Quantitative Imaging of Cerebral Thromboemboli In Vivo Basic Sciences
Background and Purpose—Quantitative imaging for the noninvasive assessment of thrombolysis is needed to advance basic and clinical thrombosis-related research and tailor tissue-type plasminogen activator (tPA) treatment for stroke patients. We quantified the evolution of cerebral thromboemboli using fibrin-targeted glycol chitosan–coated gold nanoparticles and microcomputed tomography, with/without tPA therapy.Methods—We injected thrombi into the distal internal carotid artery in mice (n=50). Fifty-five minutes later, we injected fibrin-targeted glycol chitosan–coated gold nanoparticles, and 5 minutes after that, w...

Ischemic Stroke After Treatment of Intraprocedural Thrombosis During Stent-Assisted Coiling and Flow Diversion Brief Report
Conclusions—Current protocols for treatment of intraprocedural thrombosis associated with placement of intra-arterial devices were effective in preventing ischemic stroke in ≈80% of cases. Current smoking was the only independent predictor of ischemic stroke.

Rivaroxaban Versus Dabigatran or Warfarin in Real-World Studies of Stroke Prevention in Atrial Fibrillation Clinical Sciences
Conclusions—In this systematic review and meta-analysis, rivaroxaban was as effective as dabigatran, but was more effective than warfarin for the prevention of stroke/thromboembolism in atrial fibrillation patients. Major bleeding risk was significantly higher with rivaroxaban than with dabigatran, as was all-cause mortality and gastrointestinal bleeding. Rivaroxaban was comparable to warfarin for major bleeding, with an increased risk in gastrointestinal bleeding and decreased risk of intracranial hemorrhage.

Risk of Pulmonary Embolism After Cerebral Venous Thrombosis Clinical Sciences
Background and Purpose—Cerebral vein thrombosis (CVT) is a type of venous thromboembolism. Whether the risk of pulmonary embolism (PE) after CVT is similar to the risk after deep venous thrombosis (DVT) is unknown.Methods—We performed a retrospective cohort study using administrative data from all emergency department visits and hospitalizations in California, New York, and Florida from 2005 to 2013. We identified patients with CVT or DVT and the outcome of PE using previously validated International Classification of Diseases, Ninth Revision, Clinical Modification codes. Kaplan–Meier survival statistics and Cox prop...

Ten-Year Temporal Trends in Medical Complications After Acute Intracerebral Hemorrhage in the United States Clinical Sciences
Conclusions—Despite significant mortality reduction, ARF and DVT risk after ICH have increased, whereas odds of sepsis and pneumonia have declined over the last decade. All complications were associated with increased cost and length of stay, but their associations with mortality were variable, likely due in part to survival bias. Innovative strategies are needed to prevent ICH-associated medical complications.

Acute Cerebral Venous Thrombosis Clinical Sciences
Background and Purpose—Cerebral venous thrombosis (CVT) affects venous hemodynamics and can provoke severe stroke and chronic intracranial hypertension. We sought to comprehensively analyze 3-dimensional blood flow and hemodynamic alterations during acute CVT including collateral recruitment and at follow-up.Methods—Twenty-two consecutive patients with acute CVT were prospectively included and underwent routine brain magnetic resonance imaging (MRI) and 4-dimensional flow MRI at 3 T for the in vivo assessment of cerebral blood flow. Neurological and MRI follow-up at 6 months was performed in 18 patients.Results—Three...

Coexistent Sickle Cell Disease Has No Impact on the Safety or Outcome of Lytic Therapy in Acute Ischemic Stroke Clinical Sciences
Conclusions—Coexistent SCD had no significant impact on the safety or outcome of thrombolytic therapy in acute ischemic stroke. Although the sample size is relatively small, these data suggest that adults with SCD and acute ischemic stroke should be treated with thrombolysis, if they otherwise qualify. Addition studies, however, should track the intracranial hemorrhage rate and provide information on other SCD-related care such as transfusion.

Intravenous Thrombolysis in Unknown-Onset Stroke Clinical Sciences
Conclusions—Our data suggest no excess risk of symptomatic intracerebral hemorrhage but increased mortality and reduced favorable outcome in patients with UKO stroke compared with patients treated within the approved time window.

Venous Thrombotic Recurrence After Cerebral Venous Thrombosis Clinical Sciences
Conclusions—In our cohort of CVT patients followed on average for>6 years, subjects with a previous venous thrombotic event, cancer/malignant hemopathies, and unknown CVT causes were found to be at higher risk of recurrence.

Is Unexplained Early Neurological Deterioration After Intravenous Thrombolysis Associated With Thrombus Extension? Clinical Sciences
Conclusions—In this study, unexplained END occurring after thrombolysis was independently associated with susceptibility vessel sign extension, suggesting in situ thrombus extension or re-embolization. These findings strengthen the need to further investigate early post-thrombolysis administration of antithrombotics to reduce the risk of this ominous clinical event.

Infarct Pattern and Collateral Status in Adult Moyamoya Disease Clinical Sciences
Conclusions—In the studied population of adult MMD patients, embolic phenomenon played an important role in ischemic stroke. Therapeutic strategies against thromboembolism, as well as collateral enhancing strategies targeting improvement of hemodynamic status or increased washout of emboli, are warranted.

Baseline Predictors of Poor Outcome in Patients Too Good to Treat With Intravenous Thrombolysis Clinical Sciences
Conclusions—Approximately one third of patients deemed too good for intravenous tissue-type plasminogen activator are unable to be discharged directly to home. Given the current safety profile of intravenous tissue-type plasminogen activator, our results suggest that the concept of being too good to treat should be re-examined with an emphasis on the features associated with poor outcome identified in our study. If replicated, these findings could be incorporated into tissue-type plasminogen activator decision-making algorithms.
