Rescue extracranial vertebral stenting in tandem occlusions: A preliminary Vietnamese study.

Background And Purpose: The acute vertebrobasilar occlusion associated with the poor prognosis, particularly tandem occlusion. However, few data on the efficacy of the endovascular therapy was indicated in this occlusion. We investigated whether the additional rescue extracranial vertebral stenting improved clinical outcome by modified Rankin scale (mRS) score within 3 months after the procedure.

Prognosticating global functional outcome in the recurrent ischemic stroke using baseline clinical and pre-clinical features: A machine learning study.

Background And Purpose: Recurrent ischemic stroke (RIS) induces additional functional limitations in patients. Prognosticating globally functional outcome (GFO) in RIS patients is thereby important to plan a suitable rehabilitation programme. This study sought to investigate the ability of baseline features for classifying the patients with and without improving GFO (task 1) and identifying patients with poor GFO (task 2) at the third month after discharging from RIS.

Cerebral venous sinus thrombosis related to SARS-CoV-2 infection in a pediatric patient: A case report.

Coronavirus disease 2019 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); it has recently been associated with several hematologic disorders. A 4-year-old boy who had SARS-CoV-2 10 months prior was admitted to the emergency department of our hospital with seizures. His SARS-CoV-2 IgG II level was 885.

Cross-circulation thrombectomy for acute middle cerebral artery occlusion through a posterior communicating artery: a case report.

Background: Two concurrent instances of acute large vessel occlusion identified in two circulation systems is rare and associated with poor clinical outcomes. The complex vascular anatomy and chronic lesions involving extracranial or intracranial vessels may make classical anterograde approaches through parent vessels quite challenging. Besides, the effective treatment is required complicated and risky endovascular techniques.

Giant coronary artery fistula: A case report.

Coronary artery fistulas (CAFs) are abnormal connections of coronary arteries where venous circuits bypass the normal capillaries in the myocardium. CAFs are rare, and most patients are asymptomatic. However, CAFs are the most common coronary artery anomalies affecting coronary hemodynamics.

.

Top-of-the-basilar artery occlusion frequently causes infarction of the midbrain, thalamus, and portions of the temporal and occipital lobes as the vascular supply of these regions comes from the posterior communicating and posterior cerebral arterial tributaries of the basilar artery. Clinical signs include an array of visual, oculomotor, and behavioral abnormalities, usually without prominent motor dysfunction, which makes diagnosis challenging for those inexperienced with these sign. We describe a 59-year-old male presenting with acute ischemic stroke due to top-of-the-basilar artery occlusion.

Diagnostic determination by diffusion tensor imaging of neural axon injury between the 2 hemispheres following traumatic brain injury.

Traumatic brain injury (TBI) is caused by an external mechanical force to the head resulting in alteration of brain function. However, the injury to neural tracts and the connections between them is difficult to diagnose using traditional imaging techniques. A 54-year-old woman visited our clinic because of insufficient coordination of her body.

Recurrent head and neck arteriovenous malformations: A case report.

Head and neck arteriovenous malformations are rare, congenital, and high-flow vascular malformations characterized by abnormal communication between feeding arteries and draining veins without intervening capillaries. Arteriovenous malformations are considered the most dangerous type of vascular malformation because progressive symptoms and infiltration can result in potentially life-threatening consequences. Left untreated, arteriovenous malformations can cause significant cosmetic deformities, severe bleeding, and high-output cardiac failure associated with arteriovenous shunting.

A Complicated Case Report of Coronary Artery Fistula.

Background: Coronary artery fistulas (CAFs), also, known as coronary arteriovenous malformation, are aberrant connections between coronary arteries and other structures, such as other artery branches or heart chambers. CAFs are infrequent and asymptomatic in young patients, but symptoms and complications become more frequent with age. CAFs can affect hemodynamic parameters and lead to complications, such as myocardial ischemia, heart failure, arrhythmia, and infective endocarditis.

Discovery of super-insecticide-resistant dengue mosquitoes in Asia: Threats of concomitant knockdown resistance mutations.

(Linnaeus, 1762) is the main mosquito vector for dengue and other arboviral infectious diseases. Control of this important vector highly relies on the use of insecticides, especially pyrethroids. The high frequency (>78%) of the L982W substitution was detected at the target site of the pyrethroid insecticide, the voltage-gated sodium channel (Vgsc) of collected from Vietnam and Cambodia.

A rare case of fusiform basilar trunk aneurysm.

Aneurysms in the posterior circulation and distal sites are more common among the pediatric population than among adults, with a male predominance. Symptoms of an aneurysm in the posterior circulation can include a stiff neck or severe headache due to a ruptured aneurysm, whereas an unruptured aneurysm can cause mass effects or neurological deficits. However, in children, the complete occlusion of the aneurysm while preserving the flow of the main artery can be difficult to achieve when attempting a stent-assisted coil embolization technique.

Patient prioritization and management during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic affected the healthcare system in a major way generally. Healthcare re-organization of resources and manpower, establishing management protocols and specific patients' pathways are all evolving with the continuously changing situation. Neuro-vascular management and its re-organization are part of these global measures to cope with this pandemic in a way to establish less risky patients' pathways, help in patients' triage, protecting the staff by introducing training and applying safety measures and to manage neuro-vascular emergencies and elective activity.

Recurrent carotico-cavernous fistula after internal carotid artery ligation: a case with embolization of the fistula via contralateral internal carotid artery approach.

We are reporting a 51-year-old female patient having a history of direct carotid cavernous fistula (CCF) which was treated by internal carotid artery (ICA) ligation 17 year ago. She presented to Ho Chi Minh City University Medical Center with symptoms of recurrent CCF. The recurred CCF was supplied by multiple feeders coming from anterior, posterior communicating artery and the recanalized left ICA.

Direct traumatic carotid cavernous fistula: angiographic classification and treatment strategies. Study of 172 cases.

We report our experience in treatment of traumatic direct carotid cavernous fistula (CCF) via endovascular intervention. We hereof recommend an additional classification system for type A CCF and suggest respective treatment strategies. Only type A CCF patients (Barrow's classification) would be recruited for the study.

Winter refuge for Aedes aegypti and Ae. albopictus mosquitoes in Hanoi during Winter.

Dengue occurs throughout the year in Hanoi, Vietnam, despite winter low temperatures <10°C. During July 2010 to March 2012, we surveyed monthly for Aedes larvae and pupae in 120 houses in 8 Hanoi districts. Aedes albopictus preferred discarded containers in summer and pupal density drastically decreased in winter.

Filum terminale arteriovenous fistulas: the role of endovascular treatment.

Object: The authors describe the clinical presentation, imaging features, and management of patients presenting with filum terminale arteriovenous fistulas (FTAVFs) and the role of transarterial treatment in their management.

Methods: The authors retrospectively reviewed data obtained in 10 patients with FTAVFs diagnosed between January 1990 and December 2011.

Results: Most patients (70%) were male, and the age of the population ranged from 31 to 72 years (mean 58.
