Introduction: Whether thrombectomy added on intravenous thrombolysis (IVT), as compared to IVT alone, is beneficial in minor strokes with large vessel occlusion (LVO) is unknown. To identify predictors of early neurological deterioration (END) following IVT alone may help to select the best candidates for additional thrombectomy. Methods: MINOR-STROKE was a multicentric retrospective registry collecting data of IVT-treated minor strokes (NIHSS≤5) with LVO (internal carotid artery [ICA], M1, M2 or basilar artery; with central reading) treated with or without additional thrombectomy in 45 French stroke units. The patients initially intended for IVT alone, including those who eventually received thrombectomy due to END, were included in the present analysis. END was defined as a ≥4 points on NIHSS within 24hrs following admission. Thrombus length was measured centrally either on T2*-MRI, CT (hyperdense middle cerebral artery) or CT-angiography. Results: Overall, 799 patients were included: mean age 69 years, median NIHSS 3, occlusion located in ICA±M1/M2, proximal M1, distal M1, M2, or basilar artery in 20%, 7%, 19%, 50% and 4% of patients, respectively. Thrombus was visible in 78% of patients (median length 9mm, IQR 6-12mm). END occurred in 15% of patients and was associated with poor 3-month functional outcome (mRS>2: 55% vs. 12% of patients with and without END, respectively). Only 15% of ENDs were due to intracranial haemorrhage. In multivariable analysis, a more proximal occlusion site (M2 [reference], distal M1: OR 2.1 [IC95% 1.1-4.1], proximal M1: OR 3.8 [1.6-9.1], ICA±M1/M2: OR 5.0 [2.6-9.6], basilar artery: OR 4.9 [1.1-4.1]; P <0.001) and a longer thrombus (<6mm [reference], [6-9mm[: OR 1.3 [IC95% 0.6-2.9], [9-12mm[: OR 1.8 [0.8-3.9] and ≥12mm: OR 2.7 [1.3-5.6]; P =0.036) were independently associated with END. END occurred in 33%, 19%, 14%, 7% and 27% of patients with ICA±M1/M2, M1 proximal, M1 distal, M2 and basilar artery, respectively, and in 8%, 10%, 14% et 23% of patients with thrombus length of <6, [6-9[, [9-12[ and ≥12mm, respectively. Conclusion: Our study suggests that thrombus location and length are strong predictors of END in minor strokes with LVO. This may help to select the best candidates for additional endovascular therapy.

Early Neurological Deterioration

Background Early neurological deterioration occurs in approximately 10% acute ischemic stroke patients after thrombolysis. Over half of the early neurological deterioration occurred without known causes and is called unexplained early neurological deterioration. Aims We aimed to explore the development of early neurological deterioration at 24 h after thrombolysis, and whether it could be predicted by the presence of baseline hypoperfusion in lenticulostriate arteries territory in acute ischemic stroke patients. Methods We retrospectively reviewed our prospectively collected database of acute ischemic stroke patients in the unilateral middle cerebral artery territory who had baseline perfusion image and received thrombolysis. Unexplained early neurological deterioration was defined as ≥ 2 points increase of National Institutes of Health Stroke Scale (NIHSS) from baseline to 24 h, without known causes. Hypoperfusion lesions in different territories were identified on perfusion maps. Results A total of 306 patients were included in analysis. Patients with pure lenticulostriate arteries hypoperfusion (defined as the presence of hypoperfusion in lenticulostriate artery territory, but not in middle cerebral artery terminal branch territory) were more likely to have unexplained early neurological deterioration than others (27.6% vs. 6.1%; OR, 5.974; p = 0.001), after adjusting for age, baseline NIHSS and onset to treatment time. Conclusions Patients presenting hypoperfusion in pure lenticulostriate arteries territory were easier to experience unexplained early neurological deterioration.

