We report a case of thrombosis of superior sagittal and cavernous sinuses treated by direct instillation of fibrinolytic agents via selective catheterization. Despite risk of bleeding related to the pathology and treatment, no adverse side-effect occurred. This report is unusual regarding the poor initial clinical patient's condition with dilated and unreactive pupil. The good neurologic outcome warrants aggressive treatment in the most severe forms of cerebral venous thrombosis.

Idiopathic pulmonary arteriovenous malformation: a rarity in clinical practice.
J Vasc Bras
January 2025
Universidade Federal da Paraíba - UFPB, Hospital Universitário Lauro Wanderley - HULW, João Pessoa, PB, Brasil.
Pulmonary arteriovenous malformations (PAVM) are characterized by abnormal pulmonary vessels forming arteriovenous shunts that compromise oxygenation of the blood, causing hypoxemia, and predispose to infections and cerebral ischemia. The patient in this case was a 38-year-old male who presented with tachypnea and dyspnea, cyanosis of extremities, and significant digital clubbing. The patient had structural epilepsy secondary to neurosurgery for a cerebral abscess during childhood.

The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).
Methods: The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing.
Association Between Cannula Size of Extracorporeal Membrane Oxygenation and Prognosis in Patients With Out-of-Hospital Cardiac Arrest - A Secondary Analysis of the SAVE-J II Study.
Circ J

Department of Cardiovascular Medicine, National Cerebral and Cardiovascular Center.
Background: Selecting an appropriate cannula size is crucial for achieving an adequate extracorporeal membrane oxygenation (ECMO) flow rate. However, the association between ECMO cannula size and the prognosis of patients with out-of-hospital cardiac arrest (OHCA) has not been fully elucidated. We examined the associations between ECMO cannula size and neurological outcomes and survival at discharge in patients with OHCA who received ECMO.

To what extent sildenafil, a selective inhibitor of the type-5 phosphodiesterase modulates systemic redox status and cerebrovascular function during acute exposure to hypoxia remains unknown. To address this, 12 healthy males (aged 24 ± 3 y) participated in a randomized, placebo-controlled crossover study involving exposure to both normoxia and acute (60 min) hypoxia (Fi = 0.14), followed by oral administration of 50 mg sildenafil and placebo (double-blinded).

Background: Cerebral venous sinus thrombosis (CVT) is a rare cause of stroke, constituting 0.5-3% of all strokes with an extremely varied spectrum of presentation, predisposing factors, neuroimaging findings, and eventual outcomes. A high index of suspicion is needed because timely diagnosis can significantly alter the natural course of the disease, reduce acute complications, and improve long-term outcomes.
