Posttreatment National Institutes of Health Stroke Scale Is Superior to the Initial Score or Thrombolysis in Cerebral Ischemia for 3-Month Outcome Clinical Sciences
Background and Purpose—The majority of ischemic stroke patients receiving endovascular recanalization therapy (EVT) experience variable changes of neurological severities during the hyperacute period. We hypothesized that the National Institutes of Health Stroke Scale (NIHSS) score after EVT is a better prognostic factor compared with the initial NIHSS score or revascularization status.Methods—We identified 566 stroke patients who received EVT at Seoul National University Bundang Hospital between April 2008 and December 2015. We prospectively collected post-EVT NIHSS score, which was measured in the angiography suite b...

Internal Cerebral Vein Asymmetry on Follow-up Brain Computed Tomography after Intravenous Thrombolysis in Acute Anterior Circulation Ischemic Stroke Is Associated with Poor Outcome
Background: Identifying early predictors of functional outcome after acute ischemic stroke (AIS) is important for planning rehabilitation strategies. Internal cerebral veins (ICV) drain deep parts of brain, run parallel to each other, and consistently seen on computed tomography angiography (CTA). Even minor asymmetry in their filling can be identified. We hypothesized that venous drainage would be impaired in patients with acute occlusion of internal carotid artery or middle cerebral artery. Because systemic thrombolysis can alter the vascular findings, we evaluated the relationship between ICV asymmetry on follow-up CTA ...

Histology of Thrombectomy Specimen Reveals Cardiac Tumor Embolus in Cryptogenic Young Stroke
A 25-year-old woman presented with acute onset of right hemiplegia and global aphasia with National Institutes of Health Stroke Scale score of 19. Computed tomography angiography demonstrated occlusion of the left proximal middle cerebral artery. She was thrombolysed with intravenous recombinant tissue plasminogen activator (0.6  mg/kg) within 3 hours of onset of symptoms and was taken up for mechanical thrombectomy. The retrieved specimen appeared pale white and soft; histopathologic examination revealed a papillary neoplasm composed of papillae with hyalinized cores lined by endothelium, consistent with papillary fibro...

Clinical significance of CT angiographic assessment of collateral circulation combined with serum NLRP1 levels in ischemic stroke patients
This study showed that the serum NLRP1 levels were remarkably decreased in ischemic stroke patients. In addition, the serum NLRP1 levels and ASITN/SIR grade could predict the prognosis of ischemic stroke patients.PMID:37000063 | DOI:10.1097/MD.0000000000033433

Drip-and-Ship for Thrombectomy Treatment in Patients With Acute Ischemic Stroke Leads to Inferior Clinical Outcomes in a Stroke Network Covering Vast Rural Areas Compared to Direct Admission to a Comprehensive Stroke Center
Discussion: Our data suggest that patients who had an acute ischemic stroke admitted directly to a CSC may have better 90-day outcomes than those transferred secondarily for thrombectomy from a PSC.

Alteplase versus tenecteplase for thrombolysis after ischaemic stroke (ATTEST): a phase 2, randomised, open-label, blinded endpoint study
This study is registered with ClinicalTrials.gov, number NCT01472926. Findings Between Jan 1, 2012, and Sept 7, 2013, 355 patients were screened, of whom 157 were eligible for intravenous thrombolysis, and 104 patients were enrolled. 52 were assigned to the alteplase group and 52 to tenecteplase. Of 71 patients (35 assigned tenecteplase and 36 assigned alteplase) contributing to the primary endpoint, no significant differences were noted for percentage of penumbral salvaged (68% [SD 28] for the tenecteplase group vs 68% [23] for the alteplase group; mean difference 1·3% [95% CI −9·6 to 12·1]; p=0·81). Neither incide...

The Number of Stenotic Intracranial Arteries Is Independently Associated with Ischemic Stroke Severity
by Xiaodan Wei, Zhuang Liu, Min Li, Chunhua Yang, Wenming Wang, Xianglin Li, Shuping Zhang, Xuri Li, Geng Tian, Jonas Bergquist, Bin Wang, Jia Mi BackgroundThe severity of ischemic stroke symptoms varies among patients and is a critical determinant of patient outcome. To date, the association between the number of stenotic intracranial arteries and stroke severity remains unclear. AimsWe aimed to investigate the association between the number of stenotic major intracranial arteries (NSMIA) and ischemic stroke severity, as well as the degree of stenosis and common stroke risk factors. MethodsWe performed a retrospective ana...

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...

Clinical Evaluation of Lacunar Infarction and Branch Atheromatous Disease
Patients with branch atheromatous disease (BAD) are more likely to experience neurologic deficits compared with those with lacunar infarction (LI), although both disorders are forms of intracranial deep brain infarction. We clinically evaluated patients with BAD (n = 42) and LI (n = 57) to investigate why patients with BAD tend to experience progressing stroke. Patients presenting to our hospital with acute ischemic stroke between April 2008 and March 2009 were screened. LI was defined as an intracerebral lesion 2-point increase in the National Institutes of Health Stroke Scale within 48 hours of stroke onset. Progressing ...

Dabigatran etexilate: management in acute ischemic stroke.
Abstract A 54-year-old man treated with dabigatran experienced new onset of a stroke with a score of 9 on the National Institutes of Health Stroke Scale. Administration of recombinant tissue plasminogen activator (rtPA) was not recommended because of the dabigatran therapy. Angiography showed occlusion of the left middle cerebral artery by an embolic thrombus. Suction thrombectomy achieved flow through the inferior division of the artery. Computed tomography of the head showed possible intracranial hemorrhage, and dabigatran reversal was attempted with prothrombin complex concentrate and recombinant factor VIIa. C...

Current trends in the management of acute ischemic stroke
Srinivasan ParamasivamNeurology India 2015 63(5):665-672Stroke is the leading cause of disability and most of the cases are those of ischemic stroke. Management strategies especially for large vessel occlusive stroke have undergone a significant change in the recent years that include widespread use of thrombolytic medications followed by endovascular clot removal. For successful treatment by endovascular thrombectomy, the important factors are patient selection based on clinical criterion including age, time of onset, premorbid clinical condition, co-morbidities, National Institute of Health Stroke Scale, and imaging crit...
