We present the case of a 39-year-old woman who developed an ischemic cerebral infarction after using cocaine. Initially the patient was thought to suffer from a psychiatric disorder, and a computed tomography (CT) scan at the time of admission was entirely normal. Further evaluation of the patient by staff on the Psychiatric Unit led to the suspicion that she had suffered a stroke. A repeat CT scan on the third hospital day showed a large infarction in the left middle cerebral artery territory. We discuss the diagnosis of cerebral infarction with subtle presentations due to cocaine use.

Objectives: To assess the efficacy of endovascular treatment and clinical outcomes in individuals with symptomatic intracranial stenosis who had not responded adequately to medical intervention.
Methods: The study included 32 patients who received endovascular treatment due to high-grade (70%-99% severity) intracranial atherosclerotic stenosis from December 2021 to December 2023. The patients had not experienced any acute ischemic or hemorrhagic infarction within the last three weeks, had a Modified Rankin Scale score of ≤3 at baseline, and developed a transient ischemic attack or non-disabling stroke despite having received the best medical treatment.

Coronary heart disease (CHD) remains a leading cause of mortality in Indonesia, and coronary artery bypass graft (CABG) surgery is frequently employed to manage arterial blockages. Despite its efficacy, the recurrence of heart disease post-surgery is a significant concern, highlighting the need for a deeper understanding of its influencing factors. The aim of this study was to examine the factors associated with the incidence of heart disease recurrence after coronary bypass surgery.

Ischemic stroke is a sudden onset of neurological deficit resulting from a blockage in cerebral blood vessels, which can lead to brain tissue damage, chronic disability, and increased risk of mortality. Secretome from hypoxic mesenchymal stem cells (SH-MSC) is a potential therapy to improve neurological deficit by increasing the expression of vascular endothelial growth factor (VEGF) and reducing glial fibrillary acidic protein (GFAP). These effects can reduce the infarction area of ischemic stroke.

Aim: This study aims to report a rare case of an embolization protection device (EPD) entrapment during Carotid Artery Stent (CAS) and to discuss the management strategy, including open surgery and concurrent carotid endarterectomy (CEA).
Case Presentation: A 71-year-old female presented with left limb weakness and unclear speech following CAS. Imaging revealed a new cerebral infarction and right internal carotid artery stenosis.

Background: Hemorrhagic transformation (HT) is a complication of reperfusion therapy following acute ischemic stroke (AIS). We aimed to develop and validate a model for predicting HT and its subtypes with poor prognosis-parenchymal hemorrhage (PH), including PH-1 (hematoma within infarcted tissue, occupying < 30%) and PH-2 (hematoma occupying ≥ 30% of the infarcted tissue)-in AIS patients following intravenous thrombolysis (IVT) based on noncontrast computed tomography (NCCT) and clinical data.
Methods: In this six-center retrospective study, clinical and imaging data from 445 consecutive IVT-treated AIS patients were collected (01/2018-06/2023).
