Background and purpose The prognostic value of contrast accumulation from non‐contrast brain computed tomography taken immediately after endovascular reperfusion treatment in acute ischaemic stroke patients to predict symptomatic hemorrhage was studied. Methods Between July 2007 August 2014, anterior circulation who were treated by intra‐arterial thrombolysis or thrombectomy included. Contrast defined as a high attenuation area treatment, categorized into three groups according the presence location contrast: (i) negative, (ii) cortical involvement (iii) non‐cortical involvement. rates 24 h functional outcome at discharge compared between with without Results Of 64 intervention, detected 56, including 33 23 pattern more frequently associated (13 vs. 1 patient, P = 0.003) grave modified Rankin Scale 5 6 (14 4, 0.048) than group. Multivariate logistic regression analysis initial collateral status occlusion site disclosed that independently predicted (odds ratio 19.0, confidence interval 1.6–227.6, 0.020). Conclusion Our study provides evidence is treatment.
