, race, hyperlipidemia, hypertension, diabetes, prior stroke or transient ischemic attack, atrial fibrillation, premorbid mRS, admission NIH stroke scale, and ASPECTS. ROC analysis of CBS in predicting good DSA CS showed AUC of 0.76 (P < .001; 95% CI: 0.68-0.82). CBS threshold of > 6 has 84.6% sensitivity and 42.3% specificity in predicting good DSA CS.

CONCLUSION

CTA CBS is independently associated with DSA CS and serves as a valuable supplementary tool for CS estimation. Further research is necessary to enhance our understanding of the role of CTA CBS in clinical decision-making for patients with AIS-LVO.

ADVANCES IN KNOWLEDGE

CBS by indirectly estimating CS has shown to predict outcomes in AIS-LVO patients. No studies report association of CBS with reference standard DSA. In this study we further establish CBS as an independent marker of CS.

Abstract

BACKGROUND

Collateral status (CS) is an important biomarker of functional outcomes in patients with acute ischemic stroke secondary to large vessel occlusion (AIS-LVO). Pretreatment CT perfusion (CTP) parameters serve as reliable surrogates of collateral status (CS). In this study, we aim to assess the relationship between the relative cerebral blood flow less than 38% (rCBF <38%), with the reference standard American Society of Interventional and Therapeutic Neuroradiology (ASITN) collateral score (CS) on DSA.

METHODS

In this prospectively collected, retrospectively reviewed analysis, inclusion criteria were as follows: (a) CT angiography (CTA) confirmed anterior circulation large vessel occlusion from 9/1/2017 to 10/01/2023; (b) diagnostic CT perfusion; and (c) underwent mechanical thrombectomy with documented ASITN CS. The ratios of the CTP-derived CBF values were calculated by dividing the values of the ischemic lesion by the corresponding values of the contralateral normal region (which were defined as rCBF). Spearman's rank correlation and logistic regression analysis were performed to determine the relationship of rCBF <38% lesion volume with DSA ASITN CS. p ≤ .05 was considered significant.

RESULTS

In total, 223 patients [mean age: 67.77 ± 15.76 years, 56.1% (n = 125) female] met our inclusion criteria. Significant negative correlation was noted between rCBF <38% volume and DSA CS (ρ = -0.37, p < .001). On multivariate logistic regression analysis, rCBF <38% volume was found to be independently associated with worse ASITN CS (unadjusted OR: 3.03, 95% CI: 1.60-5.69, p < .001, and adjusted OR: 2.73, 95% CI: 1.34-5.50, p < .01).

CONCLUSION

Greater volume of tissue with rCBF <38% is independently associated with better DSA CS. rCBF <38% is a useful adjunct tool in collateralization-based prognostication. Future studies are needed to expand our understanding of the role of rCBF <38% within the decision-making in patients with AIS-LVO.
