Differences in characteristics and outcomes after endovascular therapy: A single-center analysis of patients with vertebrobasilar occlusion due to underlying intracranial atherosclerosis disease and embolism.

This study aimed to compare characteristics and outcomes of VBAO due to intracranial atherosclerotic disease (ICAD) and embolisms and identify baseline predictors of ICAD. METHODS: Patients with VBAO who received endovascular therapy (EVT) were retrospectively analyzed. Participants fulfilling the criteria were classified as the ICAD group (focal stenosis of>70%, or fixed stenosis>50% in addition to either flow and perfusion impairment on angiography or an evident reocclusion tendency) and the embolism group (defined as no evidence of focal significant stenosis after thrombolysis or thrombectomy). Baseline characteristics and outcomes after EVT were compared between the two groups, and logistic regression was performed to explore the factors associated with ICAD. RESULTS: Among the 133 patients enrolled, 95 (71.4%) patients were categorized in the ICAD group, and 38 (28.6%) in the embolism group. A history of atrial fibrillation (odds ratio (OR) 0.142; 95% confidence interval (CI) (0.028-0.707), p = 0.017), distal basilar artery occlusion (OR 0.107; 95% CI (0.040-0.289), p

Authors: Shahedah KK, Khoo CS, Wan Nur Nafisah WY, Ng CF, Noor Ashikin I, Mohd Naim MY, Syazarina Sharis O, Rozman Z, Wan Asyraf WZ Abstract A 42-year-old female admitted with new-onset atrial fibrillation had a wake-up stroke on the high-dependency unit and the time last seen well (TLSW) was 6.5 h. She suffered left-sided body weakness and her National Institutes of Health Stroke Scale (NIHSS) score was 17. An emergency CT perfusion showed right M1 segment occlusion with more than 50% penumbra. She was given recombinant tissue plasminogen activator (r-tPA) at 9 h from TLSW. An immediate diagnostic angiog...

Conclusions: There are only minor differences between clinical and imaging characteristics of WUS patients and patients who arrive in the hospital within the time criteria for intravenous or endovascular treatment. Therefore, CT imaging may help to identify WUS patients who would benefit from treatment and rule out those patients with severe ischemia and poor collaterals.Cerebrovasc Dis 2018;45:236 –244

Introduction The smoking-thrombolysis paradox has been well described in myocardial infarction. However, its existence in the stroke population remains elusive. In the past decade, several studies have investigated the phenomenon with mixed results. We sought to determine whether clinical outcomes differ between smokers and non-smokers with acute ischemic stroke undergoing endovascular therapy. Methods We reviewed our prospectively collected endovascular database at a tertiary care academic institution. All patients who underwent endovascular therapy for large vessel occlusion acute ischemic stroke were categorized into c...

Background and purposeChronic hypoperfusion from athero‐stenotic lesions is thought to lead to better collateral recruitment compared to cardioembolic strokes. It was sought to compare collateral flow in stroke patients with atrial fibrillation (AF) versus stroke patients with cervical atherosclerotic steno‐occlusive disease (CASOD). MethodThis was a retrospective review of a prospectively collected endovascular database. Patients with (i) anterior circulation large vessel occlusion stroke, (ii) pre‐treatment computed tomography angiography (CTA) and (iii) intracranial embolism from AF or CASOD were included. CTA col...

A middle-aged woman with known severe coronary disease had onset of substernal chest pain while at dialysis. 911 was called. A prehospital ECG was similar to the first ED ECG, which is shown below. The patient arrived with a systolic blood pressure of 90 mm Hg, too low to administer nitroglycerine. An initial lactate was elevated at 5.5.She was given aspirin, heparin, and ticagrelor.Here is her initial ED 12-lead ECG:There is atrial fibrillation with a rate of approximately 114.There is extreme ST depression in multiple leads and ST elevation in aVR, suggesting left main and/or 3 vessel disease ischemia...

Background We hypothesized that the relative cerebral blood volume (rCBV) ratio on perfusion-weighted imaging (PWI) using MRI might serve as a predictor of early recanalization (ER) after intravenous tissue plasminogen activator (IV t-PA) administration for acute ischemic stroke. Methods Patients with acute middle cerebral artery (MCA) ischemic stroke (IS) were enrolled in the study. They were evaluated by MRI, including PWI and diffusion-weighted imaging, before administration of IV t-PA and underwent digital subtraction angiography (DSA) of the brain within 2 h after t-PA administration. We compared the rCBV ratio ...
