The aim of this study was to review cases of pediatric arterial ischemic stroke among Chinese subjects and thereby evaluate risk factors, clinical and neuroimaging features, and treatment, to establish a reasonable guideline for assessment and management of the disease. Between 1996 and 2006, 157 children (male:female ratio, 1.4:1) with arterial ischemic stroke were identified at Beijing Children's Hospital. The median age at stroke was 32 months (range, 4-192). Among patients with determined etiology, infections (12.1%), moyamoya disease (12.1%), and trauma (10.8%) were the most common. In 51 patients, there were no obvious risk factors (32.5%). Hemiplegia was the most common presenting feature (81.5%). The region of left middle cerebral artery was most frequently affected (36.3%), followed by the right middle cerebral artery (29.9%). Of the 157 patients, 56 were treated by intravenous thrombolytic agents (35.7%), all but one of them successfully (the one exception involving hemorrhagic complication). Randomized controlled trials are needed to establish primary prevention, acute treatment, and secondary prevention of pediatric ischemic stroke.

Mechanisms of Autophagy in Ineffective Reperfusion After Ischemic Stroke.

Despite significant advancements in achieving high recanalization rates (80%-90%) for large vessel occlusions through mechanical thrombectomy, the issue of "futile recanalization" remains a major clinical challenge. Futile recanalization occurs when over half of patients fail to experience expected symptom improvement after vessel recanalization, often resulting in severe functional impairment or death. Traditionally, this phenomenon has been attributed to inadequate blood flow and reperfusion injury.

Background: Accurate distinction between stroke etiologic subtypes is critical for physicians to provide tailored treatment. The triglyceride-glucose (TyG) index, a marker of insulin resistance, has been associated with stroke risk but its role in distinguishing stroke etiologic subtypes remains unclear. We aimed to assess the TyG index's ability to differentiate cardioembolic (CE) from non-cardioembolic (NCE) strokes.

Background: Ischemic stroke is a prevalent and life-threatening cerebrovascular disease that is challenging to treat and associated with a poor prognosis. Astragaloside IV (AS-IV), a primary bioactive component of Astragali radix, has demonstrated neuroprotective benefits in previous studies. This study aimed to explore the mechanisms through which AS-IV may treat cerebral ischemia-reperfusion injury (CIRI).

Angioplasty and stenting of brachiocephalic artery stenosis can be complicated by ischemic stroke, local hematoma, thromboses, or dissection of access vessels. However, hemodynamic instability has not been reported as a complication of this treatment. We report the case of an 83-year-old man who developed hypotension and bradycardia after brachiocephalic artery stenting.

Objective: The optimal timing of bypass surgery for patients with moyamoya disease (MMD) or moyamoya syndrome (MMS) following an acute stroke episode remains unclear, mainly owing to the risk of postoperative complications. In this study, we aim to validate the safety and efficacy of early intervention using multiple burr hole (MBH) and erythropoietin (EPO) therapy, thereby refining the management strategy for patients with acute stroke episode of MMD or MMS.
Methods: We retrospectively analyzed data from 70 patients with MMD or MMS who underwent MBH and EPO therapy.
