Objective:To explore the association between blood pressure (BP) levels after endovascular thrombectomy (EVT) and the clinical outcomes of acute ischemic stroke (AIS) patients with large vessel occlusion (LVO).Methods:A study was eligible if it enrolled AIS patients older than 18 years, with an LVO treated with either successful or unsuccessful EVT, and provided either individual or mean 24-hour systolic BP values after the end of the EVT procedure. Individual patient data from all studies were analyzed using a generalized linear mixed-effects model.Results:A total of 5874 patients (mean age: 69±14 years, 50% women, median NIHSS on admission: 16) from 7 published studies were included. Increasing mean systolic BP levels per 10 mm Hg during the first 24 hours after the end of the EVT were associated with a lower odds of functional improvement (unadjusted common OR=0.82, 95%CI:0.80-0.85; adjusted common OR=0.88, 95%CI:0.84-0.93) and modified Ranking Scale score≤2 (unadjusted OR=0.82, 95%CI:0.79-0.85; adjusted OR=0.87, 95%CI:0.82-0.93), and a higher odds of all-cause mortality (unadjusted OR=1.18, 95%CI:1.13-1.24; adjusted OR=1.15, 95%CI:1.06-1.23) at 3 months. Higher 24-hour mean systolic BP levels were also associated with an increased likelihood of early neurological deterioration (unadjusted OR=1.14, 95%CI:1.07-1.21; adjusted OR=1.14, 95%CI:1.03-1.24) and a higher odds of symptomatic intracranial hemorrhage (unadjusted OR=1.20, 95%CI:1.09-1.29; adjusted OR=1.20, 95%CI:1.03-1.38) after EVT.Conclusion:Increased mean systolic BP levels in the first 24 hours after EVT are independently associated with a higher odds of symptomatic intracranial hemorrhage, early neurological deterioration, three-month mortality, and worse three-month functional outcomes.

Introduction: Hemorrhagic transformation (HT) after acute ischemic stroke (AIS) may contribute to neurologic deterioration. The current radiologic classification of HT is qualitative and distinguishes petechial hemorrhagic infarction from parenchymal hematoma (PH-1 and PH-2). However, this grading scheme is subjective and may not accurately reflect the impact of HT on neurological status and outcome. We sought to evaluate whether the volume of hemorrhage was a better marker of deterioration. Methods: We evaluated AIS patients with follow-up CT imaging from a prospective stroke genetics study. HT seen within 36 hours of AI was classified using ECASS criteria. In addition, we outlined all confluent areas of hemorrhage to derive hemorrhage volume (HV). We calculated ΔNIHSS as the difference between baseline and 24-hour NIHSS. Early neurological deterioration (END) was defined as ΔNIHSS of -4 points or more. Association of radiologic HT grade and HV with ΔNIHSS and END were analyzed using linear regression and receiver-operating-curve testing. Results: We analyzed 948 stroke patients with median NIHSS 7 (IQR 4-14), 64% receiving tPA and ΔNIHSS +2 (IQR 0-5). 294 (31%) had HT (146 HI1, 63 HI2, 42 PH1 and 43 PH2). HT was associated with higher baseline NIHSS but not with tPA treatment or ΔNIHSS. END occurred in 113 (12%) including 46 with HT (16%) vs. 67 (10%) without HT (p=0.02). Amongst those with HT, the radiologic grade was not associated with ΔNIHSS or END (20% of PH2, 20% of PH1 vs. 15% of HI1/HI2, p=0.40). However, greater HV was associated with ΔNIHSS (adjusting for baseline NIHSS and tPA, estimate -1.5 point per 10-ml, p=0.0001) and with END (those with END had median HV 7 vs. 3-ml, p=0.001). A cut-off of 12-ml had 45% sensitivity and 90% specificity for END (AUC of 0.72). Conclusion: We demonstrated that while HT was associated with a higher risk of END, the ECASS classification alone did not distinguish those who worsened. It appears that hemorrhage volume may better predict worsening NIHSS and END with moderate sensitivity.

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.
