Large pulmonary arteriovenous malformations (PAVMs) constitute an uncommon cause of central cyanosis with septic embolism and brain abscess. This large right to left shunt can lead to chronic severe hypoxemia and significant morbidity and mortality if untreated. Conservative parenchyma-sparing lung
BACKGROUND Patent foramen ovale (PFO) are common, normally resulting in a left-to-right shunt or no net shunting. Pulmonary embolism (PE) can cause sustained increased pulmonary vascular resistance (PVR) and right atrial pressure. Increasing positive end-expiratory pressure (PEEP) improves
A 73-year-old man was admitted complaining of violent involuntary movement in the left upper and lower extremities. He had a ten-year history of hypertension and had had a left thalamic hemorrhage 6 years before admission. On neurological examination Horner's sign in the right eye, typical
BACKGROUND
Arterial gasometry is considered the gold standard for establishing a diagnosis of respiratory failure of any etiology. However, there are some circumstances in which it loses specificity, making necessary to consider other tests such as pulse oximetry to adequately determine hypoxemia.
The effect of hypoxia on neurological function, compressed spectral array electroencephalography, and histopathology in head-injured rats was evaluated. By itself, an hypoxic insult (PaO2, 40 mm Hg for 30 minutes) caused no neurological deficit. Twenty per cent of rats injured by a 5-atmosphere
Routine determination of the pH in umbilical arterial blood immediately after delivery is a commonly employed variable for assessing the risk of subsequent cerebral paresis caused by hypoxia. Opinions differ regarding the lower limit for normal NS-pH (acidosis limit) and this is due mainly to
The case of a 7-year-old child is presented, who suffered circulatory arrest during induction of anaesthesia for surgery for a posterior fossa tumour. A brain ischaemia lasting 6 minutes duration had to be assumed. After restoration of circulation, 825 mg ethiopenta were administered in order to
A recent article by Farrell et al. characterizes the phenomenon, mechanisms, and treatment of a local and severe hypoperfusion/hypoxia event that occurs in brain regions following a focal seizure. Given the well-established role of cerebral ischemia/hypoxia in brain damage and behavioral dysfunction
Cerebral abscess is a recognized complication of pulmonary arteriovenous malformations (PAVMs) that allow systemic venous blood to bypass the pulmonary capillary bed through anatomic right-to-left shunts. Broader implications and mechanisms remain poorly explored.
Between June 2005 and December
Hydranencephaly is a severe brain condition characterized by complete or almost complete absence of cerebral cortex with preservation of meninges, basal ganglia, pons, medulla, cerebellum, and falx. It has been ascribed to different causes (infections, irradiations, fetal anoxia, medications,
A 29-year-old male was admitted to our hospital for further evaluation of left sided paresis, cyanosis, clubbing finger. The laboratory data revealed polycythemia and hypoxemia. Cerebralarteriogram showed right middle cerebral artery occulusion. Cardiofunctional test showed atrial fibrillation,
We report the case of a 49-years-old patient who presented to the accident and emergency department with sudden onset dyspnea associated with acute shoulder pain. He was breathless at rest with supine hypoxemia. He had an amyotrophic left shoulder with localized paresis of the shoulder. Both
The purpose of this study was to determine the effectiveness and associated problems of emergency intubation in 605 injured infants and children admitted to the Children's Hospital of Pittsburgh in 1987. We identified 63 patients (10.4%) undergoing endotracheal intubation at the scene of injury, at
Obstruction of the upper and lower airways is common in horses. In the upper airway, paresis of abductor muscles of the nares and larynx allows inspiratory collapse of soft tissues, which is accentuated by factors increasing upper airway resistance and by high inspiratory flow rates. Intrapulmonary
