Impacts of Cigarette Smoking and Basilar Artery Flow on 1-year Recovery in 3-Month survivors of Intracranial Vertebrobasilar Artery Dissection-related Ischemic Stroke.
CONCLUSIONS: Our results suggest that adequate blood flow may be key to functional recovery after iVBDcaused PCS. Methods to improve blood flow and tissue perfusion after iVBD-caused PCS should be considered in the future clinical studies with the purpose to improve functional recovery in these patients.

Association between Leukoaraiosis and Poor Outcome is not due to Reperfusion Inefficiency after Intravenous Thrombolysis
Abstract Leukoaraiosis (LA) is associated with structural and functional cerebrovascular impairment, which may compromise the capacity of ischemic tissue to maximize reperfusion after intravenous thrombolysis (IVT). We aimed to determine whether severe LA is correlated with reperfusion inefficiency, which contributes to infarct growth and poor functional outcome. We analyzed data from our consecutive acute ischemic stroke (AIS) patients who had acquired baseline and 24-h follow-up diffusion- and perfusion-weighted imaging. Reperfusion was defined as reduction of ≥70 % of hypoperfusion lesion at 24 h from basel...

Computed tomography perfusion-based thrombolysis in wake-up stroke
Abstract Wake-up stroke (WUS) patients are typically excluded from reperfusion treatment, as the time of symptoms onset is unknown. The purpose of this study is to evaluate the clinical outcome and safety of intravenous thrombolysis with rt-PA in patients with WUS eligible for therapy using computed tomography perfusion criteria (CTP), compared to patients treated with rt-PA within 4.5 h of symptoms onset (non-WUS). This is an experimental, open-label trial, controlled against the best therapy currently in use. Primary endpoints were functional independence after 3 months [modified Rankin scale (mRS) ≤ 1] ...

Late Thrombectomy in Clinical Practice
ConclusionIn clinical practice, the high number of patients with a  good clinical outcome after endovascular therapy ≥ 6–24 h as in DAWN/DEFUSE3 could not be achieved. Similar outcomes are seen in patients selected for EVT ≥ 6 h based on factors other than CTP. Patients triaged without CTP showed trends for shorter arrival to reperfusion times and higher rates of independence.
