Perfusion Changes in Acute Stroke Treated with Theophylline as an Add-on to Thrombolysis
ConclusionThe results indicate that theophylline does not change the perfusion in potentially salvageable penumbral tissue but only affects the rCBV in the infarct core. In contrast to the penumbra, the infarct core is unlikely to be salvageable, which might explain why theophylline failed in clinical trials.

Questions on Predicting Early Neurological Deterioration in Patients With Minor Stroke and Large-Vessel Occlusion —Reply
In Reply We thank Ospel and colleagues for their thoughtful comments on our article showing that more proximal occlusion and greater thrombus length predict early neurological deterioration of ischemic origin (ENDi) in patients with acute minor ischemic stroke with large-vessel occlusion treated with intravenous thrombolysis, with implications regarding how to best manage these patients. Although the precise pathophysiological links between more proximal occlusion, a longer thrombus, and ENDi are uncertain, we fully agree that a leading hypothesis is in situ thrombus extension leading to secondary hemodynamic compromise vi...

Combined brain/heart magnetic resonance imaging in antiphospholipid syndrome-two sides of the same coin
AbstractAntiphospholipid syndrome (APS) is an autoimmune disorder characterized by arterial, venous, and/or small vessel thrombosis, pregnancy morbidity, and persistently elevated levels of antiphospholipid antibodies (aPL). Cardiovascular disease (CVD) in APS can present as heart valvular disease (HVD), macro-micro-coronary artery disease (CAD), myocardial dysfunction, cardiac thrombi, or pulmonary hypertension. Brain disease presents as stroke or transient ischemic attack (TIA) and less frequently as cerebral venous thrombosis, seizures, cognitive dysfunction, multiple sclerosis (MS) −like syndrome, or chorea. Infarcts...

Acute T2*-Weighted Magnetic Resonance Imaging Detectable Cerebral Thrombosis in a Rat Model of Subarachnoid Hemorrhage
AbstractSubarachnoid hemorrhage (SAH) is associated with a high incidence of morbidity and mortality, particularly within the first 72 h after aneurysm rupture. We recently found ultra-early cerebral thrombosis, detectable on T2* magnetic resonance imaging (MRI), in a mouse SAH model at 4 h after onset. The current study examined whether such changes also occur in rat at 24 h after SAH, the vessels involved, whether the degree of thrombosis varied with SAH severity and brain injury, and if it differed between male and female rats. Adult Sprague Dawley rats were subjected to an endovascular perforation SAH model or sham...

Atherosclerotic Components in Thrombi Retrieved by Thrombectomy for Internal Carotid Artery Occlusion Due to Large Artery Atherosclerosis: A Case Report
Conclusions: Atherosclerotic components in retrieved thrombi might provide useful clues for diagnosing stroke pathogenesis. Further studies are warranted to clarify the utility of assessing atheromatous components in retrieved thrombi in diagnosing stroke etiology.

Massive Brainstem and Cerebellum Infarction Due to Traumatic Extracranial Vertebral Artery Dissection in a Motor Traffic Accident: An Autopsy Case Report
Traumatic unilateral vertebral artery (VA) injury can cause focal thrombosis and may block the basilar artery which can further lead to ischemic stroke and massive cerebral infarction and subarachnoid hemorrhage and even rapid death. Here, we present an autopsy case with a traumatic extracranial VA dissection in a motor traffic accident, and the identification of cause of death underwent 2 autopsies. A 62-year-old male pedestrian collided with the right rearview mirror of a car and fell down to the ground. He complained pains in the head and neck. Head computed tomography (CT) showed a right linear temporal bone fracture a...

Localization of Infratentorial Lesion could Predict Patent Foramen Ovale as an Etiology in Embolic Stroke of Undetermined Source
CONCLUSIONS: Infratentorial lesions may be independently associated with PFO in patients with ESUS. The presence of infratentorial lesions could predict the presence of PFO in ESUS cases.PMID:33952811 | DOI:10.5551/jat.61200

Clinical-CT mismatch defined NIHSS ≥ 8 and CT-ASPECTS ≥ 9 as a reliable marker of candidacy for intravenous thrombolytic therapy in acute ischemic stroke
by Hung-Ming Wu, I-Hui Lee, Chao-Bao Luo, Chih-Ping Chung, Yung-Yang Lin
BackgroundClinical-diffusion mismatch between stroke severity and diffusion-weighted imaging lesion volume seems to identify stroke patients with penumbra. However, urgent magnetic resonance imaging is sometimes inaccessible or contraindicated. Thus, we hypothesized that using brain computed tomography (CT) to determine a baseline “clinical-CT mismatch” may also predict the responses to thrombolytic therapy. MethodsBrain CT lesions were measured using the Alberta Stroke Program Early CT Score (ASPECTS). A total of 104 patients were included: 79 pa...

Relationship Between Central Artery Stiffness, Brain Arterial Dilation, and White Matter Hyperintensities in Older Adults: The ARIC Study
CONCLUSIONS: In this examination of older adults from the general population, larger, plaque-free arterial diameters in the middle cerebral circulation were associated with greater WMH volume, particularly among participants with elevated central artery stiffness. Strategies to reduce central artery stiffness may mitigate the association between cerebrovascular outward remodeling and microvascular damage.PMID:33882687 | DOI:10.1161/ATVBAHA.120.315692
