  • Description: <jats:p> <jats:bold>Background:</jats:bold> Collateral circulation (CC) has been associated with recanalization, infarct volume, risk of haemorrhagic transformation and clinical outcome in patients undergoing acute reperfusion therapies. However, its relationship with the development to malignant MCA infarction (mMCAi) has not been evaluated. Our aim was determine the impact of collateral circulation using multiphase CTA (mCTA) on acute phase in the prediction of mMCAi. </jats:p> <jats:p> <jats:bold>Methods:</jats:bold> Consecutive acute stroke &lt;4.5h patients that were evaluated for reperfusion therapies and with a M1-MCA or TICA occlusion by CTA were included. CC was evaluated on mCTA, CC evaluation was performed according to the University Calgary CC Scale; CC was also classified as poor (grades 0-3) or good (grades 4-5). The mMCAi was defined according to previously published clinical and radiological criteria. Recanalization was assessed with TCD at 24-hours and TICI score≥2a in endovascular treatment (ET) patients. Good outcome was defined as mRS 0-2 at 3months. </jats:p> <jats:p> <jats:bold>Results:</jats:bold> 82 patients were included. Mean age: 65.1 ±13.83 years, median baseline NIHSS 18(IQR 5.7), 67.9% M1 and 32.1% TICA occlusions, 53 patients received ET and 57 iv tPA, 15 patients develop a mMCAi. In the univariate analysis, patients with mMCAi had lower CC scores (2.29 Vs. 3.71 p=0.001), higher baseline NIHSS (19.86 Vs. 15.70 p=0.016), lower TIMI reperfusion scores (0 Vs. 2.79 p=00.5) and presence of TICA occlusion was more often compared with M1 occlusion (71% Vs. 11.9%, p=0.033) ET was associated with lower rate of mMCAi development as compared with only i.v. reperfusion treatment (9.4%Vs.29.6%, p=0.028). Furthermore, all patients with poor CC who did not recanalize developed mMCAi (6 Vs. 0, p=0.68) On the multivariate analysis adjusted to age, vessel occlusion, baseline NIHSS and recanalization, the presence of poor CC by mCTA was the only independent predictor of mMCAi (p=0.048 OR: 9.72, 95%IC: 1.387-92.53) </jats:p> <jats:p> <jats:bold>Conclusion:</jats:bold> CC assessment by mCTA independently predicts malignant MCA progression. In patients with persistent occlusion after reperfusion therapies, the presence of poor CC may help in the early malignant MCA detection and management. </jats:p>
