Incidence and case-fatality rate of stroke in General Villegas, Buenos Aires, Argentina. The EstEPA population study.

Objectives: Stroke epidemiology varies among different populations. The burden of stroke is high in low- and middle-income countries. Reliable population data is needed to assess the impact of stroke and to develop policies aimed to improve stroke care in our region.

[Recommendations For The Management Of Spontaneous Intracerebral Hemorrhage During Hospitalization].

Stroke is the leading cause of neurological disability in people over 40 years of age and the fourth leading cause of death in Argentina. In the last ten years, the indexed publications related to the treatment of ischemic stroke were more numerous than those of hemorrhagic stroke. The objective of this material is to provide local and updated recommendations for the management of patients with spontaneous intracerebral hemorrhage during hospitalization.

[Use and results of intravenous fibrinolysis in a stroke unit].

Intravenous fibrinolysis with recombinant tissue plasminogen activator (rTPA) and use of stroke units improve morbidity and mortality in patients with acute ischemic stroke (AIS). However, data published in Argentina are scarce. We describe the experience in the use of fibrinolysis in patients with acute ischemic stroke (AIS) before and after the implementation of a stroke unit in a Comprehensive Stroke Center in Buenos Aires during the last 17 years.

Mechanical thrombectomy for reperfusion of acute ischemic stroke in a Stroke Unit in Argentina.

Objective: Stroke is an important cause of morbidity and mortality worldwide. Reperfusion therapy with intravenous tissue plasminogen activator (IV-tPA) was first implemented in 1996. More recently, endovascular reperfusion with mechanical thrombectomy (MT) demonstrated a robust beneficial effect, extending the 4.

A Population-Based Survey of Stroke Knowledge in Argentina: The SIFHON Study.

Background And Objectives: Information about stroke awareness in Latin America is scant. We conducted a large population survey in Argentina to assess stroke knowledge.

Methods: We distributed 110,000 multiple-choice anonymous questionnaires using the house distribution system of a bottled water dispensing company.

Detection of Subclinical Atherosclerosis in Subclavian Arteries of Subjects with Vascular Risk Factors and Normal Carotid Ultrasound.

Background And Purpose: Most risk scores that use imaging methods to determine the presence of subclinical atherosclerosis assess the carotid and coronary arteries. The value of assessing subclavian arteries to improve the predictive capacity of traditional imaging studies is not known.

Materials And Methods: We studied subjects without cardiac, cerebral, or peripheral vascular symptoms and normal carotid ultrasound.

[Post-stroke epilepsy].

Stroke is the most common cause of seizures and epilepsy in population stuies of adults. Seizures occur within 24 hours of the stroke in a high percent of patients. The pathogenesis of these early-onset seizures may be related to local ion shifts and release of high levels of excitotoxic neurotransmitters in the area of ischemic injury.

Cortical Spreading Depression and Ischemia in Neurocritical Patients.

Spreading depolarization in cerebral cortex is associated with swelling of neurons, distortion of dendritic spines, massive ion translocation with a large change of the slow electrical potential, and silencing of brain electrical activity. The term spreading depression represents a wave of spontaneous activity of the electrocorticogram that propagates through contiguous cerebral gray matter at a characteristic velocity. Spreading depression is a consequence of cortical spreading depolarization.

Spontaneous Cystic Arteriovenous Malformation-A Novel Treatment Alternative.

Background: Brain arteriovenous malformation (BAVM) is a life-threatening vascular congenital malformation due to the risk of intracerebral hemorrhage. The formation of a spontaneous cyst within a BAVM, without history of hemorrhage or gamma knife surgery, is rare and has an unknown pathophysiology. We suggest a novel theory of spontaneous cystic BAVM formation, subsequently treated with endovascular embolization followed by surgery with a favorable long-term outcome.

Left atrial appendage occlusion with Amplatzer Cardio Plug is an acceptable therapeutic option for prevention of stroke recurrence in patients with non-valvular atrial fibrillation and contraindication or failure of oral anticoagulation with acenocumarol.

Unlabelled: Left atrial appendage occlusion (LAAO) appears as a therapeutic option for some atrial fibrillation patients not suitable for oral anticoagulation because an increased hemorrhagic risk or recurrent ischemic events despite anticoagulant treatment.

Methods: Report of consecutive atrial fibrillation patients treated with LAAO with Amplatzer Cardio Plug because contraindication or failure of oral anticoagulation with acenocumarol. CHA2DS2VASC, HAS-BLED, NIHSS, mRS, procedural complications and outcome were assessed.

[In-hospital mortality due to stroke].

Overall mortality due to stroke has decreased in the last three decades probable due to a better control of vascular risk factors. In-hospital mortality of stroke patients has been estimated to be between 6 and 14% in most of the series reported. However, data from recent clinical trials suggest that these figures may be substantially lower.
