The single-phase CTA Clot Burden Score is independently associated with DSA ASITN collateral score.
The single-phase CTA Clot Burden Score is independently associated with DSA ASITN collateral score. The British journal of radiology Lakhani, D. A., Balar, A.

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 DSA based American Society of Interventional and Therapeutic Neuroradiology (ASITN) CS.In this retrospective study, inclusion criteria were as follows: a) Anterior circulation LVO confirmed on CTA from 9/1/2017 to 10/01/2023; b) diagnostic CTA; and c) underwent MT 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?=?0.05 was considered significant.292 consecutive patients (median age?=?68?years; 56.2% female) met our inclusion criteria. CTA CBS and DSA CS showed significant positive correlation (??=?0.51, p??6 has 84.6% sensitivity and 42.3% specificity in predicting good DSA CS.CTA CBS is independently associated with DSA CS and serves as a valuable supplementary tool for collateral status estimation. Further research is necessary to enhance our understanding of the role of CTA CBS in clinical decision-making for patients with AIS-LVO.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.
