Background: Although tobacco use, the majority of which is cigarette smoking, increases the risk of incident stroke, there are inconsistent data regarding the effect of tobacco use on neurological outcomes after acute ischemic stroke. Several prior studies have suggested that smoking could be protective after stroke, which has been termed the "smoker’s paradox." Methods: We pooled three data sources to explore the effect of tobacco use on neurologic outcome in acute stroke patients. The first was the Blood Pressure after EVT in Stroke (BEST) study, the second was the NINDS tPA trial, and the third was the Interventional Management of Stroke (IMS) III trial. The primary outcome is 90-day mRS 0-2 (good outcome). We fit logistic regression models to good outcome, both unadjusted and adjusted for patient age, NIHSS, and sICH. Results: Our pooled cohort had 1,671 acute stroke patients, of which 480 (28.7%) used tobacco. In an unadjusted model, tobacco use was associated with good outcome (OR 1.42, 95% CI 1.15-1.76, p=0.001). However, in the adjusted model, this association was no longer significant (aOR 0.98, 95% CI 0.76-1.25, p=0.868). If we stratify by placebo-treated (n=310), tPA-treated (n=513), and EVT-treated (n=836), we continue to find that tobacco use is not associated with good neurologic outcome in adjusted analyses specific to these subgroups. An additional subgroup analysis of the EVT-treated patients that adjusted for successful procedural recanalization (TICI 2b-3) was not significant. Patients who used tobacco were younger (mean age, 60.5 vs. 69.2 years, p<0.001). Adjusting for age alone rendered the association between tobacco use and good outcome insignificant (aOR 1.05, 95% CI 0.84-1.32, p=0.666). Conclusions: This is the first adjusted analysis to examine the association between tobacco use and neurologic outcome in EVT-treated patients. We find that tobacco use is not protective after acute ischemic stroke that is untreated or treated with tPA or EVT. The univariate association of tobacco use with good outcome is accounted for by tobacco users being younger.

Introduction : Rescue treatment for failed thrombectomy in patients with acute ischemic stroke (AIS) from large vessel occlusion (LVO) remains controversial. We report our institutional experience with using intracranial stenting of occlusion refractory to aspiration and stent retriever thrombectomy. Methods : We performed a retrospective review of our prospectively maintained thrombectomy database to identify the LVO AIS patients who underwent intracranial stenting during endovascular thrombectomy at our comprehensive stroke center between January 2015 and July 2021. Modified Rankin scale (mRS) at 90 days was used as primary outcome. A good neurologic outcome was defined as mRS 0–3, and a poor neurologic outcome is defined as mRS score between 4–6. Secondary outcomes included symptomatic intracerebral hemorrhage (sICH) based on ECASS criteria, and in‐hospital mortality. Results : We identified 52 acute ischemic stroke patients who underwent intracranial stenting acutely. Thirty‐three patient (63.4%) are males. Median age was 64 years (Interquartile range (IQR 57–74), median baseline mRS was 0 (IQR 0–1), median NIHSS score was 13 (IQR 7–18), and median ASPECTS was 9 (IQR 8–10). Thirty six percent of the patients had a vertebrobasilar occlusion, 34% had a middle cerebral occlusion (M1 segment), and 14% had an M2 segment occlusion. The median number of thrombectomy passes prior to stenting was 3 (IQR 2–4). In 48% of patients, a combination of aspiration and stent retriever techniques were used prior to intracranial stenting. The Enterprise stent was the most commonly used stent (51.9%), followed by Wingspan stent (25%), and Neuroform Atlas stent (21.5%). Majority of the patients (93%) were loaded with anti‐thrombotics intraoperatively, with rectal Aspirin and intravenous Integrilin being the most commonly used agents. Successful recanalization (TICI 2 B or better) was achieved in 96% of the patients, while the remaining 2 patients were graded as TICI 2A recanalization. Fifty percent of the patients had good outcome at 90 days. A total of 4 patients (8%) developed a sICH, with a 90 day mortality of rate of 15.4% (8/52). Conclusions : Rescue intracranial stenting appears to be a safe and effective approach in patients with emergent large vessel occlusion refractory to thrombectomy. Larger studies are warranted to further establish the safety and efficacy of this approach.

Background. Although research suggests that blood pressure variability (BPV) is detrimental in the weeks to months after acute ischemic stroke, it has not been adequately studied in the acute setting. Methods. We reviewed acute ischemic stroke patients from 2007 to 2014 with anterior circulation stroke. Mean blood pressure and three BPV indices (standard deviation, coefficient of variation, and successive variation) for the intervals 0–24, 0–72, and 0–120 hours after admission were correlated with follow-up modified Rankin Scale (mRS) in ordinal logistic regression models. The correlation between BPV and mRS was further analyzed by terciles of clinically informative stratifications. Results. Two hundred and fifteen patients met inclusion criteria. At all time intervals, increased systolic BPV was associated with higher mRS, but the relationship was not significant for diastolic BPV or mean blood pressure. This association was strongest in patients with proximal stroke parent artery vessel occlusion and lower mean blood pressure. Conclusion. Increased early systolic BPV is associated with worse neurologic outcome after ischemic stroke. This association is strongest in patients with lower mean blood pressure and proximal vessel occlusion, often despite endovascular or thrombolytic therapy. This hypothesis-generating dataset suggests potential benefit for interventions aimed at reducing BPV in this patient population.
