Intravenous Thrombolysis Resulting In Acute Ischemic Stroke Recanalization Can Lead To Cerebral Hyperperfusion Syndrome (P7.123)
Conclusion- Cerebral hyperperfusion syndrome after intravenous thrombolysis in acute ischemic stroke should be suspected in patients that achieve arterial recanalization and develop unexplained new neuropsychiatric manifestations.Disclosure: Dr. Ong has nothing to disclose.

Carotid stenting and intracranial thrombectomy for treatment of acute stroke due to tandem occlusions with aggressive antiplatelet therapy may be associated with a high incidence of intracranial hemorrhage
Conclusions Primary stenting of the extracranial carotid artery combined with intracranial mechanical thrombectomy can be an effective treatment for tandem occlusions, can be performed with a high rate of technical success, and can achieve good clinical outcomes in selected patients. However, the incidence of SICH may be higher than in other patient populations and may be associated with the use of abciximab and advanced patient age.

Unlabeled amphetamine isomer in sports supplement “probably” caused hemorrhagic stroke
3.5 out of 5 stars Hemorrhagic Stroke Probably Caused by Exercise Combined With a Sports Supplement Containing β-Methylphenylethylamine (BMPEA): A Case Report. Cohen P et al. Ann Intern Med 2015 May 12 [Epub ahead of print] Reference Last month, the FDA sent letters to 5 companies that manufacture so-called “dietary” or “sports” supplements, warning them that their products were mislabeled because they contained an unlisted ingredient. That ingredient, β-methylphenylethylamine (BMPEA), is an isomer of amphetamine. Although the effects of BMPEA in humans have not been well studied, it has been ...

Risk Reduction of Cerebral Stroke After Stereotactic Radiosurgery for Small Unruptured Brain Arteriovenous Malformations Clinical Sciences
Conclusions— SRS can significantly reduce the risk of stroke in the patients with small unruptured arteriovenous malformations. To definitively determine the clinical benefits of SRS, a longer follow-up will be necessary. However, based on our results, we can recommend SRS for patients who face a latent risk for stroke from this intractable vascular disease.

Similar Outcomes for Contact Aspiration and Stent Retriever Use According to the Admission Clot Burden Score in ASTER Clinical Sciences
Conclusions—First-line mechanical thrombectomy with contact aspiration compared with stent retriever did not result in an increased successful reperfusion rate in acute ischemic stroke patients with large vessel occlusion of the anterior circulation according to the admission CBS. The latter, however, seems to be a reliable prognostic indicator of angiographic and clinical outcome.

The Value of Whole-Brain Perfusion Parameters Combined with Multiphase Computed Tomography Angiography in Predicting Hemorrhagic Transformation in Ischemic Stroke
Objective: To explore the value of whole-brain perfusion parameters combined with multiphase computed tomography angiography (MP-CTA) in predicting the hemorrhagic transformation (HT) of ischemic stroke. Methods: A total of 64 patients with ischemic stroke who underwent noncontrast computed tomography, computed tomography perfusion imaging, and computed tomography angiography before treatment from August 2017 to June 2019 were included retrospectively. The perfusion parameters cerebral blood volume (CBV), cerebral blood flow (CBF), time to peak (TTP), mean transit time (MTT), time to maximum (Tmax), and permeability surfac...

CT Perfusion Maps Improve Detection of M2-MCA Occlusions in Acute Ischemic Stroke
A growing body of literature supports mechanical thrombectomy-based endovascular therapy for M2-MCA occlusions in eligible patients with acute ischemic stroke (AIS).1 –5 This is because endovascular treatment for M2-MCA occlusions is technically feasible and leads to improved patient outcomes, despite a potential increased risk of hemorrhage.4,5 Not uncommonly, these patients undergo a single or multi-phase CT angiogram (CTA) study for LVO detection. In patient s who present in the late stroke window (6–24 h since last known normal), the CT Perfusion (CTP) study is generally performed along with a CTA study to aid in patient triage.

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...

Demographic and Clinical Predictors of Leptomeningeal Collaterals in Stroke Patients
Background: Leptomeningeal collaterals improve outcome after stroke, including reduction of hemorrhagic complications after thrombolytic or endovascular therapy, smaller infarct size, and reduction in symptoms at follow-up evaluation. The purpose of this study was to determine the demographic and clinical variables that are associated with a greater degree of cerebral collaterals.Methods: Clinical data of patients presenting with M1 occlusions of the middle cerebral artery (MCA) and associated computed tomography angiography studies after admission from 3 separate institutions were retrospectively compiled (n = 82). Occl...

The disappearing thrombus: An uncommon cause of ischemic stroke
A 46-year-old woman presented with 2 episodes of transient left-sided paresis and hypoesthesia lasting 30 minutes. The emergency department initiated a stroke code due to reoccurrence of symptoms. Workup revealed a platelet count of 1,141,000, and CT angiography showed a large pedunculated thrombus within the right internal carotid artery (figure 1). She underwent emergent plateletpheresis without an anticoagulant (unfractionated heparin, low molecular weight heparin). This was not started at the time of initial presentation because of increased bleeding risk in patients with either reactive or essential thrombocythemia.1 ...

Endovascular treatment for M2 occlusions in the era of stentrievers: a descriptive multicenter experience
Conclusions Endovascular treatment of M2 MCA occlusion with stentrievers seems safe. Induced recanalization may double the chances of achieving a favorable outcome, especially for patients with moderate or severe deficit.

Angiographic Blush after Mechanical Thrombectomy is Associated with Hemorrhagic Transformation of Ischemic Stroke
Risk factors for hemorrhagic transformation of ischemic stroke after mechanical thrombectomy (MT) are not well established. We conducted a study to determine if prominent angiographic cerebral vascularity following recanalization with thrombectomy (angiographic blush) is associated with hemorrhagic transformation.
