Background— Matrix metalloproteinase (MMP) expression is related to blood brain barrier disruption after cerebral ischemia. Moreover, MMP inhibitors reduce hemorrhagic transformation (HT) embolic ischemia in tissue plasminogen activator (t-PA)–treated animals. We aimed correlate plasmatic levels with the appearance of intracranial bleeding complications stroke patients treated t-PA. Methods and Results— Serial MMP-2 MMP-9 determinations were performed (ELISA, ng/mL) 41 strokes involving...
Background and Purpose— We sought to evaluate the effects of administration microbubbles (MBs) on beginning, speed, degree middle cerebral artery (MCA) recanalization during systemic thrombolysis continuous 2-MHz pulsed-wave transcranial Doppler (TCD) monitoring. Methods— evaluated 111 patients with acute stroke attributable MCA occlusion treated intravenous tissue plasminogen activator (tPA). Thirty-eight were tPA plus 2-hour TCD monitoring 3 doses 2.5 g (400 mg/mL) galactose-based MBs...
The effects and risks of endovascular thrombectomy 6 to 24 hours after stroke onset due basilar-artery occlusion have not been extensively studied.
Abnormal expression of some matrix metalloproteinases (MMP) has shown to play a deleterious role in brain injury experimental models cerebral ischemia. We aimed investigate MMP-2 (gelatinase A) and MMP-9 B) parenchyma both ischemic hemorrhagic strokes.Postmortem fresh tissue from 6 8 stroke patients was obtained within the first hours after death. Finally, 78 samples different areas (infarct, peri-infarct, perihematoma contralateral hemisphere) were studied. To quantify gelatinase content we...
Background and Purpose— Although tandem internal carotid artery/middle cerebral artery (MCA; TIM) occlusion has been associated with low recanalization rate after IV tissue plasminogen activator (tPA), its independent contribution on stroke outcome remains unknown. Moreover, whether the relative resistance to thrombolysis in lesions varies depending location of MCA clot uncertain. Methods— Two hundred twenty-one consecutive patients an acute treated tPA were studied. Emergent ultrasound...
Background and Purpose— Because there is no biologic marker offering precise information about stroke etiology, many patients receive a diagnosis of undetermined even after all available diagnostic tests are done, precluding correct treatment. Methods— To examine the value panel biochemical markers to differentiate etiologies, consecutive acute were prospectively evaluated. Brain computed tomography, ultrasonography, cardiac evaluations, other done identify an etiologic according TOAST...
<h3>Importance</h3> It is estimated that only 27% of patients with acute ischemic stroke and large vessel occlusion who undergo successful reperfusion after mechanical thrombectomy are disability free at 90 days. An incomplete microcirculatory might contribute to these suboptimal clinical benefits. <h3>Objective</h3> To investigate whether treatment adjunct intra-arterial alteplase improves outcomes following reperfusion. <h3>Design, Setting, Participants</h3> Phase 2b randomized,...
Advanced imaging for patient selection in mechanical thrombectomy is not widely available.To compare the clinical outcomes of patients selected by noncontrast computed tomography (CT) vs those perfusion (CTP) or magnetic resonance (MRI) extended time window.This multinational cohort study included consecutive with proximal anterior circulation occlusion stroke presenting within 6 to 24 hours last seen well from January 2014 December 2020. This was conducted at 15 sites across 5 countries...
On 11 March 2020, World Health Organization (WHO) declared the COVID-19 infection a pandemic. The risk of ischemic stroke may be higher in patients with similar to those other respiratory tract infections. We present comprehensive set practice implications single document for clinicians caring adult acute confirmed or suspected infection.The were prepared after review data reach consensus among experts from 18 countries. writers used systematic literature reviews, reference previously...
Rationale Efficacy of mechanical thrombectomy for acute stroke due to large vessel occlusion initiated beyond 6 h time last seen well has not been demonstrated in randomized trials.
