Outcomes after Tissue Plasminogen Activator Administration under the Drip and Ship Paradigm May Differ According to the Regional Stroke Care System
The drip and ship paradigm for stroke patients enhances the rate of using intravenous tissue plasminogen activator (IVT) in community hospitals. The safety and outcomes of patients treated with IVT for acute ischemic stroke (AIS) under the drip and ship paradigm were compared with patients directly treated at a comprehensive stroke center in the Busan metropolitan area of Korea. This was a retrospective study of patients with AIS treated with IVT between January 2009 and January 2012. Information on patients' baseline characteristics, neuroimaging, symptomatic intracerebral hemorrhage (sICH), and outcome 90 days after usi...

Safety and Effectiveness of Endovascular Treatment after 6 Hours of Symptom Onset in Patients with Anterior Circulation Ischemic Stroke: A Matched Case Control Study
Conclusions: We did not observe any evidence of benefit in halting neurologic worsening or improving outcomes among patients undergoing endovascular treatment for treatment of an anterior circulation ischemic stroke after 6 hours of symptom onset. Strong evidence of both the safety and efficacy of emergent endovascular treatment when administered to patients with stroke in the anterior circulation is needed.

Early Magnetic Resonance Imaging Decreases Hospital Length of Stay in Patients with Ischemic Stroke
Imaging modalities are important part of stroke evaluation. Noncontrast head computed tomography (CT) is the initial imaging modality in acute stroke and although important to rule out acute hemorrhage and making a decision on thrombolytic treatment, ischemic changes may not be visible on CT for up to 24 hours. Magnetic resonance imaging (MRI) brain is an invaluable tool to confirm an ischemic stroke and facilitates stroke evaluation. Objective of this study was to investigate the correlation between time to MRI and length of hospital stay.

Diversity of Stroke Presentation in CADASIL: Study from Patients Harboring the Predominant NOTCH3 Mutation R544C
This study investigated the clinical stroke presentation and cranial magnetic resonance imaging (MRI) findings in a group of patients with CADASIL. We reviewed the clinical stroke presentation and brain MRI findings in 73 consecutive Korean patients aged>18 years diagnosed with CADASIL between May 2004 and April 2009. Brain MRI images were also scored for lacunar infarction and cerebral microbleeds. Intracranial atherosclerosis (ICAS) was assessed by magnetic resonance angiography. Disability was measured with the modified Rankin scale (mRS) and classified as good (mRS score 0-2) or poor (mRS score 3-5). In this study, 65 ...

Cerebral Microbleeds and Chronic Kidney Disease in Acute Ischemic Stroke Patients with Atrial Fibrillation
Background: Cerebral microbleeds (CMBs) are associated with the risk of intracerebral hemorrhage in stroke patients with atrial fibrillation (AF). We investigated the association between CMBs and chronic kidney disease (CKD) in patients with acute ischemic stroke and AF. Methods: We retrospectively examined consecutive patients with acute ischemic stroke and AF who underwent brain gradient-echo T2*-weighted magnetic resonance imaging. The number and distribution (lobar, deep or infratentorial, and mixed) of CMBs were assessed.

Nascent Deep Microbleeds and Stroke Recurrences
This study investigated the contributions of nascent deep MBs to stroke recurrence.Methods: We prospectively analyzed nascent deep MBs in patients admitted to our hospital who were treated for index strokes between April 2004 and November 2009. The number of nascent deep MBs was counted on T2∗-weighted MRI scans around 1 year after the index strokes, and compared to previous MRIs on admission. Stroke recurrence–free rate curves were generated using the Kaplan–Meier method using the log-rank test. The odds ratio for nascent deep MBs was derived using a multivariate logistic regression model that was based on recurren...

Intravenous Tissue Plasminogen Activator Therapy for an Acute Ischemic Stroke Patient with Later Diagnosed Unilateral Moyamoya Syndrome
We report the use of intravenous tissue plasminogen activator (t-PA) therapy in a 38-year-old patient who was later diagnosed with unilateral moyamoya syndrome. The patient had a sudden onset of unconsciousness, vomiting, dysarthria, and tetraparesis. A neurologic examination revealed consciousness disturbance, right central facial nerve palsy, dysarthria, and tetraparesis with bilateral exotropia and horizontal gaze palsy. A magnetic resonance imaging scan on admission did not reveal fresh cerebral infarction or hemorrhage, but magnetic resonance angiography revealed severe stenosis at the terminal portion of left interna...

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...

Intraventricular Silicone Oil Migration Resembling Hemorrhagic Complication in a Patient with Ischemic Stroke Receiving Antithrombotic Therapy
We report herein a case of intraventricular silicone oil migration, a rare complication of intraocular silicone oil tamponade, mimicking a hemorrhage during antithrombotic therapy for ischemic stroke. A 62-year-old male patient with a history of diabetic retinopathy was admitted for right hemiparesis and dysarthria. Brain magnetic resonance imaging on admission showed an acute left-sided ventral medullary infarction, and antithrombotic therapy was started. Head computed tomography done on the next day after admission showed an area of high-density resembling a hematoma in the lateral ventricle.
