A clinical application study of a stent placement assessment
Discussion:
Currently, no prospective controlled data exist regarding the efficacy and safety of carotid stenting in the acute phase. Previously, we had developed an ECASES stent placement system for acute carotid artery occlusion. The present study will evaluate the efficacy and safety of ECASES in a randomized, double-blind prospective study and clarify its guiding significance in acute atherosclerotic carotid artery occlusion surgery.

Diffuse low-grade glioma misdiagnosed as acute cerebral infarction: A case report
We report a case of DLGG detected by computed tomography and magnetic resonance imaging (MRI).
Patient concerns:
A 58-year-old man suddenly phantom smells for half an hour and was previously healthy.
Diagnoses:
Computed tomography findings showed a leaf-shaped slightly hypodense shadow in the right temporal lobe with no obvious mass effect and an unclear boundary. MRI findings showed diffuse and slightly longer T1-weighted imaging (T1WI)/T2-weighted imaging (T2WI)signal in the right temporal lobe and hippocampus, slight hyperintensity on diffusion-weighted imaging, diffuse swelling in the right temporal lobe ...

Intramedullary spinal cord abscess associated with right-to-left shunt via right superior vena cava draining into left atrium: A case report
We report the first case of ISCA associated with RSVC-LA RL shunt.
Patient concerns:
A 36-year-old man developed progressive paraparesis, dysuria, and spontaneous pain in the lumbar region and lower extremities. Spinal magnetic resonance imaging revealed an intramedullary lesion extended from Th12 to L2 with ring-shaped gadolinium enhancement. Cerebrospinal fluid (CSF) study exhibited a marked pleocytosis, and CSF culture grew Streptococcus intermedius. Cardiovascular computed tomography angiography identified RSVC-LA RL shunt, which caused transient acute cardiac syndrome due to air embolus.
Diagnoses:
The p...

Prognostic factors for acute posterior circulation cerebral infarction patients after endovascular mechanical thrombectomy: A retrospective study
This article was to analyze the factors influencing the prognosis of posterior circulation cerebral infarction (PCCI) patients, retrospectively.
One hundred forty five patients diagnosed with PCCI in Nanyang Central Hospital between June 25, 2016 and October 14, 2019 were included and underwent cerebral vascular mechanical thrombectomy. The clinical data of those patients were collected. The patients were followed up for 3 months to observe the prognostic efficacy and explore the influencing factors for poor prognosis. The potential prognostic factors for PCCI patients after emergency endovascular mechanical thrombect...

Added value of systemic inflammation markers in predicting pulmonary infection in stroke patients: A retrospective study by machine learning analysis
This study aimed to develop machine learning (ML)-based predictive models for pulmonary infection.
Between January 2008 and April 2021, a retrospective analysis of 1397 stroke patients who had CT angiography from skull to diaphragm (including CT of the chest) within 24 hours of symptom onset. A total of 21 variables were included, and the prediction model of pulmonary infection was established by multiple ML-based algorithms. Risk factors for pulmonary infection were determined by the feature selection method. Area under the curve (AUC) and decision curve analysis were used to determine the model with the best resolut...

Endovascular therapy for acute basilar artery occlusion caused by vertebral artery dissection: Case report
We describes a case of basilar artery (BA) occlusion caused by extracranial VAD, in which we used a stent-retriever to achieve thrombectomy in the BA through the contralateral vertebral artery (VA).
Patient concerns:
A 32-year-old male presented with a sudden-onset headache accompanied by articulation disorder, left-sided weakness, and tinnitus in the left ear.
Diagnosis:
Digital subtraction angiography showed the V1 to V2 segment dissection of the left VA and occlusion of the BA.
Interventions:
Thrombectomy was performed through the thinner right VA with three passes of the Solitaire FR device 4 ×â...

Vertebral artery hypoplasia as an independent risk factor of posterior circulation atherosclerosis and ischemic stroke
Vertebral artery hypoplasia (VAH) is a frequent anatomical variation of vertebral arteries, with emerging evidence suggesting that it contributes to posterior circulation ischemia. However, the relationship between VAH and ischemic stroke remains unknown. Hence, this study aimed to determine the prevalence of VAH in patients diagnosed with acute ischemic stroke who were followed up in a neurology clinic and to determine if it can potentially be a risk factor for atherosclerotic stenosis in vertebrobasilar circulation.
This retrospective study included 609 patients diagnosed with acute ischemic stroke between January 1, ...

Reversible cerebral vasoconstriction syndrome with basilar artery stenosis: A case report
Conclusions:
A headache in young patients with risk factors of atherosclerosis, such as smoking history, uncontrolled hypertension, and dyslipidemia may be caused by reversible cerebral vasoconstriction syndrome or ischemic stroke, which has fatal neurological complications. Therefore, reversible cerebral vasoconstriction syndrome or ischemic stroke should be suspected and appropriately evaluated in such patients, even if the headache is not the thunderclap type.

The clinical outcomes of mechanical thrombectomy for proximal M1 occlusion involving lenticulostriate perforators: Is it worse than distal M1 occlusion? Retrospective observational study
Although the success rate of recanalization in acute intracranial artery occlusion is high, there is a poor rate of improvement in functional clinical outcome. The purpose of this study was to assess the functional outcome of mechanical thrombectomy for proximal M1 occlusion involving lenticulostriate arteries (LSAs) compared with distal M1 occlusion-sparing the LSAs.
A retrospective analysis was conducted in patients with middle cerebral artery (MCA) M1 occlusions who had a successful recanalization subsequent to mechanical thrombectomy. The recanalization results were estimated using the thrombolysis in cerebral infar...

Basilar dolichoectasia with intermural hematoma accompanied by cerebral microbleeds and white matter hyperintensities: A case report
Rationale:
The clinical manifestations of basilar dolichoectasia (BD) are variable. The diagnosis is based on imaging measurements. Digital subtraction angiography displays only the dilated vascular lumen and lacks visualization of the arterial wall. High-resolution Magnetic resonance imaging (MRI) can identify intramural hematoma; therefore, it may be more suitable for the imaging evaluation of BD. However, most of the existing literature pertaining to BD lacks vascular wall assessment.
Patient concerns:
A 65-year-old Chinese man perceived weakness of the left upper and lower limb, double vision, dizziness, nau...

Intracardiac thrombus in a patient with mitral bioprosthesis and atrial fibrillation treated with direct oral anticoaugulant: A case report
Rationale:
Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased morbidity, especially stroke and heart failure. There is also increasing awareness that atrial fibrillation is a major cause of embolic events which in 75% of cases are complicated by cerebrovascular accidents.
Patient concerns:
A 50-year-old woman with mitral bioprosthesis under warfarin for nonvalvular atrial fibrillation was referred to our Coronary Intensive Care Unit due to acute myocardial infarction without evidence of significant coronary artery stenosis.
Diagnoses:
Cardiovascular examination...

Y-configuration double-stent-retriever thrombectomy for refractory thrombus in middle cerebral artery bifurcation: A case report
Rationale:
Stent retriever mechanical thrombectomy is a recommended treatment for acute ischemic stroke. However, refractory thrombus in artery bifurcation can reduce the rate of successful revascularization.