Background and Purpose: Platelet-to-neutrophil ratio (PNR) was suggested to be an independent protective predictor for 90-days outcomes in acute ischemic stroke (AIS) patients in previous studies. This study aims to investigate the association between PNR and outcomes of AIS in intravenous thrombolysis (IVT) group. Methods: Data on acute ischemic stroke patients who received intravenous thrombolysis from April 2015 to March 2019 were collected. We defined the PNR value at admission as pre-IVT PNR and after IVT within 24 h was defined as post-IVT PNR. Clinical outcome indicators included early neurological deterioration (END), hemorrhagic transformation (HT), delayed neurological deterioration (DND), and poor 3-month outcome (3m-mRS >2). Results: A total of 581 patients were enrolled in the final analysis. The age was 61(53-69) years, and 423(72.8%) were males. Post-IVT PNR was independently associated with hemorrhagic transformation (OR = 0.974; 95%CI = 0.956-0.992; P=0.006), early neurological deterioration (OR = 0.939; 95%CI = 0.913-0.966; P = 0.01), delayed neurological deterioration (OR = 0.949; 95%CI = 0.912- 0.988; P = 0.011), and poor outcome (OR = 0.962; 95%CI = 0.948-0.976; P<0.001). PNR level was identified as high (at the cut-off value or above) or low (below the cut-off value) according to receiver operating curve (ROC) analyses on each endpoint. Comparison of early neurological deterioration, hemorrhagic transformation, delayed neurological deterioration, and poor 3-month outcome (3m-mRS >2) between patients at high and low levels for platelet-to-neutrophil ratio (PNR) showed statistical differences (p<0.001). Conclusions: Post-IVT PNR was independently associated with early neurological deterioration, hemorrhagic transformation, delayed neurological deterioration, and poor 3-month outcome. Lower PNR can predict a worse outcome.

This work was aimed to study the risk factors and prognostic treatment for acute ischemic stroke (AIS) patients with early neurological deterioration (END) after intravenous thrombolytic therapy via compressed sensing algorithm-based magnetic resonance imaging (CS-MRI). 231 patients who were diagnosed with AIS were selected, and the final involved number of patients was 182. Patients with AIS were treated with intravenous thrombolysis with alteplase within 4.5 hours of onset. After treatment, patients with early neurological deterioration were defined as the deteriorating group and those without early neurological impairment were defined as the nondeteriorating group. In univariate analysis, hypertension, white blood cell count, and National Institutes of Health Stroke Scale (NIHSS) score were correlated with the occurrence of END. Under the CS-MRI theory, the two groups of patients were evaluated for middle cerebral artery basal ganglia infarction and internal watershed infarction. After univariate analysis, the P < 0.1 variables were taken as the independent variable, and the binary logistic regression model was adopted for multivariate regression analysis. It was disclosed that NIHSS score was not correlated with the occurrence of early neurological function deterioration, while homocysteine was. Hypertension, white blood cell count, homocysteine, and NIHSS score were risk factors for END. The image analysis revealed that the incidence of deteriorating basal ganglia infarction group was lower relative to the nondeteriorating group, and the incidence of watershed infarction was higher in the deteriorating group versus the nondeteriorating group. The image analysis suggested that predicting the occurrence of END through risk factors can actively provide endovascular treatment for patients with AIS.

Abstract Background Some patients with acute middle cerebral artery stroke (MCA-stroke) cannot benefit from thrombolysis and develop early neurological deterioration (END) within 24 hours. Except for several defenitive causes such as symptomatic intracerebral hemorrhage, malignant edema, and early recurrent stroke, no definitive mechanism (unexplained END) account for majority of END cases deserving our attention. Methods We retrospectively collected 142 MCA-stroke patients who had pretreatment multimodal CT including non-contrast CT (NCCT), CT angiography (CTA) and CT perfusion (CTP) and received intravenous thrombolytic therapy within 4.5h of onset and. Unexplained END was denited as NIHSS scores increased from baseline within 24 hours after thrombolysis ≥ 4 points or death without definite causes. The clinical and imaging data based on multimodal CT were compared between unexplained END and no END through univariate and multivariate regression analyses. Results The prevalence of unexplained END (24 patients, 16.9%) outnumbered the prevalence of END due to other causes. Univariate analysis showed that higher admission glucose (P= 0.039), lower initial NIHSS score (P=0.026), lower r-LMC score (P= 0.003), proximal occlusion (P=0.003) and large penumbra volume(P<0.001) were more frequently observed in patients with unexplained END; In multivariate analysis, lower NIHSS score (OR=1.19; 95% CI, 1.07-1.32; P=0.001), proximal occlusion (OR=0.32; 95% CI, 0.06-0.92; P=0.038), lower r-LMC score (OR=1.17; 95% CI, 1.02-1.35; P=0.028) and larger penumbra volume (OR=0.98; 95% CI, 0.96-0.99; P=0.003) were associated with unexplained END. Conclusion Lower NIHSS score, proximal occlusion, lower r-LMC score and larger penumbra volume can predict unexplained END in the hyperacute phase of MCA-stroke and contribute to develop treatment strategies.
