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...

Sex Differences in Revascularization Interventions after Acute Ischemic Stroke
Conclusions: Over the last decade, women hospitalized for AIS in the United States were less likely than men to receive cerebrovascular and cardiac reperfusion therapies. However, the IV tPA treatment sex disparity may have been eliminated.

Spontaneous Isolated Posterior Inferior Cerebellar Artery Dissection: Rare but Underdiagnosed Cause of Ischemic Stroke
Conclusions: Clinical manifestations in ischemic type of spontaneous isolated PICAD were similar to those of intracranial vertebral artery dissection. Clinical course was relatively stable and benign. SWI was more helpful to suspect abnormality of posterior inferior cerebellar artery than conventional MRI or magnetic resonance angiography in our small series. Cerebral angiography is recommended in patients with clinically suspected spontaneous isolated PICAD for definite diagnosis.

Larger A1/M1 Diameter Ratio Predicts Embolic Anterior Cerebral Artery Territorial Stroke Brief Reports
Conclusions— Larger ipsilateral A1 diameters and A1/M1 diameter ratio are associated with embolic ACAS. These findings suggest that A1 diameters and M1 diameters are important in determining the path of emboli that reach the terminal internal carotid artery.

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...

Stroke severity and incidence of acute large vessel occlusions in patients with hyper‐acute cerebral ischemia: results from a prospective cohort study based on CT‐angiography (CTA)
ConclusionAcute vessel occlusions are frequent in unselected patients. Occlusions occurred in all NIHSS score values but a NIHSS cut‐off value of 6 most optimally predicted acute vessel occlusion, even though accuracy was low.

Multimodal 3 Tesla MRI Confirms Intact Arterial Wall in Acute Stroke Patients After Stent-Retriever Thrombectomy Brief Reports
Conclusions— Our findings suggest that clinically relevant vessel wall injuries occur rarely after stent-retriever thrombectomy.

Y-Stenting for Bifurcation Aneurysm Coil Embolization: What is the Risk?
Authors: Spiotta AM, Lena J, Chaudry MI, Turner RD, Turk AS Abstract The use of two stents in a "Y" configuration (Y-stenting) to assist with coil embolization of complex bifurcation aneurysms has been accepted as an alternative to clip reconstruction of a select subset of challenging aneurysms. We review the risks associated with Y-stenting, including its procedural complication rates, angiographic occlusion rates, rerupture, and retreatment rates. PMID: 25120940 [PubMed]

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 ...

Clot Characteristics on Computed Tomography and Response to Thrombolysis in Acute Middle Cerebral Artery Stroke
Clinical and computer tomography angiography (CTA) correlates of hyperdense middle cerebral artery sign (HMCAS) and dot sign were revisited in patients treated for acute MCA stroke. Temporal evolution of these signs over 24 hours was assessed quantitatively by density (Hounsfield unit [HU]) measurements.

Endothelial Trauma From Mechanical Thrombectomy in Acute Stroke: In Vitro Live-Cell Platform With Animal Validation Basic Sciences
Conclusions— In vitro live-cell artificial vessel modeling enables a detailed study of the endothelium after thrombectomy and may contribute to future device design. Large animal studies confirm the relevance of this in vitro system to investigate endothelial physiology. This artificial vessel model may represent a practical, scalable, and physiologically relevant system to assess new endovascular technologies.

Why are most stroke patients deemed poor candidates for intraaterial therapy? A prospective study (P4.306)
Conclusion: The majority of patients presenting to a large tertiary referral center with AIS due to a large vessel occlusion were found to be poor IA candidates, with more than half excluded for a single reason. Such data addressing the volume and proportion of patients found ineligible for IA therapy in real-world practice can help target efforts to develop new interventional options and improve future clinical trial design.Disclosure: Dr. Damania has nothing to disclose.
