Thrombolysis in Ischemic Stroke Without Arterial Occlusion at Presentation Clinical Sciences
Conclusions— This study provides crucial data that patients with ischemic stroke who do not have visible arterial occlusion at presentation may benefit from thrombolysis.

Smoking-Thrombolysis Paradox: Recanalization and Reperfusion Rates After Intravenous Tissue Plasminogen Activator in Smokers With Ischemic Stroke Original Contributions
Conclusions— Smoking is independently associated with recanalization and reperfusion, indicating that thrombolytic therapy acts more effectively in smokers; because of small numbers, these results should be considered preliminary. Clinical Trial Registration— URL: http://clinicaltrials.gov. Unique Identifier: NCT00715533.

Identification of Reversible Disruption of the Human Blood-Brain Barrier Following Acute Ischemia Brief Reports
Conclusions— This study demonstrates that diffuse, mild BBB disruption in the acutely ischemic human brain is reversible with reperfusion. This study also confirms prior findings that focal severe BBB disruption confers an increased risk of hemorrhagic transformation in patients treated with intravenous tissue-type plasminogen activator.

Thrombolytic Therapy Is an Only Determinant Factor for Stroke Evolution in Large Anterior Choroidal Artery Infarcts
Conclusions: Thrombolytic therapy is an only determinant factor for stroke evolution in large AChA infarcts, which reduced the risk of stroke evolution and improved functional outcome.

Ischemic Stroke in Evolution: Predictive Value of Perfusion Computed Tomography
Background: Various perfusion computed tomography (PCT) parameters have been used to identify tissue at risk of infarction in the setting of acute stroke. The purpose of this study was to examine predictive value of the PCT parameters commonly used in clinical practice to define ischemic penumbra. The patient selection criterion aimed to exclude the effect of thrombolysis from the imaging data.Methods: Consecutive acute stroke patients were screened and a total of 18 patients who initially underwent PCT and CT angiogram (CTA) on presentation but did not qualify to receive thrombolytic therapy were selected. The PCT images ...

Translational perspectives on perfusion–diffusion mismatch in ischemic stroke
Magnetic resonance imaging has tremendous potential to illuminate ischemic stroke pathophysiology and guide rational treatment decisions. Clinical applications to date have been largely limited to trials. However, recent analyses of the major clinical studies have led to refinements in selection criteria and improved understanding of the potential implications for the risk vs. benefit of thrombolytic therapy. In parallel, preclinical studies have provided complementary information on the evolution of stroke that is difficult to obtain in humans due to the requirement for continuous or repeated imaging and pathological veri...

Fatal Intracranial Hemorrhage after Intravenous Thrombolytic Therapy for Acute Ischemic Stroke Associated with Cancer-related Nonbacterial Thrombotic Endocarditis
Nonbacterial thrombotic endocarditis (NBTE) is associated with hypercoagulability in patients with inflammatory states such as cancer and autoimmune diseases. Cardiac vegetations caused by NBTE often lead to life-threatening systemic thromboembolism that most frequently affects the brain, spleen, and kidneys. A 54-year-old woman diagnosed with ovarian cancer suddenly developed back pain and left hemiparesis. Although intravenous alteplase (rt-PA) therapy was administered to treat hyperacute ischemic infarction detected by magnetic resonance imaging, intracranial hemorrhage occurred in the left hemisphere several hours late...

Intravenous Thrombolysis in Posterior Circulation Stroke
Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.

Frequency of Hemorrhage on Follow Up Imaging in Stroke Patients Treated With rt-PA Depending on Clinical Course
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score. Introduction Brain imaging 24–36 h after systemic thrombolysis for acute ischemic stroke is recommended in American Stroke Association and European Stroke Organization guidelines (1, 2). Brain imaging is performed to detect secondary bleeding or hemorrhagic transformation in order to adapt medical stroke prevention if necessary. Guideline recommendations are based on the results of the first study on rt-PA...

Management of Acute Ischemic Stroke-Specific Focus on Anesthetic Management for Mechanical Thrombectomy.
Abstract Acute ischemic stroke is a neurological emergency with a high likelihood of morbidity, mortality, and long-term disability. Modern stroke care involves multidisciplinary management by neurologists, radiologists, neurosurgeons, and anesthesiologists. Current American Heart Association/American Stroke Association (AHA/ASA) guidelines recommend thrombolytic therapy with intravenous (IV) alteplase within the first 3-4.5 hours of initial stroke symptoms and endovascular mechanical thrombectomy within the first 16-24 hours depending on specific inclusion criteria. The anesthesia and critical care provider may b...

Pre- and in-hospital delays in the use of thrombolytic therapy for patients with acute ischemic stroke in rural and urban Egypt
ConclusionThe limited availability of stroke-ready hospitals in rural Egypt leads to delays in stroke management, with subsequent treatment inequality of rural patients with acute stroke.

Thrombolytic Therapy in Wake-Up Stroke Patients
Conclusions: Available data suggest promising strategies to identify WUS patients who may benefit from thrombolysis. Once on-going trials are complete, there may be sufficient information to redefine tPA eligibility for previously excluded patients.

Acute Ischemic Stroke.
Authors: Rossi UG, Ierardi AM, Cariati M Abstract A 77-year-old woman with a history of hypertension developed acute onset of aphasia and right hemiplegia and hemisensory loss. She was urgently referred to emergency department. Cerebral multidetector computed tomographic angiography (MD-CTA) revealed an acute ischemic stroke due to the occlusion of the left middle cerebral artery (Figure 1). Since the symptoms started three hours previously, the patient was candidate for mechanical thrombectomy. The patient then performed a selective digital subtraction angiography (DSA) of the left internal carotid artery that con...
